5. The man's problem is that he cannot have an do the interview with the company's CEO that he wanted for the assignment.
--> Better describe " Planned interview with CEO was canceled"
The man and woman suggest two possible solutions to the problem. The first suggestion is to do research on his own without the interview. The second suggestion is to pick another company and try to arrange a new interview.
I think the second suggestion is better for him. This is because he already found much information about the company that he originally thought about. Most of information is so vague and broad that he cannot write a good paper with it. Also even if he will have to do the interview today, there will be a person who can spare some time for him.
For these reasons, I would recommend the second option for him.
* The male student 가 이미 많은 조사를 마쳤다는 것과,
그 내용이 broad하다? 는 점이 다소 상응하지 않은 내용입니다. 이미 리서치를 끝냈기 때문에
새로 시작하기 어렵다는 반대입장이 더 어울리는 문맥이에요.
또한 학생이 왜 오늘 인터뷰를 마쳐야 하는지 설명이 누락되어 있어요.
