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

Only the right answer will be a conclusion supported by the passage. A “situation” is going to be evidence, just a set of facts. While a “generalization” could go either way, on the LSAT it’s more often a conclusion than support.

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

There is no conclusion in the passage. The right answer will be the conclusion all that supports.

[BACKGROUND]. [SUPPORT]. [SUPPORT].

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

(A) …are actually deleterious to it.

The passage specifically says “greater efficiency”, so this straight up contradicts what we just read.

(B) …benefit workers financially while making their work less rewarding…

This all maps. The “increases in most workers’ standards of living” is what “benefit workers financially” refers to, and “less rewarding” maps to “robbing their work of some of the intrinsic value”. You also gotta love really moderate wording like “Some” and “can” in a conclusion.

(C) …decreases in the amount of effort…

It’s not unreasonable to suppose this is true, but the passage doesn’t actually mention “effort”, so that’s not a valid conclusion to draw.

(D) …will likely involve an accompanying decrease…

The passage only says these two things are happening “At the same time”, it doesn’t touch on the likelihood of anything.

(E) …less efficient than workers who have average…

The passage never compares different “workers” to each other, so we have no basis for this conclusion.

(B) is the correct answer.
