【学生态度】女生赞成
【同意原因】(1)她自己也是resident advisor, 可以把她的经验介绍给新的advisor, 有助于解决roommate之间的conflict;(2)因为开学会有很多学生move in, housing staff会很忙，这样可以腾出更多的时间和精力来分配住宿。来源：北京新航道
Task 4
【讲座主题】task partitioning
【内容讲解】通过分工来增加效率
【1个例子】教授举了leaf-cutter ants的例子，说它们一般分成三组：第一组爬到树上cut leaves;第二组把落在地上的叶子cut into pieces, easily carried;第三组把cut好的树叶运回nest。最后教授说这样的分工效率很高，因为它们都work independently, 还说到这样不用都去爬树，不会tiring out too soon。
Task 5
【一个问题】男生约了Tina在bookstore门口还她笔记，因为明天要考试了，他之前借来看的，现在要还给她。但是等了15分钟Tina还没有来，打电话也没接，男生马上要去做part time job了
【解决方案】另外一个女生给了他两个建议：(1)送去Tina的宿舍，但男生说这样他的part time job就要迟到了;(2)可以通过campus mail, 然后给Tina的手机留言，但是男生说不知道mail好不好用，怕Tina下午才能收到笔记，来不及复习。
