Unit 4

Strengthening Arguments

About this unit

Given a claim or argument, identify the single piece of evidence that most directly and powerfully supports it. Questions cover health, education, environment, sport, policy, and everyday life — the key is finding what directly reinforces the stated conclusion.

What types of questions will you face?

  • 1A doctor or expert makes a claim — pick the answer that most strongly supports their argument
  • 2A real-world argument is presented — find the statement that best backs up the conclusion
  • 3A proposal or recommendation is made — identify which piece of evidence most directly validates it
  • 4A cause-and-effect claim is given — find the observation that most directly supports the causal link
  • 5An abstract principle is stated — select the example that most directly applies or demonstrates it

Skills you will build

  • Distinguishing direct supporting evidence from irrelevant or tangential information
  • Identifying what the argument actually needs to be true (its key assumption)
  • Evaluating whether evidence is specific enough to directly back the conclusion
  • Recognising when a distractor "sounds related" but doesn't logically support the claim
  • Understanding what makes evidence stronger or weaker for a particular claim

By the end of this unit, you will be able to

  • Instantly identify the one statement that most directly validates an argument
  • Filter out answers that are true or related but don't actually strengthen the specific claim
  • Understand the difference between supporting, weakening, and irrelevant evidence
  • Apply this skill to arguments across any topic you've never studied before

Difficulty profile

This is the easiest unit in the course (avg Very Easy). Most questions are straightforward — the correct answer directly and clearly supports the claim. Focus on eliminating distractors that are "true but unrelated".

Exam tip: Strengthening Arguments

Ask yourself: "If this answer were true, does it make the argument stronger or more believable?" The best answer directly supports the conclusion — not just something related to the topic.

Sample Questions

Lesson 1 of 14Strengthening ArgumentsIntroductory

The officer says motorcycle riders SHOULD wear helmets. Only option B gives a direct reason why — helmets reduce serious injury. The other options talk about cost, horse riders, and speed, none of which explain why helmets help motorcycle riders.

Safety recommendation questions (a professional says "people should do X") appear regularly in OC TS Strengthening Arguments questions. The correct support always gives a REASON why X is beneficial, not why the alternative is bad or why X is fashionable.

The examiner checks whether students can identify that supporting "X should happen" requires evidence that X produces a positive outcome — not evidence about cost/convenience (A), analogies from unrelated contexts (C), or contextually irrelevant comparisons (D).

A professional (police officer, doctor, specialist) makes a recommendation. Students must find the one statement that provides direct evidence that the recommended action is beneficial — usually a statistical or causal claim about reduced harm or improved outcomes.

Best approach: Ask: "Why should motorcycle riders wear helmets?" The correct answer must give a direct benefit of wearing helmets (reduced injury). Eliminate options about cost/weight (accessibility, not safety), analogies from different sports (irrelevant), and speed comparisons (doesn’t mention helmets).

Question

A police officer says: "Anyone riding a motorcycle should wear a helmet."

Which one of these statements, if true, best supports the police officer’s claim?

  1. AGood helmets are cheaper and lighter than they used to be.
  2. BYou are much less likely to suffer a serious injury if you are wearing a helmet.
  3. CPeople riding horses normally wear some sort of head protection.
  4. DMotorcycles can travel a lot faster than bicycles.

Lesson 2 of 14Strengthening ArgumentsIntroductory

An actor tells a school principal that children should have the chance to perform in plays or concerts. Which of four statements actually supports that advice? This is one of the cleanest strengthening questions in OC TS — three options miss the point entirely, and one option gives exactly the right reason.

Performing arts / school activity claims appear in OC TS strengthening questions every few exams. They are designed to test whether students can stay focused on the claim (benefit for children who perform) and not get distracted by adjacent facts (actor's reputation, audience enjoyment, other activities).

The examiner is checking whether students understand that a supporting statement must explain WHY the claim is beneficial — not just describe facts that are vaguely related. The three distractor options all feel loosely connected to the topic of performance but do not actually give a reason why it is important for children to perform.

A person (often an expert or community figure) makes a recommendation about something children or schools should do. You must find the statement that gives a direct benefit of doing that thing. Distractors typically describe: (1) the credibility of the speaker, (2) competing activities, (3) benefits to a different group (e.g. the audience instead of the performer).

Best approach: Ask: "Why is this activity important FOR THE CHILDREN?" Then scan the options for the one that completes the sentence: "This activity is important because ______." Option D fills the blank perfectly — performing builds confidence, which is a direct benefit for the children who participate. Reject options about the speaker's authority (A), unrelated activities (B), or benefits to spectators (C).

