All highly successful salespersons are both well organized and self-motivated, characteristics absent from many salespersons who are not highly successful.

Statements

There are a handful of Conditional quantifiers (All, only those, no) and one non-conditional quantifier (many). The latter is our last priority. We should first think about how these conditionals would look, and see if there are any overlapping terms that would allow the conditionals to chain together.

Highly successful → well organized and salesperson self-motivated

~Highly successful → ~well known among salesperson peers

Self-motivated → does not regret salesperson career choices

Do any of these chain together? Yes, the first two should, since they both deal with highly successful salesperson and we have OPPOSITE ideas on the SAME side. If we contrapose the 2nd rule, we'll get this chain.

Well known → highly succ → well organized + among peers salesperson self-motivated

There is also an Overlapping Idea with self-motivated appearing in the first and last claim. We can actually chain on one more idea.

Well known → success → motivated → ~regret

What about the "many" fact? Many ~highly successful are ~well organized salespersons & ~self-motivated

Do either of those ideas trigger anything? Yes, we know that if you're not a highly successful salesperson, then you're not well known among your peers.

So we could derive a Trait Overlap: many people who are not (well organized) and not (self motivated) are also not well known.

Goal

Look for an answer rewarding chaining together the three conditionals (connecting "well known" with "organized/motivated" or "doesn't regret career choices") or an answer giving the Trait Overlap inference of not organized / not motivated paired up with not well known.

If all of the statements above are true, which one of the following must be true?

  1. No self-motivated salespersons who are

    Unsupported Relationship

    This says: self-motivated salesperson not well and ? organized not highly successful We only have a way to prove people are well-organized. There's no rule that allows us to say "anyone who has this quality is not well organized".

  2. All salespersons who are well

    Unsupported Relationship

    This says well organized and ? self-motivated not highly successful We only have one way to prove "self-motivated", and that's knowing that someone is a highly successful salesperson. If the salesperson in this answer choice is not highly successful, then we have no idea if they're self-motivated.

  3. Correct

    No salespersons who are well

    Why this is right

    This says, for salespersons ... well known ? don't regret career choices We can derive this. Well known salespersons are always highly successful. Highly successful ones are always self-motivated. Self-motivated ones never regret their career choices.

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

  4. All salespersons who are not

    Unsupported Relationship

    This says, for salespersons .. not well organized ? regret career choices We only have a rule that allows us to say that you don't regret career choices (if you're self-motivated). We have no means of deriving that anyone does regret career choices.

    4% picked this

  5. All salespersons who do not

    Unsupported Relationship

    This says, for salespersons ... don't regret ? highly successful career choices The only mechanism we have for proving "highly successful" is knowing that a salesperson is well-known. Do we know that "if you don't regret career choices, you're well known"? No. So, we have no means to get from "don't regret" to "highly successful".
