Atestator executed a will, devising his land "to my son and my daughter, share and share alike." shortly thereafter, the daughter died intestate, leaving a child as her only heir. the next year, the testator and his son were involved in a car accident. the testator died immediately. the son died six days later, leaving a will that bequeathed his entire estate to his wife. the jurisdiction has the following statute: "if a devisee, including a devisee of a class gift, who is a grandparent or a lineal descendant of a grandparent of the testator is dead at the time of execution of the will or fails to survive the testator, the issue of such deceased devisee shall take the deceased's share under the will." who owns the land?

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.
