我觉得professor 提了两个问题1）why and 2) which

但student回答得逻辑我不是很懂,这句话well I guess the some movement of capital and labor but are the cause or cost (红的不是很确定，请大家帮助）of factory, problem of worker.是回答which吗?  

I mean the worker don't want to leave their family and friends, ......language, immigrant ristriction....... 是回答why吗？
