问题如下：
Which of the following statements is least correct according to the cash flow statement of Company A?
选项：
A.The primary source of cash is operating activities.
B.The primary use of cash is investing activities.
C.The primary use of cash is financing activities.
解释：
B is correct.
The primary use of cash is financing activities, not investing activities.
题目上面给的都是net cash flow，net CFO是正数，net CFF是负数，可是这并不能推断出现金流出主要的use是financing吧。
比如下面这种情况：
CFO中，cash in是5 billion，cash out 是4 billion，所以 net CFO是1 billion；
CFF中，cash in是1 billion，cash out 是3 billion，所以 net CFF是-2 billion；
这种情况跟题目类似，但是也不能说 cash primary use是financing，主要用途依然是operating啊。
而且我记得何老师讲的是，公司现金一定主要跟operating有关
