Passage:

Each child has his individual pattern of social, as well as physical development. Some of it dependson his home life and his relationships with the, people who love him. Children in large familieslearn how to get along with others through normal brother-sister- play and tussles. An only child,on the other hand, may have to learn his lessons in social living through hard experiences on theplayground or in the Class room. Twins who always have one another to learn on may be slow inresponding to others because they do not need anyone else.

A child who is constantly scolded and made to feet he does everything wrong may love a difficulttime developing specially. He may be so afraid of displeasing the adults around him that he keepsto himself (whether he can’t get into trouble), or he may take the opposite route and go out of hisway to create trouble like the isolated child, he too may return to infantile pleasures, developinghabits that will safety him. But create barriers towards social contact.

1. The main idea in this passage is that

(a) Twins are slower in developing than single children

(b) Only children take longer to develop

(c) Children develop socially, physically and developmentally according toan individual pattern;

(d) Secure children take longer to develop.
