Question: 1

In each question below are given two statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance from commonly known facts.
Statements :
I. Some nurses are nuns.
II. Madhu is a nun.
Conclusions :
I. Some nuns are nurses.
II. Some nurses are not nuns.

(A) If only conclusion I follows

(B) If only conclusion II follows

(C) If either I or II follows

(D) If neither I nor II follows and

(E) If both I and II follow

Ans: D

Since the middle term is not distributed even once in the premises, so no conclusion follows.

Question: 2

II. All dogs are not birds.

(A) If only conclusion I follows

(B) If only conclusion II follows

(C) If either I or II follows

(D) If neither I nor II follows and

(A) If only conclusion I follows

(B) If only conclusion II follows

(C) If either I or II follows

(D) If neither I nor II follows and
