We're looking for the answer choice that highlights what Emile and Sabina disagree about.
In looking at the stimulus, we know that Sabina and Emile agree that words do not affect the soundness of an argument. Sabina believes that this means that words do not affect whether or not an argument is good or not. However, Emile believes that words do matter and have the ability to make an argument poor even if it is sound.
In looking at the answer choices, we need to find one that matches this difference of opinion.
(E) says, "a factor that affects neither the truth of an argument’s premises nor the logical relation between its premises and its conclusion can cause an argument to be a bad one"
(E) captures the point at issue really well. Sabina and Emile both do agree that words do not affect the soundness of an argument. However, what they disagree about is whether or not words have the ability to make an argument bad. This is the point at issue, and this is why (E) is the correct answer.
Does this make sense? Let us know if you have any more questions!
