问题     What do a 15-year-old high school sophomore named Tanja Vogt and Thomas Paine have in common? The answer is that both inspired major changes in their societies by writing an essay.
    In October 1988, Vogt--a student at West Milford High School in New Jersey--read an article in her local newspaper that disturbed her. The article reported that the Board of Education had decided to use polystyrene (聚苯乙烯) trays in the lunchroom because they were less expensive than paper.
    Vogt knew from her science class that polystyrene can have harmful effects on the environment. In the first place, it is not biodegradable, meaning that it can’ t be broken down by natural biological processes. In addition, some polystyrene products release gases called chlorofluo rocarbons (CFCs氟氯化碳) into the air. Scientific evidence indicates that these CFCs break down the protective ozone layer (臭氧层) of the atmosphere.
    Vogt decided to write a paper for her social studies class on the issue of polystyrene. Her teacher, Carl Stehle, read her paper to the class. After reminding students that Thomas Paine had had to persuade many hesitant colonists to support the American Revolution, Stehle challenged his class to do something about the polystyrene problem.
    Vogt and her classmates immediately conducted a survey in the high school and middle school. They discovered that a large majority of students said they wanted to switch back to paper goods in the cafeteria. When they presented their findings to the Board of Education, the board’ s business administrator did a survey of his own. He found that roughly 80 percent of the students in the two schools would be willing to pay an extra nickel to eat their lunch from paper trays. As a result, the board voted in December to change to paper trays in all the township’ s schools as of February 1, 1989.
It can be inferred from the passage that ______.
选项 A、there were altogether only two schools--the high school and the middle school in the small town where this story took place
B、polystyrene is the major factor that has done harm to the protective ozone layer of the atmosphere around the earth
C、the Board of Education actually had known the harmful effects of polystyrene on the environment before making the decision
D、Vogt and her classmates at last managed to persuade the Board of Education into changing their decision wish their academic knowledge
答案C
解析 推断题。分别对四个选项进行定位分析。根据最后一段中“When they presented their findings to the Board of Education，the board’s business administrator did a survey of his own．．．willing to pay an extra．．．trays．”可知，the Board of Education做出这个决定的主要立足点是因为纸质托盘较贵，而当Vogt等人向其提交调查结果时，the Board of Education并没有就聚苯乙烯对环境有害展开调查，而只是在学生中作了一个关于愿意不愿意使用较贵的纸质托盘的调查，由此可推断其事先是知道聚苯乙烯对环境的危害性的。选项D错在with their academic knowledge，因为最终使the Board of Education改变主意的并不是Vogt等人的学术知识，而是其对民意的调查(survey)。故答案为C。
