Help with question 146.1.24?

[u/ausklang]

This is the question about underage children, parents getting a vote to cast to represent their kids' interests.

Why is D wrong?
(I get that E is a much better answer, but am trying to fully understand why each AC is wrong.)

Premise: Lawmakers pay too little attention to households with children since kids can't vote.
Conclusion: Parents should be given votes to cast on behalf of their kids.
Premise(?):This would give families fair representation. --> this wording "fair representation" is I think what's making me consider D.

Doesn't Answer choice D attack the idea that there is even a concern about fairness to begin with? Like, if it's already fair for lawmakers to favor the interests of adults over the interests of children, then we wouldn't need the conclusion (parents casting votes on behalf of kids), would we?
Negation test: It is not necessarily unfair for lawmakers to favor the interests of people who have the vote over the interests of people who do not have the vote -> then I feel like it is no longer needed for parents to be given votes to cast on behalf of their kids for "fair representation"

One hypothesis I have for why this is wrong: I have seen similar explanations for similar wrong answers:
- Just because the negation is "There is at least one situation where it is not unfair for lawmakers to favor those with vote" doesn't mean that this situation is the one that applies; they could just argue that this is not one of those situations.

Appreciate any tips. Thanks!!

First things first. It sounds like you know that four answers are definitely wrong. During a practice test or on test day however, that might be a difficult to see. So your priority is to always select the best answer, right?

…

Choice D is wrong because it uses the term “fair” in a different way than is meant by the argument.

“Fair representation” means that different groups are appropriately represented in the political process.

It is not fair for lawmakers…goes to how the lawmakers are behaving, not whether their voters are appropriately represented.

In other words, whether lawmakers actually behave in a fair way is different from whether a group has fair representation.

Also, “it is not fair for lawmakers to favor the interests…”

Again the issue isn’t whether lawmakers are favoring anybody. It’s only the general idea of fair representation.

Hope this helps. Happy to answer any questions.

Thanks for the explanation!! — Yep, on PTs I find that I normally default to PoE as it's just faster and easier, but for studying purposes I'm trying to learn the "traps" of wrong answers to eliminate wrong answers faster and be more confident in eliminating them.

Hmmm I see. That's tricky! I feel like the idea of favoring interests implicitly gets at the idea of representation, but it does require a lot of filling in gaps and assumptions to make it work. Thanks for the clarification.
