Mr Hand has much experience dealing with teenagers. He always has good solutions___their problems

B

用法和the answer to the question类似再仔细点介词的用法是没有道理可讲的，我只能用类比了 the way to streetthe key to the door 虽然都和of一个意思，但是就是不能用of, 你这个题目就是问题的答案，不就和the answer to the question类比吗我是说原题上面为什么选tosolutions___their problems的意思是问题的解答 正好和the answer to the question产生类比
