Noting that the FederalReserve had raised a key short-term interest rate again last month, analystssaid that they expected orders for durable goods to decline soon because risinginterest 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 boughton credit
E里面的them，为什么说，语法上指代orders？

其本上them 會有指代不清的問題，可能是orders ，可能是goods 所以會造成岐義。
正確選項就閃過了them .

a rise in IRs 主詞是 rise , 強調 "上升" , 單數
rising IRs 主詞是 IRs , 強調 rates 本身，複數

还有，a rise in IRs,和rising IR 语法上没有区别？