Question

An actor came to visit a local school. She gave the principal this advice: "It is important for children to be given the chance to perform in a school play or concert."

Which one of these statements, if true, best supports the actor's claim?

  1. AThe actor has given similar advice at many other schools.
  2. BChildren spend a lot of time playing sports and other games.
  3. CMany people enjoy watching plays or listening to concerts.
  4. DPerforming in front of other people helps to build confidence.

Lesson 3 of 14Strengthening ArgumentsIntroductory

Dylan runs to get fitter. His friend Angela tells him he should also swim if he wants to strengthen his whole body. Which statement best supports that advice? This is a very clean strengthening question — the goal is explicit (whole-body strength), and only one option explains why swimming achieves that goal. The others offer benefits of swimming that have nothing to do with strength.

Health and fitness activity claims appear regularly in OC TS strengthening questions. They are designed to test whether students can stay focused on the exact goal stated (here: whole-body strengthening) and not be distracted by other genuine benefits of an activity (relaxation, safety). A correct supporting statement must be relevant to the specific goal, not just to the activity in general.

The examiner is testing whether students understand that a supporting statement must directly address the claim's goal. Angela's claim is specifically about strengthening the whole body — not stress, not safety, not injuries. Only Option A directly connects swimming to whole-body muscle activation, which is the exact goal in question.

Person A does activity X. Person B recommends adding activity Y to achieve a specific outcome Z. You must find the statement that explains why Y specifically leads to outcome Z. Distractor options describe other real benefits of Y (relaxation, safety, fun) that are unrelated to the stated outcome Z.

Best approach: Underline the goal in Angela's claim: "strengthen your whole body." Then ask: which option explains why swimming achieves whole-body strength? Option A says swimming works more muscles than running — this directly closes the gap between running (partial muscle coverage) and the whole-body goal. Reject options about stress (B), safety (C), and running's downsides (D) — none of them explain why swimming specifically achieves whole-body strengthening.

Question

Dylan was keen to get fitter and stronger so he took up running. His friend Angela said to him: "If you want to strengthen your whole body, you should take up swimming as well as running."

Which one of these statements, if true, best supports Angela's claim?

  1. ASwimming uses more of the body's muscles than running.
  2. BSwimming can be quite relaxing and help reduce stress.
  3. CBeing able to swim well is good for your own personal safety.
  4. DPeople who run too much can sometimes damage their knees or ankles.

Lesson 4 of 14Strengthening ArgumentsIntroductory

A vet says handling kittens and puppies carefully is important for their proper development. Which statement best supports this? Option B gives a direct developmental benefit (less afraid of people = better social development). Options C and D are irrelevant to development; option A introduces a niche edge case that doesn't address the main claim.

Strengthening questions where the vet/expert makes a claim about a practice benefiting development or health appear regularly in OC TS. The correct answer always gives a specific, relevant benefit of the practice. Distractor D ('people enjoy it') is a classic trap — enjoyment is a real fact but has nothing to do with the animal's development.

The examiner is testing whether students can stay focused on the specific goal (pet's proper development) and find the option that explains how the practice (handling) achieves that goal (reduces fear, aids socialisation). Option D is a common trap because 'people enjoy it' is positive-sounding, but it's about the human experience, not the animal's development — which is what the vet's claim is about.

An expert recommends a practice for a specific group (pets, not wild animals) citing a benefit (proper development). The correct strengthening statement provides a concrete mechanism for how the practice produces the stated benefit. One distractor gives a real but irrelevant benefit (human enjoyment). One gives context about a completely different group (wild animals). One introduces an off-topic edge case (formerly wild pets).

Best approach: Focus on the vet's specific benefit claim: handling helps pets 'develop properly.' Ask: which option explains what that development actually looks like? Option B says handling reduces fear of people — that's a concrete developmental milestone (socialisation). Reject A (edge case about wild-turned-pets), C (about wild animals and food, unrelated to handling), and D (about human enjoyment, not pet development).

Question

A vet is talking about baby animals. She says: "In the case of wild animals, it's best to avoid touching them. But for kittens, puppies, and other pets at home, careful handling is important to make sure they're developing properly."

Which one of these statements, if true, best supports the vet's claim?

  1. ASome people have pets at home that were once wild animals.
  2. BHandling puppies and kittens often helps them to be less afraid of people.
  3. CMany people help wild animals by putting out food and water for them.
  4. DHandling puppies and kittens is something many people enjoy doing.

