Question

Choose the set of three statements which are most logically related:
Statements:
A. Some mammals are carnivores.
B. All whales are mammals.
C. All whales are aquatic animals.
D. All whales are carnivores.
E. Some aquatic animals are mammals.
F. Some mammals are whales.

• A.
• B.
• C.
• D.

Hint:

When two universal statements overlap in a category, they often imply a valid “some” statement linking the outer categories.

Answer 1

The Correct Option is D

Choose B (“All whales are mammals”), C (“All whales are aquatic animals”), and E (“Some aquatic animals are mammals”):
- From B and C, whales are both mammals and aquatic animals.
- This means at least some aquatic animals (whales) are mammals, which is exactly what E states.
Thus, B and C together logically imply E.
This set avoids unnecessary specific dietary statements like carnivores, which would introduce extra constraints not supported by the chain.
