Many people change their wills on their own every few years, in response to significant changes in their personal or financial circumstances. This practice can create a problem for the executor when these people are careless and do not date their wills: the executor will then often know neither which one of several undated wills is the most recent, nor whether the will drawn up last has ever been found. Ttherefore, people should not only date their wills but also state in any new will which will it supersedes, for then there would not be a problem to begin with. The reasoning in the argument is flawed because the argument ['fails to distinguish between prevention of a problem and successful containment of the adverse effects that the problem might cause', 'treats a partial solution to the stated problem as though it were a complete solution', 'proposes a solution to the stated problem that does not actually solve the problem but merely makes someone else responsible for solving the problem', 'claims that a certain action would be a change for the better without explicitly considering what negative consequences the action might have']
