Mathematical Reasoning · Sample 1

A bag contains 3 red, 4 blue, and 5 green marbles. If one marble is chosen at random, what is the probability it is NOT red?

  • A. 1/4
  • B. 3/4
  • C. 1/3
  • D. 2/3
Show answer & explanation

Answer: B — 3/4

There are 12 marbles total. Non-red = 4 + 5 = 9. Probability = 9/12 = 3/4.

Reading · Sample 2

The lyrebird is one of Australia's most remarkable birds. Males can mimic almost any sound they hear — from chainsaws to camera shutters to other birds' calls. This ability evolved to attract mates, not to entertain humans.

According to the passage, why did the lyrebird develop its mimicry ability?

  • A. To entertain other animals in the forest
  • B. To warn other birds of predators
  • C. To attract a mate
  • D. To communicate with humans
Show answer & explanation

Answer: C — To attract a mate

The passage explicitly states "This ability evolved to attract mates."

Thinking Skills · Sample 3

Which number comes next in the sequence? 2, 6, 12, 20, 30, __

  • A. 38
  • B. 40
  • C. 42
  • D. 44
Show answer & explanation

Answer: C — 42

Differences are +4, +6, +8, +10, +12. Next term = 30 + 12 = 42.

Thinking Skills · Sample 4

If all Blips are Glops, and some Glops are Flips, which statement MUST be true?

  • A. All Blips are Flips
  • B. Some Blips might be Flips
  • C. No Blips are Flips
  • D. All Flips are Blips
Show answer & explanation

Answer: B — Some Blips might be Flips

Since all Blips are Glops, and some Glops are Flips, it's possible (but not certain) that some Blips are also Flips.
