Question

Write the characteristics of a big book

Answer 1

<<This question is answered considering that the book in question is any book and not any specific book.>>

The characteristics of a big book are:

*It might be big in terms of length or breadth. A book that has more pages than a usual book is a big book. In both cases, such a big book is very likely to be difficult to comfortably hold and read.

*It will be of the normal size but there will be more content than in standard books. This means that the time taken to finish reading the book will be more.

Answer 2

Well, this question is not clear enough.
But a big book usually contains more number of pages and content than the normal one.
A big book may be heavy in weight which can make it difficult to handle. A big book is difficult to carry than smaller books.
Completely reading a big book takes alot more time as compared to normal books. Similarly, more time is needed to write a big book. 

hope this will help you.
