In the question below, two statements followed by two conclusions numbered I and II are given. You have to take the two given statements to be true even if they seem to be at variance of commonly known facts and decide which of the conclusion(s) logically follow(s) from the two given statements, disregarding commonly known facts.
Statements :Some books are papers. Some papers are notebooks.
Conclusions :
I. Some papers are books.
II. Some notebooks are papers.

AOnly conclusion I follows
BOnly conclusion II follows
CNeither I nor II follows
DBoth I and II follow


It should be 'A' as we can infer 3 points from the statements. 1) Some books are papers, 2) Some papers are notebooks and 3) Some papers are books. But it not given that only some of the notebooks are paper, it might also be that all notebooks are papers. So according to this, it should be 'A'.
