[請益] TPO4 - listen , conversation of section 2

[eddyxd (阿魁亞)]

內容是女生抱怨分組的組員都不做事情的那篇@@

question 2是

Why does the professor mention the "free-rider" problem
A. To review a concept he explained in class
B. To give the student a plan to solve her problem
C. To carify the problem the student is facing
D. To explain a benefit of working in groups

解答是B.

但是我覺得是C @@

因為他這邊講這個問題跟幫助他好像無關吧

有人的版本解答是C的嗎@@?

thanks!
