71. In order to improve thelong-term savings rate of its citizens, Levaska’s government has decidedto introduce special savings accounts. Citizens can save up to $3,000 a year in special accounts without havingto pay tax on the interest, unless they withdraw money from the account beforethey reach the age of sixty-five.  Ifthey do withdraw any money before that age, they have to pay tax on theaccumulated interest and a penalty.

75. Kernland’s government restricts the export ofunprocessed cashew nuts in order to ensure a low-cost supply for domesticprocessing plants.  Though the policyconstrains farm income and limits the number of farmers who can profitably growcashews, the government defends it on the grounds that, since the processingplants are in urban areas, removing the restrictions would hurt efforts toreduce urban unemployment.  However, thepolicy may actually have contributed to urban unemployment, since __________.

71的逻辑分类为因果分类，排除方案推理，因为原文对方案进行了评价：in order to improve the long-term savings rate
那么，是不是说，方案的目的也算作评价？

另外，75题，方案为政府限制unprocessed cashew nuts的出口, 取消这一限制会导致失业率上升，保留这一限制也可能导致失业率上升。
那么，是不是因为，原文一边说方案可能导致失业率上升，一边又说方案可能不会导致失业率上升，态度模糊，因此原文不算对方案进行了评价，故把75题归为方案推理这一大类？
