Question

Identify the set of three statements that are logically related.
A. All roses have thorns.
B. All roses have nectar.
C. All plants with nectar have thorns.
D. All shrubs have roses.
E. All shrubs have nectar.
F. Some roses have thorns.

• A. BEF
• B. BCF
• C. BDE
• D. ACF

Hint:

In syllogism-type problems, universal statements (All X are Y) automatically imply corresponding particular statements (Some X are Y).

Answer 1

The Correct Option is D

A — "All roses have thorns." — This is a universal statement establishing a general property of roses.
C — "All plants with nectar have thorns." — This is another universal statement linking nectar to the presence of thorns.
F — "Some roses have thorns." — This is a particular statement which follows logically from A, because if all roses have thorns, it must also be true that some roses have thorns.
These three — A, C, F — are logically connected:
1. A and C are universal premises.
2. F is a particular conclusion supported by A.
Thus, ACF forms a consistent and logically connected set.