Lesson 5 of 14Strengthening ArgumentsIntroductory

A teacher claims that fixing leaking taps is the most effective way to reduce water waste at home. 'Most effective' is the critical phrase — you need a statement that explains why this method beats all other methods. Option C (leaking taps are the biggest source of waste) fills that gap directly. Options B and A are common traps: easy ≠ most effective, and scale of the problem ≠ best solution.

'Most effective / best / fastest' claim strengthening questions are a staple of OC TS Unit 4. The trap is usually an option that sounds positive but doesn't address the comparative superiority the claim requires. Students who don't lock onto the superlative ('most effective') often pick option A (confirms the problem exists) or option B (confirms ease).

The examiner is testing whether students can identify the specific logical gap in a superlative claim. The teacher says one method is the BEST — the gap is 'why is this method better than all others?' The answer must supply a reason for the superiority, not just a reason the method is good in general.

An expert or teacher recommends one specific action as the BEST way to achieve a goal. Four options are given. The correct option gives a reason that explains why this specific action is superior to alternatives (e.g. it targets the biggest source of the problem). A trap option confirms the action is easy or pleasant. Another trap confirms the problem is real but doesn't address which solution is best. A fourth trap option weakens the claim by noting there are alternatives.

Best approach: Spot the superlative: 'most effective', 'best', 'most important'. The gap is always the same: why is THIS method better than ALL others? The correct answer must provide a comparative reason (e.g. biggest source, greatest impact). Reject options that only confirm the problem exists (irrelevant to which solution is best) or that the solution is easy (easy ≠ most effective). Watch for options that actually weaken by saying there are many alternatives.

Question

During a science lesson, the teacher says that the most effective way to reduce water waste at home is to make sure that your taps are not leaking.

Which one of these statements, if true, best supports the teacher's claim?

  1. AA huge amount of water is wasted in people's homes every year.
  2. BIt is very easy to fix taps that are leaking.
  3. CLeaking taps are the biggest source of water waste in households.
  4. DThere are many different ways to reduce water waste at home.

Lesson 6 of 14Strengthening ArgumentsEasy

Strengthening Arguments questions are among the most consistently tested types in OC Thinking Skills — and once you understand what an argument actually needs, the correct answer almost jumps off the page.

A recommendation or claim followed by four possible supporting statements appears in virtually every OC TS test, often as one of the lower-difficulty items near the start. This makes it a reliable source of marks for prepared students.

The examiner wants to confirm that you can identify precisely what claim the argument is making and then select the one statement that directly validates that specific claim — not merely something that sounds related or is generally true.

A character gives advice or makes a recommendation. The correct supporting statement backs up the mechanism of the advice — the "why this approach works" — rather than a background detail, a vaguely related fact, or something that accidentally contradicts the argument.

Best approach: Ask yourself: "What would need to be true for this advice to actually work?" The correct answer answers that question directly. Eliminate options that are true but irrelevant to the specific claim — being interesting is not the same as being supporting evidence.

Question

Noa wants to become conversational in Gumbaynggirr.

Priya advises: "Spend a few weeks in Nambucca Heads — there are many fluent speakers you can practise with every day."

Which statement, if true, best supports Priya's advice?

  1. ANoa can travel to Nambucca Heads without too much difficulty.
  2. BLearning any language well always takes several years.
  3. CPriya has studied three other languages at evening college.
  4. DRegular conversation with fluent speakers is one of the fastest ways to build spoken fluency.

Lesson 7 of 14Strengthening ArgumentsEasy

Now for a more challenging variant — one where the correct supporting evidence is not obviously about the same topic as the argument. This is the type that catches even strong students off guard, because it requires following the logic rather than recognising the keywords.

This "parallel mechanism" strengthener appears regularly in the harder half of Strengthening Arguments questions. The test-maker deliberately places the correct answer in a completely different context to test whether you understand the argument's structure, not just its subject matter.

The examiner wants to see whether you can identify the underlying cause-and-effect mechanism an argument depends on and then recognise when evidence from an unrelated setting proves that same mechanism works. Topic is a distraction — logical structure is everything.

A character makes a claim based on a cause-and-effect theory (e.g. "changing the physical environment changes how people behave"). The correct strengthener proves this theory using a completely different example — a different place, a different action, the same logical structure.

Best approach: Strip the argument down to its bare logic: "If we do X, we get Y." Then test each answer: does it show the same X→Y relationship in any setting? The winning answer often describes a different topic entirely (a library, a train station) — but with the identical cause-and-effect pattern.

