The breakdown

  • Additional Evidence: Strengthening and weakening arguments with new information.
  • Matching Arguments: Recognising argument structures that are parallel or equivalent.
  • Identifying Similarity: Pattern and structure comparison across cases.
  • Syllogisms: Applying categorical logic and valid inference forms.
  • Evaluating Hypotheses: Assessing whether evidence supports or undermines a hypothesis.
  • Data Sufficiency: Deciding if given information is enough to answer the question.

Question 1 · Multiple choice

Question

In a group of students, everyone who likes maths also likes science. No one who likes art likes maths. Bella likes science.

Options

Which of the following must be true?

  • A.Bella likes maths.
  • B.None of the above must be true.
  • C.Bella likes art.
  • D.Bella does not like maths.

Correct answer

B.None of the above must be true.

Explanation

The rules are: maths → science, and art → not maths.

From "Bella likes science" alone, we cannot conclude she likes maths. The rule says maths people like science — but other students can also like science without liking maths. Concluding maths from science is a converse error. Option A is wrong.

We also cannot conclude anything about whether Bella likes art (Option C) or does not like maths (Option D) — there is simply not enough information either way.

None of A, C, or D must be true.

Final answer: Option B (None of the above must be true).

Question 2 · Multiple choice

Question

A net of a cube is shown below.

Which of the following could be a possible view of the cube?

Cube net with letters A–F and four labelled 3D views (options A–D)

Options

  • A.A
  • B.B
  • C.C
  • D.D

Correct answer

C.C

Explanation

Look for the pairs that sit on opposite sides.

For this type of net, the pairs of opposite faces are:

  • A and C
  • B and E
  • D and F

Opposite face pairs when the net is folded into a cube

It is impossible to see opposite faces in a single view. That means any view that shows a pair of opposite faces cannot be a possible view.

  • Option A shows opposite faces D and F together, so it cannot be correct.
  • Option B shows opposite faces A and C together, so it cannot be correct.

That rules out Options A and B.

Now look at Option D. It shows the flat part of letter D connected with the flat part of letter E like this:

Why Option D does not match how D and E meet in the net

However, in the given net, the bottom (straight side) of letter D connects with the top of letter E along their shared edge:

How D meets E along the shared edge in the net

Therefore, Option D can also be ruled out.

That leaves Option C as the only possible view of the cube.
