(A) should fail your shallow dip on the word should, which indicates a normative conclusion (one issuing a value judgment). That’s a common dynamic you should aspire to recognize when you see it, and it’s absent in the stimulus.

(A)’s conclusion also isn’t causal – a matching version would say:

C: It is good teachers, not [something else], that account for Bryker’s students excelling.

Its structure otherwise matches up quite well with the stimulus’, though, which just heightens the importance of recognizing these common flaws up front.

Ideally you should eliminate the other answers on your shallow dip, then loop back around to (B) to confirm it matches before picking it. As a start, (B) preserves the stimulus’ correlative premises and two causal conclusions. Here’s the full structure:

P1: Every time it Snows [on the highways], there are Hella Crashes.
P2: Hella Crashes means Careless drivers.*
________
C1: Carelessness causes Hella Crashes
C2: Icy Roads don’t cause Hella Crashes.

*Parsing P2 the right way means recognizing “unless” as a group 3 indicator.

(C) fails for two main reasons. First, the word “most” in its conclusion turns it from an absolute claim (about one thing causing another) to a relative claim (about one thing causing another more than other stuff does). This relative vs. absolute mismatch is a common distinction you should aspire to notice when you see it.

Second, (C)’s conclusion introduces the new concepts of rhythm and counting, which don’t appear in the premises. It assumes musicians have rhythm and mathematicians can count which, while reasonable, is still a structural mismatch with the stimulus.

It’s otherwise pretty solid. Better even than it might seem at first, because premise 2 works out if you think about its contrapositive:

P1: All the Musicians [I know] are Good Dancers.
P2: All Good Dancers are not Mathematicians [I know].
________
C1: Rhythm causes Good Dancing
C2: Counting doesn’t cause Good Dancing

Its many structural mismatches aside, (D) should die on your shallow dip at the word must, which indicates a normative conclusion (one issuing a value judgment). That’s a common dynamic you should aspire to recognize when you see it, and it’s absent in the stimulus.

(E) should fail your shallow dip because it lacks one of the causal conclusions. We’ve got “good work doesn’t cause A’s,” but we don’t have a conclusion about what does cause A’s.
