Syllogism

Q: Statements: All Apples are Mangoes. All Mangoes are Bananas. Conclusions: I. All Apples are Bananas. II. Some Mangoes are Apples.

Correct Answer: Option C (Both conclusions I and II follow). Since all Apples are inside Mangoes and all Mangoes are inside Bananas, all Apples are definitely Bananas. Also, since all Apples are Mangoes, the intersection implies some Mangoes are Apples. Both follow.

Q: Statements: Some Shirts are Pants. All Pants are Shoes. Conclusions: I. Some Shirts are Shoes. II. All Shirts are Shoes.

Correct Answer: Option A (Only conclusion I follows). Since some Shirts are Pants and all Pants are Shoes, the overlapping part of Shirts must also be Shoes. Hence some Shirts are Shoes. We cannot definitively say all Shirts are Shoes. Only I follows.

Q: Statements: All Doctors are Engineers. No Engineers is Teachers. Conclusions: I. No Doctors is Teachers. II. Some Engineers are Doctors.

Correct Answer: Option C (Both conclusions I and II follow). Since all Doctors are inside Engineers, and Engineers has no intersection with Teachers, Doctors cannot intersect Teachers. Also, all Doctors are Engineers implies some Engineers are Doctors. Both follow.

Q: Statements: Some Rivers are Lakes. No Lakes is Oceans. Conclusions: I. Some Rivers are not Oceans. II. No Rivers is Oceans.

Correct Answer: Option A (Only conclusion I follows). The part of Rivers that overlaps with Lakes cannot be Oceans. Hence some Rivers are not Oceans. We cannot conclude that no Rivers is Oceans entirely. Only I follows.

Q: Statements: All Cats are Dogs. Some Dogs are Rats. Conclusions: I. Some Cats are Rats. II. Some Rats are Dogs.

Correct Answer: Option B (Only conclusion II follows). We know some Dogs are Rats, which directly implies some Rats are Dogs. However, the intersection of Dogs and Rats might not touch Cats. Hence I does not follow. Only II follows.
