1. Statements All rings are birds. Some birds are cages. All cages are kites. Conclusions I. All kites are cages II. Some kites are rings III. Some birds are kites

Only I follows

Only II follows

Only III follows

I and II follows

None of these

The conclusion "Only III follows" is the correct answer because it is supported by the given statements. The statements state that all cages are kites, and some birds are cages. Therefore, it can be concluded that some birds are also kites. However, there is no information provided to support the conclusions "All kites are cages" or "Some kites are rings."

Explanation

The conclusion "Only III follows" is the correct answer because it is supported by the given statements. The statements state that all cages are kites, and some birds are cages. Therefore, it can be concluded that some birds are also kites. However, there is no information provided to support the conclusions "All kites are cages" or "Some kites are rings."

2. Statements Some reds are crows. All crows are yellows. All yellows are rabbits. Conclusions I. All crows are rabbits. II. Some yellows are reds. III. Some reds are rabbits.

All follows

Only I follows

I and II follows

Either I or II follows

None follows

The given statements establish that there is an overlap between reds and crows, and between crows and yellows. Since all yellows are rabbits, it can be concluded that all crows (which include the reds) are also rabbits. This validates the first conclusion. Additionally, since some reds are crows and all crows are yellows, it can be inferred that some yellows are reds, supporting the second conclusion. Finally, since some reds are crows and all crows are rabbits, it can be deduced that some reds are also rabbits, confirming the third conclusion. Therefore, all the conclusions can be derived from the given statements.

3. Statements Some dogs are bags. No bag is lion. All rooms are lions. Conclusions I. Some rooms are bags. II. Some dogs are lions. III. Some rooms are dogs

All follows

Only I follows

Only II follows

Only III follows

None of these

None of the conclusions can be inferred from the given statements. The statements only provide information about the relationship between dogs, bags, lions, and rooms, but they do not establish any direct connection between them. Therefore, we cannot conclude that some rooms are bags (conclusion I), some dogs are lions (conclusion II), or some rooms are dogs (conclusion III). Hence, the correct answer is "None of these".

Explanation

None of the conclusions can be inferred from the given statements. The statements only provide information about the relationship between dogs, bags, lions, and rooms, but they do not establish any direct connection between them. Therefore, we cannot conclude that some rooms are bags (conclusion I), some dogs are lions (conclusion II), or some rooms are dogs (conclusion III). Hence, the correct answer is "None of these".

4. Statements Some trees are lions. Some lions are cows. All cows are bats. Conclusions I. Some bats are trees II. Some cows are trees. III. No bat is tree.

None follows

Only III follows

Only II follows

Either I or III follows

None of these

Either I or III follows. This is because from the given statements, we can conclude that some bats are trees (I) and no bat is a tree (III). Both conclusions can be logically derived from the given statements.

Explanation

Either I or III follows. This is because from the given statements, we can conclude that some bats are trees (I) and no bat is a tree (III). Both conclusions can be logically derived from the given statements.

5. Statements All pens are grasshoppers. Some grasshoppers are clouds. Some clouds are bottles. Conclusions I. Some bottles are grasshoppers. II. Some clouds are pens. III. No pen is cloud.

Only III follows

Either II or III follows

Only II follows

Either I and II follows

None of these

Based on the given statements, we can conclude that some clouds are pens (II) and that no pen is a cloud (III). Therefore, either II or III follows.

Explanation

Based on the given statements, we can conclude that some clouds are pens (II) and that no pen is a cloud (III). Therefore, either II or III follows.
