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?

The number of school nurses employed by Renston's elementary schools has notdecreased over the Past ten Years. Children who are allergic to the chemicals are no more likely than other children to have allergies to other substances. 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. The chemicals are not commonly used as cleaners or pesticides in houses and apartment buildings in Renston. Children attending elementary school do not make up a larger proportion of Renston's population now than they did ten years ago.

题干翻译
在Renston，一些儿童对某些化学物质有过敏反应。小学护士报告称，在过去十年里，因这些化学物质过敏反应被送去治疗的学童比例显著增加。因此，要么是Renston的学童接触到了更多数量的这些化学物质，要么是他们比十年前的学童对这些化学物质更敏感。 逻辑链
过敏比例增加→接触量多或更敏感 问题类型
假设（assumption）。 推理过程
论点认为学童过敏比例增加的原因是接触化学物量增多或者更敏感。要使这个论点成立，需要排除其他可能导致过敏比例看似增加的原因。如果现在有过敏反应的孩子比十年前更有可能被送去看校医，那就可能是送医倾向的变化导致统计的过敏比例增加，而不是真的接触量或敏感度的问题，所以需要假设现在孩子被送医的可能性没有比十年前高。 选项分析
A选项：Renston小学雇佣的校医数量在过去十年没有减少。校医数量与过敏比例增加的原因无关，排除。 B选项：对这些化学物质过敏的孩子不比其他孩子更易对其他物质过敏。讨论的是对其他物质过敏情况，与本题化学物质过敏比例增加原因无关，排除。 C选项：对这些化学物质有过敏反应的孩子现在不比十年前更有可能被送去看校医。符合上述推理，是论点成立的必要假设，当选。 D选项：这些化学物质在Renston的房屋和公寓中不常被用作清洁剂或杀虫剂。化学物质的用途与学童过敏比例增加原因无关，排除。 E选项：现在上小学的孩子在Renston人口中所占比例不比十年前大。学童在人口中的比例与过敏比例增加原因无关，排除。
