美国学术能力评估考试（SAT）
单选题In context, which word or phrase is best inserted at the beginning of sentence 4 to connect it with the rest of the paragraph?A To breed them,B Although,C And,D To protect them,E Additionally,
题目
To breed them,
Although,
And,
To protect them,
Additionally,
参考答案和解析
一个句子不能用“and”开始，所以C项可排除。因为这个句子与之前表述的思想既不形成对比也不是前面句子的进一步阐释，所以B和E项错误。因为之前的句子讨论的是龙虾的保护，而不是“breeding”，所以A项错误。只有D项合适。
