How will the right answer fit in terms of support and conclusion?

Only the right answer will NOT have the same kind of facts/background as in the “Situation” in the passage.

Highlight the main conclusion in the passage, if there is one:

There is no conclusion in the passage, since no support is actually given for the “Analysis”.

Situation: [BACKGROUND]. [BACKGROUND].

Analysis: [BACKGROUND / pseudo-CONCLUSION].

So far in the whole history of LSAT PrepTests, this is the only question framed this way. So let’s not get too hung up on the weird tags. Just map the answers to the passage the same way you would on a “parallel” or “most similar” prompt.

Map the wording of the answers to the wording of the passage:

(A) …understand mathematical principles…apply these principles…

Would “success” in understanding principles bring about “success” in applying those principles? I think any reasonable person would say yes.

(B) …customers to be more satisfied…place fewer calls to the service rep…

Would “success” in satisfying customers bring about “success” in having fewer customer service calls? For sure.

(C) …fewer of the books…to be lost or stolen…books to be returned on time.

Would “success” in losing fewer books bring about “success” in more books getting returned on time? No doubt.

(D) …to construct a new, larger warehouse…plan how the old warehouse will be expanded…

Would “success” in constructing a new warehouse bring about “success” in planning how to use the old one? Mmm, that’s highly questionable. Definitely not as direct a link as the others.

(E) …present a more varied repertoire…attract new patrons.

Would “success” in presenting more variety bring about “success” in attracting new patrons? Sure, since you’re more likely to have something for everyone.

(D) is the correct answer.