Question

The local council is debating a proposal to install more streetlights and clear away overgrown bushes in the city park. Councillor Reed argues this is a waste of money because lights and bushes don't stop people from committing crimes.

Councillor Park replies: "That is a narrow view. The physical environment directly dictates how people feel and act in a space. Improving the park's appearance will lead to a significant reduction in antisocial behaviour."

Which one of these statements, if true, most strengthens Councillor Park's argument?

  1. AA survey showed that 80% of residents are afraid to walk in the park after dark.
  2. BWhen the city painted over graffiti in the train station, instances of littering and vandalism in that area dropped by half.
  3. CThe cost of the new streetlights is lower than the cost of hiring extra security guards.
  4. DMost people who use the park for exercise prefer to go in the morning when it is bright.

Lesson 8 of 14Strengthening ArgumentsEasy

The specialist claims dance should be as important as sport in school. Only option A directly justifies this — if dance improves mental abilities, it has proven value that earns equal time with sport. The other options either weaken sport, support sport, or simply note historical precedent.

Health or education claims with a "this activity is just as valuable as sport" structure appear regularly in OC TS Strengthening questions. The correct answer always proves the activity has a direct benefit — not that the rival activity has a flaw.

The examiner checks whether students can identify the precise claim being made (dance deserves equal priority) and select evidence that directly supports that claim rather than attacking the alternative or citing irrelevant history.

A specialist recommends giving activity X the same priority as activity Y. Students must find the one statement that validates why X deserves that status — not a statement that discredits Y or describes a past usage of X.

Best approach: Restate the claim in one sentence: "Dance deserves as much school time as sport." Then test each option: does it give a reason why dance is valuable enough to deserve equal time? The correct answer does exactly that; the distractors either attack sport (irrelevant), praise sport (counter-productive), or describe history (no causal force).

Question

A health specialist has suggested that dance lessons should be an important part of school life, and that school children should spend as much time learning to dance as they do playing sport.

Which one of these statements, if true, best supports the health specialist’s claim?

  1. ADancing improves children’s mental abilities.
  2. BSome children cannot afford equipment to participate in sports.
  3. CSome children dream of becoming professional sportspeople.
  4. DDancing has been taught in schools in the past.

Lesson 9 of 14Strengthening ArgumentsEasy

When someone makes a claim that something "affects us too," the supporting statement must show a direct path from the cause to people being harmed. This question is about ocean plastic pollution — and the correct answer is the one that completes the chain from "plastic in the ocean" all the way to "plastic reaching humans." It's a classic food-chain logic question dressed up as an environmental argument.

Claim-support questions involving environmental or health topics appear regularly in OC TS. The key challenge is that several options will sound true and relevant, but only one directly proves the specific thing the argument claims. Students who don't read the claim precisely often pick A or C — both are true facts, but neither shows ocean plastic harms people.

The examiner wants to check whether you can identify the precise claim being made ("it affects us") and select only the statement that directly evidences that specific claim — not background facts, not solutions, not related-but-irrelevant environmental data.

An expert makes a two-part claim: a known fact plus a new or contested implication. You must find the one statement that directly supports the contested implication — the part labelled "us too" or "also" or "therefore." The three wrong options will each be true but will support a different point, or will talk about the cause rather than the impact.

Best approach: Underline the specific new claim the person is making — the part that could be disputed. Then ask: "Which option directly proves THAT?" Wrong answers typically prove why the general problem exists (recycling rate, durability) or propose a solution (alternatives) rather than proving the impact on the group mentioned.

Question

An environmentalist says: "Plastic pollution in our oceans is not just a problem for the creatures that live there – it affects us too."

Which one of these statements, if true, best supports the environmentalist's claim?

  1. AOnly a small proportion of plastics are recycled.
  2. BMany things made of plastic could be made from environmentally friendly alternatives.
  3. CPlastics are durable and last for over 500 years.
  4. DPlastics have been found in fish sold in supermarkets.

Lesson 10 of 14Strengthening ArgumentsEasy

A politician claims that more trade between countries is better for everyone. The correct supporting statement must show a direct benefit that reaches EVERYONE — not just businesses, not just one country. Option B looks tempting because it links trade to business success, but it only gets you partway: businesses doing better ≠ everyone benefits. Option C is the winner because it connects trade to the absence of war — and war harms literally everyone.

