“[The Native Americans] are so ingenuous and free with all they have, that no one would believe it who has not seen it; of anything they possess, if it be asked of them, they never say no; on the contrary, they invite you to share it and show as much love as if their hearts went with it, and they are content with whatever trifle be given them, whether it be a thing of value or of petty worth. I forbade that they be given things so worthless as bits of broken crockery and of green glass and lace-points, although when they could get them, they thought they had the best jewel in the world.”

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.
