Assumption: 106 106. 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 Renstons 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 Renstons elementary schools has not decrease d 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 Renstons population now than they did ten years ago. Evaluate the Argument: 114, 124 114. Normally, the pineal gland governs a persons sleep-wake cycle by secreting melatonin in response to the daily cycle of light and darkness as detected by the eye. Nonetheless, many people who are totally blind due to lesions in the visual cortex of the brain easily maintain a 24-hour sleep-wake cycle. So the neural pathway by which the pineal gland receives information from the eye probably does not pass through the visual cortex. For purposes of evaluating the argument it would be most useful to establish which of the following? (A) Whether melatonin supplements help people who have di
