In a physical education class, 20 students were tested on archery target shooting. These students were then given a two-day training course in archery technique. The students were tested again and showed a 30 percent increase in accuracy. This result proves that the course was effective in increasing people’s target-shooting accuracy. Which of the following, if true, gives the strongest support to the argument above?
选项
A、The students were all excellent athletes, and excellent athletes tend to be good at target shooting.
B、The first testing session functioned as a practice session for the second testing session.
C、The accuracy with which people can shoot arrows is strongly related to the sharpness of their vision.
D、A similar group of students who were also tested on archery target shooting but were not given the course did not show an increase in accuracy.
E、Excellence in archery target shooting is an accomplishment achieved by relatively few of the people who take up the sport.
答案
D
解析
本题也是由一个试验“上了两天的培训课准确率提高了30%”,而得出一个解释性结论“培训课有效”,属于典型的“B,A”题型。(D)通过指出没有培训(
),就没有准确度的提高(
),即
→
,所以(D)是一个“无因就无果”(即A可行或A有意义)的假设,而假设可作为一个很好的支持。所以(D)是正确答案。
