Two statements are followed by two conclusions. Assume the facts in the statements to be true and decide which of the conclusions follow(s) from the statements.
Statements:
I. Some papers are books
II. All books are notes.
Conclusions:
I. No paper is a note
II. Some notes are papers

Statements:
I. Some papers are books
II. All books are notes.

​Conclusions:
I. No paper is a note

From the statements, some "papers" are "books," and all "books" are "notes."
Therefore, some "papers" (the ones that are "books") are also "notes." Hence, this conclusion does not follow.
II. Some notes are papers​​​

From the statements, some "papers" are "books," and all "books" are "notes."
Therefore, there is an overlap between "papers" and "notes." Hence, this conclusion follows.​​

Thus, the correct option (b) Only conclusion II follows.
