阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
A
Some students from WashingtonAdventistUniversity, near Washington, D.C. have been helping poor children with their schoolwork. But the students did not work with the boys and girls at a traditional school. Every Thursday night, they have been meeting at a laundromat , a place where people go to wash their clothes. At the same time, the students are carrying out a marketing plan they designed for the Laundromat.
The program began with just five children, but has grown to about 20. Before the program works, the business was so bad that the owner had even considered closing his business, which is why the group came in. They were writing a marketing plan to give people a reason to keep coming to the laundromat. Then one student said, “There’re a lot of children hanging around. Why don’t we add teaching?”
The project is part of an international program called Enactus. It was started in the United States 40 years ago. The project is now at more than 1,700 colleges in 36 countries. It wants to give students experience before they graduate, so the project works with the community and with businesses.
Ms. Pichot, the head of the university’s business department, says they invite any business to come in. It’s a free workshop. Her students are working with other businesses in addition to the laundromat. She says the students help business owners increase their profits while gaining experience that they cannot get in school. They volunteer long hours.
Christine Sumampouw is completing her studies this year. She has spent about 1,000 hours as a volunteer. That is more than any other student in the group. She says she has learned a lot from volunteering.

A. They work part-time there.
B. The poor children can’t afford to go to school.[:.]

22.What do we know about Enactus?
A. It is paid to offer help to businesses in need.
B. It aims to help students start their own business.
C. It is created by WashingtonAdventistUniversity.
D. It is a win-win program both for businesses and students.
