Read the passage, then choose the correct answer

Many people now think that teachers give students too much homework. They say that it is unnecessary for children to work at home in their free time.

Moreover, they argue that most teachers do not properly plan the homework tasks they give to students. The result is that students have to repeat tasks which they have already done at school.

Most people agree that homework is unfair. A student who can do his homework in a quiet and comfortable room is in a much better position than a student who does his homework in a small, noisy room with the television on. Some parents help their children with their homework. Other parents take no interest at all in their children’s homework.

It is important, however, that teachers talk to parents about homework. A teacher should suggest suitable tasks for parents to do with their children. Parents are often better at teaching their own children!
