TPO V03的聽力第二篇的重聽題 - 英檢

重聽題題目是這樣的：

6. Listen again to part of the lecture. Then answer the question.
What does the professor imply when she says this:

A There is disagreement about the idea she has presented.
B She does not plan to discuss all the details.
C Her next point may seem to contradict what she has just said.
D The point she will make next should be obvious to the students.


再聽一次的內容為：

So, hummingbirds have to rely on plants in natural habitat. And, it goes
without saying, but, well, the opposite is true as well. Plants depend on
hummingbirds, too.

他問說，講者為何要說it goes without saying

我原本填的答案為B

但答案為D


拜託有高手或者知道為什麼答案是D的人幫忙解答

聽了好多次一直覺得好困惑
