with lots of difficult problems

with lots of difficult problems ______,the newly-elected president is having a hard time.
A.settled B.settling C.to settle D.being settled

选c
to settle
绝对正确,
再问： 书上答案是settled。。。为什么 它说 本题考查with的复合结构，problems与settle之间是被动关系，故用“with+宾语+过去分词”
再答： 动词不定式to settle做定语表示现在或将来要解决的难题；过去分词settled作定语表示已经解决的难题；现在分词的被动式being settled作定语表示正在被解决的难题。所提供的语境the newly-elected president is having a hard time说明新任总统现在和将来都有难以解决的问题，所以要用to settle作定语 要知道，书上经常会遇到与其他地方不一样的冲突，（我那个书也一样） 我找了好几个地方都是to settle 所以书上肯定错了，至于为神马，呃，问书的编者去
