(1) In the first box, the number of bulbs that are not broken is 15 times the number of broken bulbs.
(2) The total number of bulbs in the first box is 9 more than the total number of bulbs in the second box.

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.

这道题为何不是D？
(2) The total number of bulbs in the first box is 9 more than the total number of bulbs in the second box.
第一个盒子的灯泡总数 是 9 + 第二个盒子的灯泡数，这明显可以求的呀？
