做过prep补充新题的童鞋请进，求解题思路！

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

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

正确答案是B，我选的E。

不明白为什么要用分词rising，从句中不是说上个月已经raised了吗？还是说rising 表达了其他的含义？

对划线部分的理解是，利率增长以后让赊账购买变得更贵。不知道是不是这个意思？

总之觉得**的增长，用a rise in **,an increase in **更贴切些。

请大家点拨！谢谢谢谢！

对了，对了，这个忘记了~~~同一句中相同代词指代一致~~~~还是要高人指点，绕半天了~~~

呵呵！谢谢edmundshi，还有一道题，请点拨！

Despite recent increases in sales and cash flow that have propelled automobile companies' common stocks to new highs, several industry analysts expect automakers, in order to conserve cash, to set dividends more conservatively than they were
                            

A. to set dividends more conservatively than they were

B. to set dividends more conservatively than they have been

C. to be more conservative than they have been in setting dividends

D. that they will be more conservative than they were in setting dividends

E. that they will be more conservative than they have been to set dividends

正确答案选C。我选B。

B选项错在哪里？是不是B选项比较的是set 这个动作，than后面应该用they have（set)，而不是they have been?

E选项比较对象都对等：automakes be more conservative than they have been.

请大家指点！谢谢了 !
