Exposure to certain chemicals commonly used in elementary schools as cleaners or pesticides causes allergic reactions in some children. Elementary school nurses in Renston report that the proportion of schoolchildren sent to them for treatment of allergic reactions to those chemicals has increased significantly over the past ten years. Therefore, either Renston’s schoolchildren have been exposed to greater quantities of the chemicals, or they are more sensitive to them than schoolchildren were ten years ago. Which of the following is an assumption on which the argument depends? A.The number of school nurses employed by Renston’s elementary schools has not decreased over the past ten years. B.Children who are allergic to the chemicals are no more likely than other children to have allergies to other substances. C.Children who have allergic reactions to the chemicals are not more likely to be sent to a school nurse now than they were ten years ago. D.The chemicals are not commonly used as cleaners or pesticides in houses and apartment buildings in Renston. E.Children attending elementary school do not make up a larger proportion of Renston’s population now than they did ten years ago. 答案是c 請問一下答案c取非有反駁結論嗎我覺得取非反而支持阿謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 71.100.137.109
