Watch the two videos carefully. Each one is usually about 1 hour. It talked about topics 6-8. You can choose two of the three to write. I have put the requirements of this article in the following document. Because my work requires 5 topics, I have already written three, you only need to write two. Please try to imitate the three that I have finished. No need to modify what I have already done. This work does not need to be cited, and works cited is not required to be added. All content needs to come from the video.
