A certain computer program creates temporary files on the computer on which it is installed. The files contain a programming error, or "bug", that, in rare cases, may cause the computer to freeze up. The temporary files are purged 90 days after the program is installed. Since no program will copy the bug to any other file, any computer containing the program that freezes more than 90 days after the program has been installed does not freeze because of this program.
Which of the following, if true, most seriously weakens the conclusion above?
(A) A computer that freezes due to the installation of the program in question produces a display that is similar to that which is displayed when computers freeze for many other reasons.
(B) The code that causes the freezing will be eliminated in a future release of the program.
(C) Other bugs in the programming may reveal themselves more than 90 days after the program is installed.
(D) A person can copy the programming code containing the bug to other files that are purged with less frequency than the temporary files.
(E) There are some computers on which the program is installed that appear to be unaffected by the programming bug.

Dear
avohden,
I'm happy to help.
This Kaplan question is a re-written version of OG12, CR #30, about red blood cells and malaria. The question in the
OG is, not surprisingly, a very well-written question. In my opinion, Kaplan did not do a good job in the process of rewriting. In
OG question,
(D) is clearly correct, and
(C) is unambiguously wrong. In the Kaplan question, it's not as clear. Yes, we can probably say that
(D) is the strongest answer, the one that "
most seriously weakens the conclusion," but a strong argument can be made for
(C), and the grounds for eliminating it are less cogent. Do the other bugs in the programming lead to problems that eventually cause the computer to freeze? Maybe, maybe not. It's unclear, but programming bugs are certainly not promising. The uncertainty about whether this would be relevant is presumably what disqualifies
(C) as the answer. What's bizarre about
(D) --- if a person is copying programming code, wouldn't they be aware of this and the risks it might entail? I work on my computer all day, and I NEVER open up the code of anything and copy code from one place to another. I believe what they are trying to suggest that, by saving files or re-opening a certain program or something ordinary such as these, the user inadvertently copies the code and, with it, the bugs. I think that's what they are trying to suggest, but they don't say it particularly clearly.
The
OG question I would give a grade of A, as I would give virtually every question in the
OG. The Kaplan question here, I would give a C or C-. This does not have the same logically tight quality that the
OG questions have.
Here's another well-written CR question, for further practice:
