Test: Syllogism - 1 - Question 1

Two 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:

Some horses are not trucks.

All horses are white.

Conclusions:

I. Some white are trucks.

II. Some horses being truck is a possibility.

II. Some horses being truck is a possibility. → Follows (As, some horses are trucks is not definite, but it can be possible)

 Hence, the correct answer is "Only conclusion II follows".

Test: Syllogism - 1 - Question 2
