提问：
金老師這樣思考是否正確一開始看到Ａ選項我不覺得是三個 ing 的並列我覺得是後面兩個 ving並列，對前面那句話作闡述說明，因為我覺得語意是海洋在人類生存扮演重要角色，而後面是在補充說明怎麼個扮演法，但因為我看到最後一個and前面有逗號所以是三個並列而非兩個,麻煩其他選項也請解釋

提问：
原文的意思moderating 是和mainting 并列关系吗，还是moderating做伴随状语，主语是oceans
c选项为什么错呢，如果是并列关系moderating 前面加by没有问题呐~
如果原文maintaining 和moderating不是并列关系，如果想表示并列关系应该怎么表达呢
