Sure thing.
It's a Strengthen question. The argument core is as follows:
CONC
The results of democratic elections can't be viewed as representing the unadulterated preferences of the people
(translation: voters in democratic countries have been brainwashed to some extent in terms of whom they end up voting for)
why?
PREM
In democratic countries, there are political strategists who are paid to manipulate public opinion, just as advertisers are paid to instill attitudes and desires in consumers
(translation: advertisers are paid to convince people to buy a product ... political strategists are paid to convince people to vote for a candidate)
What's being assumed? How would you object to this?
I like to frame my thinking by adopting the OPPOSITE of the conclusion.
"How would I make the counterargument that democratic elections DO represent the real preferences of people ... that they HAVEN'T been brainwashed?"
I guess I could just argue that maybe the brainwashing attempts by the political strategists fail. Maybe people see right through them and vote according to personally held values and convictions.
So I guess the author is assuming that political strategists SUCCEED in manipulating public opinion.
The Premise only says that they're paid to manipulate the public; it doesn't say they actually do it. The Conclusion is acting like we know they succeed in brainwashing.
Answer Choices:
(A) "Nondemocratic" is out of scope. Eliminate.
(B) This actually might weaken. If people "see right through" advertisers' techniques, they might "see right through" political strategists' techniques. This sounds like the objection I was thinking of.
(C) If anything, this would weaken. If there are limits on political ad spending, then that would place a cap on how much effect those political ads could have in brainwashing the public.
(D) The actual forms of media consumed are irrelevant. It never said that political strategists use TV or print or both or neither.
(E) Huh. Not what I expected, but clearly relevant to the conclusion, because it's talking about "changing voters' beliefs". That's a good paraphrase for "adulterating the preferences of voters".
This choice is making a distinction between "reinforcing existing beliefs" and "changing voters' beliefs".
OH! Now I see another objection we could have made to this argument. We might have said, "advertisers and political strategists may spend money trying to get me to buy product X or vote for candidate X, but what if I was ALREADY planning to buy product X or vote for candidate X? If I ALREADY preferred that product/candidate, then the political strategists aren't ADULTERATING my preference. They're just reinforcing it."
So (E) is ruling out that objection. It's saying, "No, no, no. Although that may be true in advertising, with political strategists, they ARE actually changing voters' beliefs."
I can see how (E) is a confusing correct answer, since the author was making an analogy between advertisers and political strategists. Meanwhile, (E) draws a distinction between them. Normally, pointing out a distinction in two things that were analogized would be what we do on a WEAKEN question.
But in this case, the distinction made about political strategists is something that reinforces the conclusion. Political ads often change voters' beliefs.
If you focus on that half of the sentence, it's easy to see how it strengthens the argument. It sounds a whole lot like the Conclusion!
Hope this helps.
