C. if it has worked well in the past中的it指代有问题,it可以指代a course of action,同时也能够指代:incipient trouble ;不要以it不能指代介词中宾语为理由,认为it应该只能指代a course of action; 在C这个句子中committed to a course of action, 这个to是介词,因为TO+N,这个to是做介词用的,所以a course of action就是宾语了,所以既然两个都是宾语,IT指代就有问题了,属于有多个先行词的错误指代情况

到底it能不能指代介词中宾语呢?? Ron说,“it' is ambiguous, because it could potentially refer either to 'course of action' (the intended antecedent) or to 'incipient trouble'. also note that grammatical parallelism doesn't help: both of those possible antecedents are objects of prepositions - neither is the subject of its own clause (which would thereby create parallelism with 'it', which is the subject of its clause). ” 是不是有代词优先指代前面的主语N,再行不通的时候也可以指代介词后面的宾语N?
being 一共有4中情况是对的 1)human being 2) 做名词性成分,这个题就是主语 3)独立主格结构中,n being n。因为普通独立主格不能在名词后面直接加名词,所以为了强行用独立主格表达出这种形式,只能在两个名词中加入being.(只见过一道题) 4) 被动进行时,sth is being done
