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

Assumptions:

  1. A layman wishes to study science without a teacher.
  2. A teacher may not always be available to teach science.
  3. A layman generally finds it difficult to learn science on its own.

[A]. Only I and II are implicit
[B]. Only II and III are implicit
[C]. Only I and III are implicit
[D]. All are implicit
[E]. None of these

Answer: Option B

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.
