180.
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



正确选B
A为什么不对为什么不能把rising……看成是主语，这样谓语动词就可以使单数了啊~

you have to tell the deference between "rise" and "raise" first, then you probably know that "rising" used as participle is just a modifier for "rates"; further more, the pronoun "them" makes confusion, which should be eliminated.

Above is just my guess in this particular case, you may wait for some DN' explanations. Thanks

我觉得interest rates是主语 ，而rising（adj）是修饰该主语的定语。所以应该是make而不是makes
