Right, but "evaluated subjectively" matches up with "selecting units of measurement," not with "arbitrarily selected." "Arbitrarily" matches up with "resent" - those are the new words added into the conclusions the stimulus and in (D).
The way I diagrammed each one is as follows:
Science

Measuring

Units of Measurement
Units of Measurement

Arbitrary
therefore,
Science

Arbitrary
Units of Measurement

Arbitrary
(D): Manager

Evaluating People

Evaluation Subjective
Evaluated Subjectively

People Resent
therefore,
Manager

People Resent
I think I see what you're saying now. If it were that people resented the fact that evaluation is subjective, it would match up. But because they resent being evaluated subjectively, it combines statements, because the last statement in the chain is saying that evaluation is subjective - it's describing evaluation. In the conclusion, it's saying that they resent being evaluated subjectively, not just that they resent the fact that evaluation is subjective.
Do I got it?
Thanks, Adam!
