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:
All trees are rocks.
All rocks are cups.
Conclusions:
I. All trees are cups.
II. Some cups are trees.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Both conclusions I and II follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All trees are cups → True (As all trees are rocks and all rocks are cups, so all trees are cups is also true.)
II. Some cups are trees → True (As all trees are rocks, and all rocks are cups, so, some cups are trees is also true.)
Hence, Both conclusions I and II follow.
