Three statements are given followed by three conclusions numbered I, II, and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
Some dogs are animals.
Some animals are pet.
All pets are white.
Conclusions:
I. Some dogs are white.
II. Some animals are white.
III. Some animals are dogs.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Only conclusions II and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some dogs are white → False (It is possible, but no definite conclusion can be drawn).
II. Some animals are white → True (As some animals are pets, and all pets are white so, some animals are white).
III. Some animals are dogs → True (As some dogs are animals, so the reverse of some animals are dogs is also true).
