A random sample of shoppers responded to the questions contained in a marketing survey. Six months later, another random sample of shoppers responded to exactly the same questions, except that the questions were now arranged in a different order. The pattern of responses to many individual questions was greatly different, thus demonstrating that a question will sometimes elicit different responses depending only on what question precedes it. The argument above depends on which of the following assumptions

A. The reordering of the questions did not put each question in a different sequential position from its position six months previously.
B. Shoppers who respond to a marketing survey do not generally remember six months later what responses they gave.
C. There was no motive for the second survey except that of discovering whether the ordering of the questions mattered.
D. The survey was not composed of questions to which shoppers would give different responses at different times of the year.
E. The first sample of shoppers did not have any individuals in common with the survey sample of six months later.

Although computers can enhance people’s ability to communicate, computer games are a cause of underdeveloped communication skills in children. After-school hours spent playing computer games are hours not spent talking with people. Therefore, children who spend all their spare time playing these games have less experience in interpersonal communication than other children have. The argument depends on which of the following assumptions

A. Passive activities such as watching television and listening to music do not hinder the development of communication skills in children.
B. Most children have other opportunities, in addition to after-school hours, in which they can choose whether to play computer games or to interact with other people.
Children who do not spend all of their after-school hours playing computer games spend at least some of that time talking with other people.
D. Formal instruction contributes little or nothing to children’s acquisition of communication skills.
E. The mental skills developed through playing computer games do not contribute significantly to children’s intellectual development.
