Question

Identify the set of three statements that are logically related.
A. Some abra are dabra.
B. All abra are cabra.
C. All dabra are abra.
D. All dabra are not abra.
E. Some cabra are abra.
F. Some cabra are dabra.

• A. AEF
• B. BCF
• C. ABD
• D. BCE

Hint:

When three statements each connect two of the same three terms, they often form a valid logical grouping for these types of questions.

Answer 1

The Correct Option is A

A — "Some abra are dabra." — This is a particular positive statement linking abra and dabra.
E — "Some cabra are abra." — This links cabra and abra with a particular relationship, partially overlapping their sets.
F — "Some cabra are dabra." — This links cabra and dabra. When combined with A and E, it builds a triangular relationship among the three categories abra, dabra, and cabra.
These three statements together form a logically related set because they can be mapped on a Venn diagram and connected via shared terms to make possible inferences.
