P: People report increasing time in Computer report no change in viewing TV.

A. the numbers错误, twice后面要跟单数的number,即twice the number;但是改为the number后,指代特定的数字还是用that number更为明确
B. Correct; that number指代前面总和的469000,如果是the number,没有指代对象,似乎说是the number of trucks
如果是三个形容词的并列,应该是E不加and
所以不能是三个形容词的并列,只能是前面两个形容词用and连接
后面的that pay 与that are XX 并列表示industries的情况
