Which of the following is the second sentence of the passage?

The correct order of sentences is c, b, f, e, a and d Here, a cannot be the first sentence, since the problem needs to be discussed first. a is a solution to the problem. So, the first sentence of the passage is c . b follows c. f also follows c , but it is perfect to use f after b. After f is e , as it also mentions another problem faced by children. a follows e because, in d, the word ‘also’ is mentioned, which states that a solution has already been said and in addition to that, this also is recommended. So, after a, d follows.
