题目解析:
选项 A:“determine what issues came before the assembly”(决定哪些议题提交给公民大会)。原文中 “prepared the agenda for the meetings of the assembly”(为公民大会的会议准备议程),“准备议程” 其实就是确定哪些议题能被讨论,和 A 选项的 “determine what issues came before the assembly” 意思一致,所以 A 正确。
选项 B:“prepare the agenda for the courts”(为法庭准备议程)。但原文明确说 “courts, which took care of most judicial matters”(法庭负责司法事务),准备议程的是 council 为 assembly,不是为 courts,所以 B 错误。
选项 C:“carry out the assembly’s policies”(执行公民大会的政策)。原文说 “Various committees acted as an executive branch, implementing policies of the assembly...”(各种委员会作为行政分支,执行公民大会的政策),执行政策的是 committees,不是 council,所以 C 错误。
选项 D:“oversee the distribution of food and water”(监督食物和水的分配)。原文同样是 “committees...supervising, for instance, the food and water supplies...”(委员会监督食物和水供应),不是 council 的作用,所以 D 错误。
