标题: 求问OG13小蓝本里的27题！！

Obtaining an investment-grade rating will keep the county's future borrowing costs low, protect its already-tattered image, and increase its ability to buy bond insurance.

(A) Obtaining an investment-grade rating will keep the county's future borrowing costs low, protect

(B) To obtain an investment-grade rating will keep the county's future borrowing costs low, and protect

(D) To obtain an investment-grade rating would keep the county's future borrowing costs low, protecting

(E) Obtaining an investment-grade rating, keeping the county's borrowing costs low, would be protecting

这题根据平行选出A容易，但是有两处怎么都想不明白
1.不定式做主语和现在分词做主语有什么区别？
2. 为什么OG说：因为E选项中的keeping the country's borrowing costs low修饰了前面句子的主语就导致了increase缺少了主语呢？？
求大神解答！！！

不定式：强调具体的、一次性的动作
现在分词：强调多次的、抽象的动作

e中 be protecting 和increase 不对称
