Hi Jocelyn,
The reason James's explanation employs conditional reasoning in the prephrase process is because coming up with a general conditional connection between the premises and conclusion of an argument is a great way to strengthen that argument. That conditional connection might, in some cases,
incorporate a causal idea, as it does here.
Consider a hypothetical argument. "Because a predictable study schedule leads to testing success, therefore I should adopt such a schedule in my LSAT studying." A general rule that strengthens that argument might create a conditional connection between the premise and the conclusion by saying, "If a study technique leads to testing success, then it should be adopted." Notice how both the premise of the argument and the sufficient condition of the principle incorporate that
causal idea of a study strategy causing (leading to) test success?
The same thing is happening here. The conditional principle that James prephrased is great, and fits answer choice A very well. This is something we see
extremely often on Strengthen-Principle questions. The answer states a general conditional rule that can be used to connect the stimulus's premise to its conclusion. The form of that conditional is ordinarily [Premise}
[Conclusion].
Within the conditional principle here, though, there is a cause and effect relationship, which is also present in the argument in the stimulus. The argument in the stimulus assumes that what is
causing the Johnson campaign to quote the opponent out of context is that the Johnson campaign thinks the out-of-context quotation is the
most politically damaging form of the quote. In other words, assuming the campaign would be motivated (i.e. caused) to do the most damaging thing possible, the fact that the campaign doesn't ever quote the opponent
in context means they think it wouldn't be as politically damaging to quote her in context. Answer choice A incorporates that cause/effect assumption. What will cause a campaign to act in a certain way, according to answer choice A? What will cause them to act that way is whatever they believe to be the most damaging to their opponent politically.
I hope this helps clarify!
