10. For many people, household labor remains demanding even if able to afford household appliances their grandparents would find a miracle.
(A) even if able to afford household appliances their grandparents would find a miracle
(C) even if they can afford household appliances their grandparents would have found miraculous
(D) although they could afford household appliances their grandparents would find miraculous
D的would 错误吗？为什么用完成时？这应该是对现在的虚拟，为什么用would have呢？
16. One of Ronald Reagan’s first acts as President was to rescind President Carter’s directive that any chemical banned on medical grounds in the United States be prohibited from sale to other countries.
(A) that any chemical banned on medical grounds in the United States be prohibited from sale to other countries
(C) prohibiting the sale to other countries of any chemical banned on medical grounds in the United States
为什么A错？prohibit from必须加 doing，不能用名词吗？另外词典上关于forbid有sb is forbidden from doing sth的用法．符合GMAT语法吗？
