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 deer are snakes.
All deer are tigers.
Some wolves are deer.
Conclusions:
I. Some tigers are not deer.
II. Some deer are wolves.
III. Some tigers are snakes.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only conclusions II and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some tigers are not deer → False (It is possible, but no definite conclusion can be drawn.)
II. Some deer are wolves → True (As some wolves are deer, so, some deer are wolves is also true.)
III. Some tigers are snakes → True (As some snakes are deer, and all deer are tigers, so, some tigers are snakes is also true.)
Hence, Only conclusions II and III follow.
