Gia is writing an essay with the following claim: The school should require all students to wear uniforms. A. Opponents of the uniform policy may argue that uniforms are too expensive, but studies have shown that uniform requirements almost always save families money in the long run.
B. School uniforms will have a positive impact on our school because students will be valued for their personalities and not their expensive brand-name clothing.
C. Those who are against school uniforms will probably argue that uniforms will stifle student individuality and deprive students of a much-needed outlet for self-expression.
D. Although uniforms are not always fashionable, students who wear them are likely to find that their morning routines run more smoothly and include less stress.

It is widely assumed that people need to engage in intellectual activities such as solving crossword puzzles or mathematics problems in order to maintain mental sharpness as they age. in fact, however, simply talking to other people—that is, participating in social interaction, which engages many mental and perceptual skills—suffices. evidence to this effect comes from a study showing that the more social contact people report, the better their mental skills. which of the following, if true, most seriously weakens the force of the evidence cited? (a) as people grow older, they are often advised to keep exercising their physical and mental capacities in order to maintain or improve them. (b) many medical conditions and treatments that adversely affect a person's mental sharpness also tend to increase that person's social isolation. (c) many people are proficient both in social interactions and in solving mathematical problems. (d) the study did not itself collect data but analyzed data bearing on the issue from prior studies. (e) the tasks evaluating mental sharpness for which data were compiled by the study were more akin to mathematics problems than to conversation.
