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.
