Astronomer: I have asserted that our solar system does not contain enough meteoroids and other cosmic debris to have caused the extensive cratering on the far side of the moon. My opponents have repeatedly failed to demonstrate the falsity of this thesis. Their evidence is simply inconclusive; thus they should admit that my thesis is correct.

A
criticizes the astronomer’s opponents rather than their arguments
The author does not attack the character, background, or behavior of the opponents. The premise merely points out that the opponents have not proven the thesis false.
B
infers the truth of the astronomer’s thesis from the mere claim that it has not been proven false
The author infers the truth of the thesis from the claim that the opponents haven’t proven the thesis false. This is a flaw because the thesis can still be false even if no one has proven it false.
C
ignores the possibility that alternative explanations may exist for the cratering
The author’s thesis is that meteors and other cosmic debris from our solar system did not cause the cratering on the moon. The author is open to other explanations; he didn’t conclude that there is one particular explanation for the craters.
D
presumes that the astronomer’s thesis should not be subject to rational discussion and criticism
The author does not assume that the thesis shouldn’t be subject to criticism. The author never asserts that the opponents should not have tried to criticize the thesis.
E
fails to precisely define the key word “meteoroids”
Failure to define a word is not a flaw. Words can simply take on their ordinary dictionary definitions. Here, “meteoroids” means something like space rocks.
