题目中的assumption是针对free time的:since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer.
但是survey是针对time(没有区分free还是work time)做的:in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computer report no change in time spent watching television.
所以出现逻辑错误: 混淆概念
E选项能得出free time的数据,从而评价survey是不是证明了assumption的对或错.
