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:
All flowers are leaves.
All leaves are stems.
Some stems are roots.
Conclusions:
I. Some stems are leaves.
II. Some flowers are roots.
III. Some leaves are flowers.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Only conclusions I and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some stems are leaves → True (As all leaves are stems, so, some stems are leaves is also true.)
II. Some flowers are roots → False (It is possible, but no definite conclusion can be drawn.)
III. Some leaves are flowers → True (As all flowers are leaves, so, some leaves are flowers is also true.)
Hence, Only conclusions I and III follow.
