In the following question below are given some statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows the given statements.

Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Only conclusion I follows.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some weak are men → True (As some men are weak, so, some weak are men is also true.)
II. All strong are men → False (As no weak is strong, so, no positive conclusions can be made.)
III. Some strong are weak → False (As no weak is strong, so, no strong are weak.)
Hence, Only conclusion I follows.
