What is the passage mainly concerned with?
A sample of a population is often examined for the following purposes except ______.
选项
A、to make a more accurate prediction of trend
B、to improve efficiency and avoid unnecessary work
C、to save the trouble of approaching every member
D、to predict characteristics of the entire population
答案
A
解析
细节理解题。找到文章中关于人口抽样的内容,再进行比较选择。但要注意选的是除外的那一项。文章最后一段讲到抽样100个小孩来进行分析预测,A“进行更加准确的趋势预测”,抽样本身就不可能是为了更加“准确”,所以A错,应该选A。B“提高效率,避免不必要工作”,这正是抽样的作用;C“省去找每个成员的麻烦”,这也正是人口抽样的优势;D“预测全体人群的特征”,正是人口抽样的目的,所以选A。
