Kaplan's Explanation -
Identify the Question Type: The word "weaken" signals that this is a Weaken question.
Predict a Weakener that disproves the central assumption.
Untangle the Stimulus: The conclusion of the argument is that the ancient script will never get deciphered.
The author’s evidence is the conjecture that, because universities want the prestige of being first to crack the script, they won't share their progress, which will prevent the scholars from building on each other’s work.
Predict the Answer: The author is suggesting that the lack of cooperation is going to prevent the script from being deciphered. That assumes that university researchers cannot succeed unless they build upon each other’s work.
A good weakener would show that the researchers can succeed without building on each other’s work.
Evaluate the Choices:
(B) is correct. It suggests that the researchers can succeed when working alone, thus weakening the author's assumption that people need to build upon each other's work to succeed. (A) is much broader than the terms of the argument. This suggests that the competition will provide momentum for university research, but does not directly counter the author's assertion that the script will not be deciphered.
(C) would not weaken the argument. Extra funding does not guarantee success, so the author's argument still stands.
(D) would not weaken the argument. Even if there were open forums within universities, the author could still claim that universities need to work together and share ideas with each other. If they don't, then the author can still claim that the script will not be deciphered.
(E) would not weaken the argument. What works for the military does not necessarily work for universities. Moreover, there's no indication that individual military groups are working independently.
Thus, this would not provide a relevant enough comparison to affect the author's argument.
TAKEAWAY: To weaken an argument that presupposes that something is necessary for success, look for an answer that shows why it's not needed.
