(单选题)

What does the author want to stress by listing the sharp differences?

A.Too many fathers leave STEM.

B.It’s hard for mothers to make a balance.

C.STEM jobs are no longer popular.

D.It’s impossible to have a successful career.

参考答案：B

参考解析：

推理判断题。根据最后一段的最后一句“These sharp differences make clear that，even though the reduction rate for fathers is higher than expected, mothers still face particular career challenges.”（这些明显的差异表明，即使父亲的复位率高于预期，母亲仍然面临特定职业的挑战。）可知，作者想通过列举这些明显的差异来强调母亲们很难做到平衡。故选B。
