麻烦大家帮忙看一下这篇Argument题目

“Because occupancy rates for campus housing fell during the last academic year, so did housing revenues. To solve the problem, campus housing officials should reduce the number of available housing units, thereby increasing the occupancy rates. Also, to keep students from choosing to live off-campus, housing officials should lower the rents, thereby increasing demand.”

错误感觉挺多的，但是好像全是gratuitous assumption？   （好像还有Insufficient sample----这个是万金油）反驳时虽然内容不同但连续三段是同一种错误模式可以吗？能否指点一下还有什么其他方面的错误？

不好意思，麻烦你可以把题号贴一下吗？？

你自己也可以去搜索一下，看以前有没有这题的帖子，可以借鉴一下

Argument 38, 又看了NN的模版后，发现可以在加一个insufficient to draw the conclusion

还有什么别的方面吗？主要是针对七宗罪的
