The conclusion follows logically if which one of the following

Answer choices

  1. Unrelated to Goal9% picked this

    Whoever loves someone loves

    We're trying to attach "receiving love" to "giving out love". This is linking "giving out love to one" to "giving out love to all".

  2. Unrelated to Goal6% picked this

    Whoever loves everyone loves

    We're trying to attach "receiving love" to "giving out love". This is linking "giving out love to all" to "giving out love to one". This answer is also a tautology (a self-defining truth). Naturally if you love everyone, then you love "at least one person". That doesn't ever need to be said or assumed. It's just self-evidently true.

  3. Unrelated to Goal7% picked this

    Whoever is happy loves

    We're trying to attach "receiving love" to "giving out love". This is linking "giving out love" to "being happy". If we're ever confused on Sufficient Assumption, one guessing heuristic that works pretty well is to not guess any answer choice that uses an idea that showed up twice in the argument. Mentioned twice? That'll suffice The correct answers want to link together stuff that was only mentioned once but not connected to its intended place. Things mentioned twice have usually been connected to their intended places. So in this problem, since "kind" and "happy" both occur twice, we wouldn't expect the correct answer to use the terms "kind" or "happy".

    Why this is right

    You just know that this test writer was proud of him/herself for making such a funny sounding dramatic correct answer. We're trying to prove that if you're kind, you're happy. We know that if you're kind, then someone loves you. According to this answer choice, if someone loves you, then you must love someone (if you loved no one, then no one would love you). And we know that if you love someone, you're happy. Thus, we've proven that if you're kind, you're happy. More formally, this answer is saying Don't love ? Not loved by someone someone The contrapositive: Loved by ? Love someone someone Kind ? Love someone Love ? Loved by someone someone Loved by ? Happy someone Kind ???????????????????> Happy

    Skill tested: Sufficient Assumption · how this choice captures the argument's function is the move to repeat next time.
