Which one of the following most logically completes

Answer choices

  1. Too Strong: only when4% picked this

    can live happily only when economic utility is not a motivator

    We know that humans can live happily only when love and friendship are the primary motives for action. In order to support this answer, we would have to know that "love and friendship are the primary motives for action only when economic utility isn't a motivator at all". That's way too strong. We need love and friendship to be the primary motives, not the only motives. It's possible for economic utility to be a secondary motive, which still permits living happily.

  2. Too Strong5% picked this

    cannot achieve happiness unless their economic needs have already

    Too Strong: cannot unless Opposite, if anything Beyond being way stronger than anything we could justify, this answer also makes it seem like the requirements of happiness and economic needs are intertwined, but this paragraph made them sound distinct.

  3. Too Strong: cannot3% picked this

    cannot satisfy economic needs by means of interactions with family members

    Why can't interactions with family members / friends potentially satisfy economic needs? Were we told about anything that's required to satisfy economic needs? No, we weren't. All we can say about satisfying economic needs is that you don't need to have love and friendship be the primary motives for actions. It's fine if they are the primary motives; but you don't need them to be.

  4. Correct86% picked this

    can satisfy their basic economic needs without

    Why this is right

    It's the only safely worded answer up here, so that makes it a lot easier to find this correct answer. Is it possible to satisfy basic economic needs without obtaining happiness? Sure! The first sentence that said happiness requires X, and the second sentence said "economic needs can be satisfied even in the absence of this condition". So you can satisfy basic economic needs, even when X is not true, which means that you can satisfy basic economic needs even when you wouldn't be able to obtain happiness.

    Too Strong: cannot unless Opposite, if anything Beyond being way stronger than anything we could justify, this answer also makes it seem like the requirements of happiness and economic needs are intertwined, but this paragraph made them sound distinct.