Politician and expert claim questions appear regularly in OC TS and are valued for testing whether students read the claim's scope precisely. The word "everyone" is the key — any option that only benefits a subset (businesses, producers, buyers) cannot be the best support for a claim that says "everyone." Students who miss this word often pick B.

The examiner is testing whether you can match the scope of the claim ("everyone") to the scope of the supporting statement. The correct answer must produce a benefit that is truly universal. An option about businesses only partially supports the claim. An option about war/peace — which affects all people in all countries — is the direct universal match.

A politician or expert makes a broad claim using words like "everyone," "all," or "always." You must find the one supporting statement that directly validates the universal scope of that claim, not just part of it. Wrong answers typically support a narrower version of the claim (e.g. businesses, specific groups) or explain background context rather than the benefit itself.

Best approach: Underline the universal word in the claim — here it is "everyone." Then read each option and ask: "Does this benefit EVERYONE? Or just some people?" Eliminate any option that only benefits a subset. Among what remains, pick the option that creates the most direct causal chain from the thing mentioned in the claim (trade) to the universal benefit.

Question

A politician said in a television interview: “The more trade that countries do with each other, the better it is for everyone.”

Which one of these statements, if true, best supports the politician's claim?

  1. AIt is important for a country to have strong businesses.
  2. BBusinesses do better when more people are buying their goods or services.
  3. CCountries that trade with each other are less likely to go to war against each other.
  4. DDifferent countries can sometimes make particular goods more cheaply than others.

Lesson 11 of 14Strengthening ArgumentsEasy

Here is a deceptively tricky strengthening question — the coach is recommending a physical activity (running or tennis) to improve performance in a mental sport (chess). To find the correct support you need to ask: "What does chess actually need?" Once you identify that chess needs concentration, the answer becomes obvious.

Physical-activity-for-a-mental-skill claims appear regularly in OC TS strengthening questions. They are popular with examiners because one option (Option D here) sounds plausible on the surface but fails to make the leap to the mental game.

The examiner wants to know whether you can identify the logical gap in an argument and then fill it. The gap here is: why would physical exercise help a mental sport? The correct statement bridges that gap by connecting exercise to a mental benefit (concentration). Students who focus on the word "running" instead of the logic of the claim often fall for the distractor about physical strength.

A coach or expert recommends a physical activity to improve performance in a discipline that seems unrelated (e.g. chess, music, exams). You must find the statement that connects the physical activity to the mental or competitive skill involved — not just confirm that the activity is healthy.

Best approach: Identify what the competition actually requires (for chess: concentration, focus, mental endurance). Then ask which option explains why running or tennis would provide that specific ingredient. Reject options that are merely true facts about the activities but do not connect to the target skill.

Question

The school chess coach has told the team that if they want to do well in chess competitions, they should go running or play tennis every day.

Which one of these statements, if true, best supports the coach's claim?

  1. AChess is not a physical sport.
  2. BRegular exercise improves concentration.
  3. CChess players are often good tennis players.
  4. DRunning builds physical strength and stamina.

Lesson 12 of 14Strengthening ArgumentsEasy

Michael dislikes a required book and argues students should choose their own reading. What statement would actually make his case? This is a clean, accessible strengthening question — the answer needs to explain WHY free choice leads to a good outcome, not just that Michael or others are unhappy.

Education or learning policy claims appear regularly in OC TS Strengthening Arguments questions. They are popular because the distractors feel emotionally relevant (others dislike the book too!) while only one option makes the logical case for the claim.

The examiner is testing whether you can identify the logical gap — Michael has a preference, but preference alone is not an argument. The correct support must explain why acting on students' preferences (giving them choice) actually produces a benefit (better learning). The key word is "why" — not "how many people agree" or "what else is similar."

A student or person makes a policy recommendation (e.g. students should have freedom to choose X). You must find the statement that explains why this freedom leads to a positive outcome — not evidence of current dissatisfaction, not a precedent from another context, not an irrelevant preference.

Best approach: Ask: "What would need to be true for Michael's proposal to actually work?" The answer must bridge the gap between "freedom to choose" and a concrete benefit. Option D does this: choice → enjoyment → better learning. Reject options that merely confirm a problem (C) or mention a tangentially related preference (B).

Question

Michael says: "I don't like this book I've been told to read. I think students should be free to choose what books they study at school."

Which one of these statements, if true, best supports Michael's claim?

  1. AStudents are allowed to choose what they study in some other subjects.
  2. BStudents often want to read books that have been made into films.
  3. COther students in the class also disliked the book they were told to read.
  4. DStudents learn more when they enjoy what they read.

