Answer choices

  1. Opposite Logic12% picked this

    Companies would hire people with doctorates in the liberal arts if such people were interested in the money

    We were told don't have interest rarely in the financial gain get hired And this is just flipping that idea do have interest will in the financial gain get hired? We won't have proven the conclusion until we know that Dr. Liberal Arts doesn't have concern with financial gain. This answer doesn't establish that.

  2. Too Weak8% picked this

    Some people who are interested in the liberal arts do not

    This is headed towards where we want to go, but since Sufficient Assumption wants a 100% proven conclusion, we need to know (all) doctorates in the liberal arts do not care about money (that can be gained by hard work in business).

  3. Reversed Logic20% picked this

    The only people not interested in making money in the business world are people who are interested

    "The only" is a sufficient indicator (unlike "only" and "only if", which are way more frequently used, and necessary indicators). This is saying not interested in ? interested in making business money improving intellects We wanted the reverse of that. We know that Dr. Lib Arts is interested in improving intellects. We want an answer that allows us to then say that Dr. Lib Arts is not interested in making biz money. But this answer doesn't do that. We can't read the arrow backwards.

  4. Out of Scope: interest in employment3% picked this

    People with doctorates in the liberal arts are interested in employment in

    Sufficient Assumption correct answers almost never introduce new language into the conversation. We were never talking about who was / wasn't interested in employment. If we knew that Dr. Lib Arts was not interested in business employment, that would strengthen (though not prove) the idea that companies rarely hire Dr. Lib Arts. This answer actually goes the opposite direction, so it almost weakens. But more importantly, it's not giving us the clear trigger we need: it doesn't give us a way to say that people with doctorates in liberal arts are not concerned with the financial gain of the business world.

  5. Correct57% picked this

    Only people not concerned with making money in the business world are interested in

    Why this is right

    "Only" and "Only if" are necessary indicators, so "people not concerned" goes to the right of the arrow. interested in not concerned with improving intellects ? making $ in biz world This is what we predicted. Here's a look at how the correct answer adds onto the evidence to derive the conclusion. Prem1: ppl with Dr's in LA are interested in improving intellect. This answer: ppl interested in improving intellect are not concerned with making money in the business world. Inference: ppl with Dr's in LA are not concerned with making money in the business world. Prem 2: companies rarely hire people not concerned with making money in the business world. Conc: so companies rarely hire people with Dr's in LA

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