【答案解析】{{B}}Use of Science Club Membership Dues{{/B}} The Science Club membership dues were used in a variety of ways. There were six areas of expense that had to be covered by the money from members dues. One half of the membership dues, namely, 50% , went for scholarship assistance to needy members. A quarter of the dues, i. e. 25% , was spent on producing the club's magazine. Members of the club devoted the third largest amount, 16%, to prizes for outstanding work in science. The annual Science Club trip to museums and scientific institutions required 7% of the income from dues. The smallest amounts, 1% each, were used for office supplies and correspondence, including letters, telegrams, and long-distance telephone calls.