Lesson 13 of 14Strengthening ArgumentsIntermediate

Nick wants to learn the Wiradjuri language but thinks it will take a long time. Medika says he should visit Wagga Wagga because there are plenty of Wiradjuri speakers there. Which statement best supports her advice? The trick is identifying the hidden assumption: being around speakers is useful only if speaking with them actually helps you learn.

Language learning recommendation arguments appear in OC TS and Selective exams. They typically have a two-part structure: (1) a place/resource has something relevant, and (2) therefore go there to achieve a goal. The strengthening statement must explain why the resource leads to the goal — not just confirm the resource exists or that the person can access it.

The examiner is testing whether students can spot the gap in Medika's reasoning. Her argument assumes that being near speakers helps learning — but that assumption is never stated. The correct answer (D) fills that gap. Distractor A (travel is easy) only confirms access, not benefit. Distractor C (Medika speaks multiple languages) improves Medika's credibility but doesn't explain the mechanism. Distractor B (language needs hard work) actively works against the suggestion.

Person A has a goal (learn language X). Person B recommends going somewhere or doing something to achieve it (visit a city with many speakers). You must find the statement that explains why Person B's recommendation actually achieves the goal. One distractor confirms access/feasibility, one gives an irrelevant credential to the adviser, one weakens the argument.

Best approach: Ask: what is the goal? (Nick learning Wiradjuri faster.) What is the recommendation? (Go to Wagga Wagga because there are speakers.) What is the missing link? (Why does being near speakers help?) Then scan the options for a statement that fills that gap — it must connect 'speakers present' to 'learning is easier'. Option D does exactly that. Reject options that are about ease of travel (A), general effort required (B), or the adviser's own credentials (C).

Question

Nick wants to learn to speak the Wiradjuri language, but he thinks it will take him a long time. Medika suggests a solution: "You should spend some time in Wagga Wagga. There are plenty of people there who can speak Wiradjuri."

Which one of these statements, if true, best supports Medika's claim?

  1. ANick can travel to Wagga Wagga fairly easily.
  2. BLearning a language always takes hard work and concentration.
  3. CMedika has learned to speak three different languages.
  4. DLanguages are easier to learn if you practise speaking them with other people.

Lesson 14 of 14Strengthening ArgumentsIntermediate

A gardener says talking to plants is a good idea — because you're more likely to remember to water them if you treat them like friends. Which statement best supports this? The answer explains the mechanism: when you talk to a plant, you naturally pay close attention to it and notice what it needs — including whether it's thirsty.

Mechanism-filling strengthening questions — where the claim has an implicit gap about HOW something works — appear regularly in OC TS. The gardener's argument states the outcome (you remember to water) but not the why. The correct supporting statement fills that causal gap. Students who confuse "adds some general benefit" with "explains the specific mechanism" will often choose D (old tradition) or B (plants understand) and miss A.

The examiner is testing whether students can identify the unstated assumption in the gardener's reasoning and find the option that fills it. The argument's implicit gap is: why does treating a plant like a friend lead to better watering? Option A fills this gap (you pay closer attention → notice health details → respond to watering needs). Option C is a deliberate weakener disguised as a factual-sounding statement — students who misread it as neutral often pick it.

A person makes a recommendation and gives a reason (X is a good idea because it leads to outcome Y). The reason relies on an unstated mechanism (HOW does X lead to Y?). The correct strengthening statement provides that mechanism. Distractor options will: (1) give an irrelevant benefit of X, (2) undermine the claim, (3) state a historical fact about X that doesn't prove its value.

Best approach: Underline the specific outcome in the claim: 'more likely to remember to water them.' Then ask: which option explains WHY talking to a plant would make you water it more reliably? Option A says you notice health details while talking — drooping leaves, dry soil — which directly prompts watering. That's the mechanism. Reject B (plants understanding is irrelevant to the gardener's memory), C (actively weakens), and D (age/tradition ≠ effectiveness).

Question

A gardener is giving advice about taking care of plants. He says: "Some people think talking to plants is strange, but it's actually a really good idea. After all, you're more likely to remember to water them if you treat them like friends!"

Which one of these statements, if true, best supports the gardener's claim?

  1. APeople often notice details about a plant's health when they are talking to it.
  2. BSome people believe that plants can understand what people say to them.
  3. CTalking to plants won't help people avoid overwatering them.
  4. DTalking to plants is a very old tradition.
