Noting that the Federal Reserve had raised a key short-term interest rate again last month, analysts said that they expected orders for durable goods to decline soon because rising interest rates makes it more expensive to buy them on credit

A. rising interest rates makes it more expensive to buy them on credit

B. rising interest rates make buying on credit more expensive

C. a rise in interest rates make it more expensive to buy on credit

D. a rise in interest rates make buying on credit more expensive    (B)

E. a rise in interest rates makes it more expensive for them to be bought on credit

求问各位NN，选项中rising interest rates为什么看作是复数呢？说是因为rates和makes主谓一致，这个判断单复数还要揣摩语义是吗？

第一次做的时候竟然水过去了，过两天就要考了，希望各位大神帮忙啊~

嗯？这不明显是raising，动名词做主语吗？用单数啊

raising是修饰rates的，rates才是主语，the raising of interest rates 时raising才是主语
