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:
Only a few ladders are walls.
Some ladders are vans.
All vans are cans.
Conclusions:
I. Some cans are ladders.
II. All walls being cans is a possibility.
III. No vans can be walls.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1, i.e., both conclusions I and II follow.
Conclusions:
I.Some cans are ladders → Follows (Some ladders are vans. All vans are cans. So, the ladders that are vans must also be cans)
II. All walls being cans is a possibility → Follows (Only a few ladders are walls' gives a partial link between ladders and walls. However, walls and cans are not directly linked, and no contradiction arises if all walls turn out to be cans. Since nothing rules this out, and it's a possibility,)
III. No vans can be walls → Does not follow (The statements do not say vans and walls are mutually exclusive.)
