GWD-9-Q3:

Because of wireless service costs plummeting in the last year, and as mobile phones are

increasingly common, many people now using their mobile phones to make calls across a

wide region at night and on weekends, when numerous wireless companies provide

unlimited airtime for a relatively small monthly fee.

 

A. Because of wireless service costs plummeting in the last year, and as mobile phones are increasingly common, many people

B. As the cost of wireless service plummeted in the last year and as mobile phones became increasingly common, many people

C. In the last year, with the cost of wireless service plummeting, and mobile phones have become increasingly common, there are many people

D. With the cost of wireless service plummeting in the last year and mobile phones becoming increasingly common, many people are

E. While the cost of wireless service has plummeted in the last year and mobile phones are increasingly common, many people are

我选的是D，但给的答案是E。E是错的吧？IMO，其中的has plummeted in the last year 的时态不对？还有因用了while,原句的因果关系也变了
