Question 1

In a logical diagram, all Circles are Squares, and all Squares are Triangles. Which must be true?

Accepted Answer

All Circles are Triangles.

Answer

If Circles ⊂ Squares and Squares ⊂ Triangles, then by transitivity Circles ⊂ Triangles.

Question 2

The series: 2, 5, 10, 17, 26, ___. What comes next?

Accepted Answer

37

Answer

Differences are 3, 5, 7, 9, 11 — odd numbers increasing by 2; so 26 + 11 = 37.

Question 3

A manager states: 'If project costs exceed budget, approval is required.' Costs did not exceed budget. What follows?

Accepted Answer

No conclusion can be drawn about approval.

Answer

The conditional only guarantees approval when costs exceed budget; the converse is not necessarily true.

Question 4

Five tasks are ranked 1–5 by priority. Task B is higher priority than Task D. Task A is lower priority than Task C. Task C is higher priority than Task B. Which task has the highest priority?

Accepted Answer

Task C

Answer

The chain is C > B > D and C > A, making C the highest among all mentioned tasks.

Question 5

Which argument structure is an example of 'affirming the consequent' (a logical fallacy)?

Accepted Answer

If P then Q; Q is true; therefore P.

Answer

Affirming the consequent incorrectly concludes P from Q when the conditional is P→Q.
