You might think that this implies that some boxes are books, but this conclusion requires the knowledge that some books exist, and so doesn't follow from the original two statements alone. Hence the question is technically flawed, but choice (C) is the intended answer.

All pages are boxes

It means books = pages = boxes.

So only one circle will be formed. Why did you draw 3 circles?

It is important to note that 'are' != '='

 May 14th, 2018, 07:34 PM #7 Senior Member   Joined: Aug 2014 From: India Posts: 310 Thanks: 1 I found the shortcut, which you guys failed to give me. All books are pages All pages are boxes Second sentence ends with boxes so outer circle will contains boxes. Second sentence starts with pages and First sentence ends with pages, so first inner circle will contains pages First sentence starts with books, so second inner circle is marked with books.
