Sample Questions from Test 2

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

Thinking Skills

This 3D shape was built using small blocks.

Question 1 · Multiple choice

Question

This 3D shape was built using small blocks.

Choose the back view of the 3D shape.

Isometric block solid with FRONT arrow and four back-view silhouettes labelled A to D

Options

  • A.A
  • B.B
  • C.C
  • D.D

Correct answer

D.D

Explanation

The FRONT arrow shows which side is the front. The back is the opposite side — imagine walking around the shape (or spinning it in your head) until you face that side. The back view is the flat “stair-step” outline you see from there: one bump for each column, as tall as that column goes. Compare A, B, C, and D. D is the only picture where every bump is the right height in the right order for the back. The others mix up heights, use too few columns, or show a tower too short or too tall.

Thinking Skills

On a standard die, opposite faces always add to 7.

Question 2 · Multiple choice

Question

On a standard die, opposite faces always add to 7.

Options

Which pair of numbers could not appear on adjacent faces (sharing an edge) of a real standard die?

  • A.2 and 4
  • B.1 and 3
  • C.3 and 4
  • D.5 and 6

Correct answer

C.3 and 4

Explanation

On a standard die, opposite faces always add to 7.

Opposite pairs on a standard die:
  1  ←──────→  6   (1 + 6 = 7)
  2  ←──────→  5   (2 + 5 = 7)
  3  ←──────→  4   (3 + 4 = 7)

Opposite faces point directly away from each other — they can never share an edge (be adjacent).

Key fact: Every other pair of faces (that is NOT an opposite pair) CAN be adjacent.

Check each option.

  • 2 and 4 → 2 is opposite 5, and 4 is opposite 3. Neither is the other's opposite partner, so these two CAN be adjacent. ✗
  • 1 and 3 → 1 is opposite 6, and 3 is opposite 4. Same reason — they CAN be adjacent. ✗
  • 3 and 4 ✓ → 3 and 4 ARE an opposite pair (3 + 4 = 7). They face directly away from each other and can never share an edge.
  • 5 and 6 → 5 is opposite 2, and 6 is opposite 1. They CAN be adjacent. ✗

Answer: 3 and 4
