Three statements are given followed by two conclusions numbered I and II. 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:
All birds are crows.
Some crows are parrots.
No crow is a pigeon.
Conclusions:
I. No parrot is a pigeon.
II. Some birds are parrots.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Neither conclusion I nor II follows.
The least possible diagram is:
Conclusions:
I. No parrot is a pigeon → Does not follow (This conclusion does not follow as there is no definite relation between parrot and pigeon.)
II. Some birds are parrots → Does not follow (This conclusion also does not follow as there is no definite relation between parrot and birds.)
Hence, the correct answer is neither conclusion I nor II follows.
