This book is _________ cheap, but also useful.

a)As well as
b)Not only
c)Both
d)As

Answer 1

Hint: Conjunction is a word that is used to connect two or more clauses or sentences or to coordinate words in the same clause.

Complete step-by-step answer:
Let us analyze the given conjunctions in the options:
Option (a.), 'as well as', refers to 'in addition’ or ‘also'.
For example- 'The book is cheap as well as useful'.
However, this sentence uses the phrase 'but also' and hence, we can't use 'as well as' over here.
Thus, option (a.) is incorrect.
Option (c.), 'both', refers to two people or things.
 For example- 'Both Laksh and Lakshmi were happy.'
'Both' is often used with the word 'and'.
As the given sentence has the phrase 'but also', we can't use the word 'both' here.
Thus, option (c.) is incorrect.
Option (d.), ‘as', is used to explain any reason(s) in a sentence.
For example- 'I didn't go to college as I was sick.'
Since the given sentence doesn't have any reason, we can't use the word 'as' here. Thus, option (d.) is incorrect.
Option (b.), ‘not only' is used to explain that something is not limited, and there is more in the given sentence.
'Not only-but also' are often used together in sentences. Since the given sentence has 'but also' we can use 'not only' here.
Thus, option (b.) is the correct answer.
'This book is not only cheap but also useful.'

Note: Conjunctions are often used in pairs in a sentence. Identifying one conjunction can thus help in finding another conjunction.
