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.

3F：→ pentimento:成为「另有他因」的反驳。而加回 not 之後，成为 09/23 08:57
4F：→ pentimento:「他因」反驳的反驳，所以是成为假设或支持。 09/23 08:58
