  1. Correct58% picked this

    Most gardeners are people with a great deal of patience. Since most of Molly’s classmates are gardeners, at least one of Molly’s classmates must

    Why this is right

    -Most of Molly's mates are gardener's Most A's are B -Most gardener's are people w/ patience Most B's are C -So, some Molly's mates are Some A's are C people w/ patience As is often the case, the chronological order of ingredients is scrambled. The "since X, Y" form tells us that Y is the conclusion. We should be proactively looking to arrange the two Most claims so that the first one ends where the second begins.

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

  2. Weak Conclusion Match19% picked this

    Most of Molly’s classmates are gardeners. Since most gardeners are people with a great deal of patience, some of Molly’s classmates could be people

    This one is very close (almost identical to A), but the conclusion doesn't have the same strength as the original argument. Original conclusion: at least one C-employee must receive great salary. This conclusion: at least one Molly's mates could be people w/ patience. This isn't a flawed argument, because, sure, it's possible that there's some Trait Overlap. Our only objection to the original argument is that there isn't mandatory overlap.

  3. Weak Conclusion Match13% picked this

    Most gardeners are people with a great deal of patience. Since most of Molly’s classmates are gardeners, at least one of Molly’s classmates who

    Most of Molly's Most A's are B mates are gardener's Most gardener's are Most B's are C people w/ patience Looks good so far, but this should be the conclusion. So, some Molly's mates are Some A's are C people w/ patience Instead, we get a more complicated conclusion. So, some Molly's mates who Some A's who are are gardener's are people w/ patience B are C This is flawed in the same sense as the original, because the conclusion thinks there must be a Trait Overlap, when there does not have to be. But the structure of the conclusion is different, so (A) is the most similar pattern.

  4. Bad Premise Match5% picked this

    Most gardeners are people with a great deal of patience. Since most of Molly’s classmates who garden are women, at least one female classmate

    We were looking for two most claims, one of which begins the way the other ends: Most A's are B's. Most B's are C. Here, the premises do not have that match. Most gardener's are people w/ great deal of patience. Most of Molly's mates who garden are women.

  5. Bad Premise Match Valid Logic5% picked this

    Most of Molly’s classmates are gardeners with a great deal of patience. Since most of Molly’s classmates are women, at least one female classmate

    We were looking for two most claims, one of which begins the way the other ends: Most A's are B's. Most B's are C. Here, the premises do not have that match. They both start with the same group. Most of Molly's mates are women. Most of Molly's mates are gardener's w/ patience. In fact, this answer is valid logic. Since both Most claims are about the same group (Molly's classmates) there must be at least some overlap between the two ending ideas (gardener with patience / woman).
