跪求各位大神解答逻辑类题目

第一题：Most people who shop for groceries no more than three times a month buy prepared frozen dinners regularly. In Hallstown most people shop for groceries no more than three times a month. Therefore, in Hallstown most people buy prepared frozen dinners regularly. 第二题： An author's first novel will become a best-seller only if it has a romantic setting and a suspenseful plot. Since many authors' first novels have neither, it follows that not many first novels become best-seller 这两题我感觉形式上都很相似，但到底哪里存在flaw？ 谢谢大家了！

个人觉得：
第一题的the meaning of “Most people” 前后指的人不一样！
第二题应该是hasty generation！
An author 的example can not support many authors ！

有道理！谢谢了！

第二个我觉得好像不是个体和整体的问题。。an author 好像就是general author。应该是many authors have neither 不能说not many first novels become best-seller。比如你说有许多本书不是好书，你不能说not many=few是好书。many指大于一。似乎不能否定

我hasty generation的意思是：general principle may not prove the especial case！
