One study in the United States found that thirty-eight percent of foreign students said they had no close American friends. Elisabeth Gareis teaches in the Department of Communication Studies at Baruch College in New York. She says efforts on how to improve relationships between foreign and American students have yet to be studied in detail. But she says these efforts should begin with the college or university, and that these institutions have been working harder. Ms. Gareis suggests that students should be encouraged to take part in different activities, such as taking walks, going on bike rides, field or camping trips, and attending parties sporting events or film festivals. She says such activities should be held repeatedly throughout the school term to bring students together. She also suggests that foreign students share housing with American students. She says if the new students make friends as they begin school, they will come to feel part of the life and traditions of the university, as well as create long lasting friendships throughout their university career.According to paragraph one, what was the percentage of foreign students had no close American friends?
