19.   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. Therefore, 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

(A) treats a partial solution to the stated problem as though it were a complete solution

(B) fails to distinguish between prevention of a problem and successful containment of the adverse effects that the problem might cause

(C) proposes a solution to the stated problem that does not actually solve the problem but merely makes someone else responsible for solving the problem

(D) claims that a certain action would be a change for the better without explicitly considering what negative consequences the action might have（A）

(E) proposes that a certain action be based on information that would be unavailable at the time proposed for that action

这里A对是不是因为，原文给出的解决办法只能使新产生的遗嘱不发生类似的问题，但是不能解决已有的遗嘱存在的类似的问题，所以说这个问题是“部分的被解决了”？

不知我的理解是否正确，请NN指教。

I agree, how about others?

This practice can creat a problem (1) because the executor will often not know which one of several undated wills is the most recent, and (2) because he/she will not know whether the will drawn up last has ever been found . The solution suggested in the stem is aimed at reason (1). So A is the key.

Cher6068 and mygoalusa, to be honest, if your understanding is right, then B seems to be better than A. Because B reflects your understanding, saying that it does not distinguish between prevention of a problem and containment of the adverse effects of it. (containment: the act of keeping sth under control so that it cannot spread in a harmful way)

In fact, I am not sure about my explanation. Expect criticism.

Hi,everyone above, thank you for your help and interpretation. I got it.

I nearly complete my LSAT exercise and will go back to GMAT CR next monday. I find my weakness from the LSAT exercise and learn much from it. Thank you very much, shyzhang,dphxmg and mygoalusa, you give me so many help. Thank you!
