When a new restaurant, Martin's Cafe, opened in Riverville last year, many people predicted that business at the Wildflower Inn, Riverville's only other restaurant, would suffer from the competition. Surprisingly, however, in the year since Martin's Cafe opened, the average number of meals per night served at the Wildflower Inn has increased significantly.
Which of the following, if true, most helps to explain the increase? 想问一下 这个问题是属于什么类型的问题呢？？是加强吗？？还是假设？？
问题二：逻辑中 假设题型会有新元素引入吗？？
问题三：Maize contains the vitamin niacin, but not in a form the body can absorb. Pellagra is a disease that results from niacin deficiency. When maize was introduced into southern Europe from the Americas in the eighteenth century, it quickly became a dietary staple, and many Europeans who came to subsist primarily on maize developed pellagra. Pellagra was virtually unknown at that time in the Americas, however, even among people who subsisted primarily on maize. 这道题目中 哪个是前提？哪个是结论呢？？
请nn帮忙解答一下吧？？马上就要考试了 逻辑还不太好 多谢指点~~· |
