Exposure to certain chemicals commonly used in elementary school as cleanser or pesticides causes allergic reactions in some children. Elementary school nurses in Renston report that the proportion of school children sent to them for treatment of allergic reactions to those chemicals has increased significantly over the past 10 yrs. Therefore, either Renston's school children have been exposed to greater quantities of the chemicals, or they are more sensitive to them than school children were ten yrs ago.
Which of the follow. is an assumption on which the argument depends?
A) The no. of school nurses employed by Renston's elementary school has not decreased over the past 10 yrs.
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 10 yrs ago
D) The chemicals are not commonly used as cleanser or pesticides in houses and appt. buildings in Renston.
E) Children attending elementary school do not make up a larger proportion of Renston's population now than they did 10 yrs ago.
