Directions : In each of the following questions a statement is given, followed by three conclusions. Give answer :

Statement: This book is so prepared that even a layman can study science in the absence of a teacher.

Assumptions :
I. A layman wishes to study science without a teacher.
II. A teacher may not always be available to teach science.
III. A layman generally finds it difficult to learn science on its own.

Explanation:-

Clearly, the statement is made to impress the usefulness of the book. It does not mention the desire of a layman. So, I is not implicit. Also, the book is intended to guide one when a teacher is not available. So, both II and III are implicit.
