Directions: Three 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:
I: No bridge is a mountain.
II: Some mountains are monuments.
III: All monuments are harbors.
Conclusions:
I: Some harbors are mountains.
II: No bridge is a monument.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Only conclusion I follows.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some harbors are mountains → True (As some mountains are monuments, and, all monuments are harbors, so, some harbors are mountains is true.)
II. No bridge is a monument → False (It is possible, but no definite conclusion can be drawn.)
Hence, the correct answer is option 4.
