  • Finding Procedures: Identifying the correct sequence or steps to reach an outcome.
  • Additional Evidence: Strengthening and weakening arguments with new information.
  • Spatial Reasoning: Visualising and manipulating shapes, positions, and arrangements.
  • Seating Arrangements: Deducing who sits where from ordering and constraint clues.
  • Drawing a Conclusion: Logic-based deduction and inference from given premises.

Sample Questions from Test 15

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

Thinking Skills

Rina, Sam, and Tia collect trading cards.

Question 1 · Multiple choice

Question

Rina, Sam, and Tia collect trading cards.

  • Rina has: stars, moons, suns, comets, dots.
  • Sam has: cats, dots, comets.
  • Tia has: moons, parrots, comets, dots, ants.

Options

Which card do exactly two of the three collectors have?

  • A.comets
  • B.moons
  • C.dots
  • D.stars

Correct answer

B.moons

Explanation

Step 1 — List every card each person has.

  • Rina: stars, moons, suns, comets, dots
  • Sam: cats, dots, comets
  • Tia: moons, parrots, comets, dots, ants

Step 2 — Count how many collectors own each option.

  • comets → Rina ✓, Sam ✓, Tia ✓ → all three ✗
  • moons → Rina ✓, Sam ✗, Tia ✓ → exactly two ✓
  • dots → Rina ✓, Sam ✓, Tia ✓ → all three ✗
  • stars → Rina ✓, Sam ✗, Tia ✗ → only one ✗

Only moons is held by exactly two collectors (Rina and Tia).

Thinking Skills

Three views of a cube are shown below. Which number is on the opposite side of 1?

Question 2 · Multiple choice

Question

Three views of a cube are shown below. Which number is on the opposite side of 1?

Three isometric views of the same cube with numbered faces. View 1: 2 on top, 1 on front, 4 on right. View 2: 4 on top, 1 on front, 3 on right. View 3: 5 on top, 4 on front, 3 on right.

Options

  • A.6
  • B.2
  • C.5
  • D.4

Correct answer

C.5

Explanation

Face 1 stays on the front in both Views 1 and 2, so the cube was rolled around the front-back axis between those views.

Rolling 90° to the left (the right face moves to the top):

  • Old right (4) → new top ✓ (matches View 2 top = 4)
  • Old top (2) → new left
  • Old bottom → new right (= 3, matching View 2 right)

So in View 1: top = 2, bottom = 3 → these are opposite faces. Pair: (2, 3).

The six faces are 1–6. The remaining four faces — 1, 4, 5, 6 — form two more pairs. We can rule out pairings using the views:

  • (1, 4) impossible: faces 1 and 4 appear on perpendicular sides in Views 1 and 2, so they cannot be opposite.
  • (4, 5) impossible: faces 4 and 5 appear on perpendicular sides in View 3, so they cannot be opposite.

The only valid pairings left are (1, 5) and (4, 6).

The face opposite 1 is 5 → answer C.

  • A (6): opposite 4. ✗
  • B (2): opposite 3. ✗
  • C (5): opposite 1. ✓
  • D (4): opposite 6. ✗
