Question 121

# Four 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 given conclusions logically follow(s) from the statements.Statements:1. Some sheds are caves.2. All sheds are nests.3. Only a few nests are stables.4. Some sheds are dens.Conclusions:I. Some caves are nests.II. No shed is stable.

Solution

From statement 1, we know that there is at least some overlap between sheds and caves. From statement 2, we know that all sheds are nests, so the overlap between sheds and caves must also be within the category of nests. Statement 4 confirms that there is an overlap between sheds and dens, but since all sheds are nests, this also implies an overlap between nests and dens.

Conclusion I: Some caves are nests. This conclusion logically follows from the given statements. Since some sheds are caves and all sheds are nests, it's logical to conclude that some caves are nests. So, Conclusion I is true.

Conclusion II: No shed is stable. This conclusion does not logically follow from the given statements. Statement 3 states that only a few nests are stables, but it doesn't exclude the possibility that some sheds might also be stables. Therefore, we cannot conclude that no shed is stable based on the given statements. So, Conclusion II is false.

Therefore, Conclusion I logically follows from the given statements, but Conclusion II does not.

The correct option is A
