GWD 3-24急问

Q24:

If ab = 1, what is the value of (axb)(ayb)?

(1)   ax = by = 2

(2) 2xy = 4

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

两个条件都可以算出，但得到的结果不同，到底该怎么选？

之前的讨论没有定论，马上就考了，急问!!!

最近模考GWD数学狂错，VERBAL错三四个的样子但前十道必错两道，郁闷郁闷郁闷！！！

其实2楼那个链接里面写得也比较清楚了

GWD的题目也不能保证是完全正确的~我个人认为ETS还是不会出互相矛盾的选项的~

如果正在实战中遇到，我还是选D
