Sample Questions from Test 14

The first two questions of this mock test (same order and wording as the timed exam).

Thinking Skills

If Emma forgets to charge her phone overnight, she is likely to have a dead battery by noon.

Question 1 · Multiple choice

Question

If Emma forgets to charge her phone overnight, she is likely to have a dead battery by noon.

If she has a dead battery, she will use her school laptop instead.

If she uses her school laptop, she might not complete all her homework.

Options

If the statements are correct, which one of the following is NOT possible?

  • A.Emma forgets to charge her phone overnight and does not have a dead battery by noon.
  • B.Emma has a dead battery and does not use her school laptop.
  • C.Emma uses her school laptop and completes all her homework.
  • D.Emma completes all her homework without using her school laptop.

Correct answer

B.Emma has a dead battery and does not use her school laptop.

Explanation

Step 1 — Understand each rule's strength.

Rule 1: Forget to charge → LIKELY dead battery by noon
         (not certain — "likely" allows for exceptions)

Rule 2: Dead battery → WILL use school laptop
         (certain — "will" means definite)

Rule 3: Uses school laptop → MIGHT NOT complete all homework
         (not certain — "might not" allows she still could complete it)

Step 2 — Find what is NOT POSSIBLE.

"NOT possible" means: what CAN NEVER happen?

Look at Rule 2: "If she has a dead battery, she WILL use her school laptop." "Will" is a definite guarantee — there are no exceptions.

So if Emma has a dead battery, she DEFINITELY uses the school laptop.

The opposite — Emma has a dead battery but does NOT use the school laptop — CANNOT HAPPEN.

Step 3 — Check option B.

"Emma has a dead battery and does not use her school laptop."

This contradicts Rule 2 directly. If dead battery → will use laptop. There is no way she can have a dead battery AND not use the laptop. This is NOT possible. ✓

Answer: B — Emma has a dead battery and does not use her school laptop (this is NOT possible)

Thinking Skills

"Painting a perfect portrait requires precision, patience and expertise."

Question 2 · Multiple choice

Question

"Painting a perfect portrait requires precision, patience and expertise."

Tara: "I never use any reference images when I paint, and I always look at the final piece myself to decide if the portrait looks right."

Options

If the statements are correct, which one of the following is NOT possible?

  • A.Painting a perfect portrait is easy for Tara.
  • B.Tara does not often paint a perfect portrait due to her lack of precision.
  • C.Tara likes to paint in her spare time.
  • D.Tara has a lot of expertise in painting portraits.

Correct answer

B.Tara does not often paint a perfect portrait due to her lack of precision.

Explanation

Step 1 — Understand the rule

"Painting a perfect portrait requires precision, patience and expertise."

Rule: Perfect portrait → precision + patience + expertise (all three are required)

Step 2 — Understand Tara's approach

Tara says:

  • She never uses reference images when she paints.
  • She looks at the final piece herself to judge whether it looks right.

This tells us HOW she works — but it does NOT say she definitely lacks precision. She might be naturally precise, or precise through practice.

Step 3 — Identify what CANNOT be concluded

Option B says: "Tara does not often paint a perfect portrait due to her lack of precision."

This makes TWO claims:

  1. Tara doesn't often paint perfect portraits.

  2. The REASON is her lack of precision.

The second part is the problem. The information only describes her method (no references, judges by eye). It does not prove she definitely lacks precision. A person who never uses reference images could still be very precise through experience or natural skill.

We CANNOT conclude from the given information that she specifically lacks precision as a definite fact. This specific causal claim is not possible to establish from what we know.

Answer: B — "Tara does not often paint a perfect portrait due to her lack of precision" (this conclusion cannot be established)
