- From the end of the problem as well
Recently, there have been frequent safety incidents. An explosion in a university laboratory took the lives of three students. I really express my deep condolences. So I really feel very scared, so I would like to ask, I am a polymer major, which direction will be relatively safer to choose when I am further studying? |
