Sample Questions from Test 10

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

Thinking Skills

If Sienna does not eat nutritious food, she is likely to be tired during her race.

Question 1 · Multiple choice

Question

If Sienna does not eat nutritious food, she is likely to be tired during her race. If she is tired, she may not win first place. If she wins first place, she will win a trophy.

Options

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

  • A.Sienna ate nutritious food and won a trophy.
  • B.She ate nutritious food but did not win a trophy.
  • C.She came first place but did not get a trophy.
  • D.Sienna was tired during the race but still won a trophy.

Correct answer

C.She came first place but did not get a trophy.

Explanation

Step 1 — Map out the rules and their strength.

Rule 1: Does NOT eat nutritious food  →  LIKELY tired  (probable, not certain)
Rule 2: Tired                         →  MAY not win first place  (possible, not certain)
Rule 3: Wins first place              →  WILL win trophy  (definite — no exceptions)

Step 2 — Find what is NOT POSSIBLE.

Rule 3 is the ONLY definite rule: if she wins first place, she WILL win a trophy. There are no exceptions.

This means: it is IMPOSSIBLE for her to win first place without winning a trophy.

Step 3 — Check option C.

"She came first place but did not get a trophy."

This directly contradicts Rule 3 (which says first place = WILL win trophy). If she came first, the trophy is guaranteed. She CANNOT come first without getting a trophy.

Answer: C — She came first place but did not get a trophy (this is NOT possible)

Thinking Skills

Prices of tolls on the freeway have increased to encourage drivers to take other types of transport. This is …

Question 2 · Multiple choice

Question

Prices of tolls on the freeway have increased to encourage drivers to take other types of transport. This is to reduce road congestion. If more people are travelling on trains and buses, it will lead to a more sustainable future because less fossil fuels will be consumed.

Options

Which of the following can be assumed?

  • A.The environment will benefit from a lower amount of road pollution.
  • B.There will be more cars on the road due to the increased price of tolls.
  • C.The price of the tolls will decrease to encourage travelling by car.
  • D.Drivers who do not believe that road pollution is high will continue to drive.

Correct answer

A.The environment will benefit from a lower amount of road pollution.

Explanation

The argument's chain:

Higher tolls → Fewer drivers → Fewer cars → Less fossil fuels → More sustainable future

What is being ASSUMED (but not stated) in the passage?

The passage says "less fossil fuels will be consumed" and this leads to a "more sustainable future." But there's an unstated link: why is less fossil fuel good for the future?

The missing assumption is: less fossil fuel consumption means less road pollution, and that benefits the environment.

The passage never explicitly says this — it just assumes that the environment benefits from less road pollution as part of its chain of reasoning.

Answer: A — The environment will benefit from a lower amount of road pollution
