Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
All wires are cables.
All wires are ropes.
Some ropes are steel.
Conclusions
(I) Some steels are wires.
(II) Some ropes are cables.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2, i.e., Only conclusion (II) follows.
Conclusions
(I) Some steels are wires → Does not follow (In statement nothing says that any steel is a wire — we only know that some ropes are steel, and all wires are ropes, not vice versa. This does not logically follow.)
(II) Some ropes are cables → Follows (Wires are a common part of both ropes and cables. That means: the intersection of ropes and cables includes at least all wires.)
