longman听力一段对话中有个语气和词组不太清楚，请指教

（woman) This is an interesting assignment we have for psychology class.

(man)       Interesting?It's going to be a lot of work.

(woman)   What's so hard about it? We just have to make up  a survey questionnaire related to theories from the class.

(man)      Making up a survey questionnaire isn't so hard. But we have to find 50 people to fill out the questionnaire and then write up a report analyzing the data.

(woman) It'll be easy to find 50 people to fill out the questionnaire. We can do that in one afternoon at the student center. That actually sounds like fun to me.

(man)     That'good. I don't mind preparing the questionnaire and analyzing the data, but getting 50 people to answer the questionnaire does not seem like fun to me.

What's so hard about it?

是什么意思,是这有什么难的,是这个女的对这个男的说的反问语气，还是这个女的询问这个男的，这件作业里什么东东你觉得困难呢,只是一般的问句呢？

对这个语气不太清楚

另外，make up a survey questionnarie在这里是学生自已设计调查问卷　，还是老师发下来调杳问卷，学生把空白处填上的意思呢．

请指教．谢谢．
