26.Down the entrance hall of the school walk four eighth-grade students. Each one is carrying a small basket with a single egg inside. Soon more students join them-each one of them is also carrying a basket with an egg. The eggs in a basket are part of a new school program that helps young people understand that having a baby is a great duty.

At the beginning of the program, the teacher puts the students in

pairs-one girl and one boy. Each pair gets an egg, which they must take care of for two weeks. For those fourteen days, the students have to take care of the eggs as though they were real babies. Students whose eggs get broken have to start the two weeks all over again with a new egg.

One person in each pair must have the egg with him or her at all times-twenty-four hours a day. At no time can they let the egg be out of sight. "If a teacher catches you without your egg," said one student, "she makes you go get it. They are really strict." The teachers also make the students spend half an hour each day sitting with the egg and just watching it. That can get pretty boring. But it's also something that parents spend a lot of time doing.

Children say that the program has helped them understand the duties involved in having a child. "It was really hard," said one student, "You had to think all the time about the egg." (1)、The purpose of the program is to help students grasp the idea of ______.

( B )

A. carrying a basket with an egg

B. bringing up a baby
