I got this wrong because I didnt realize that I COMPLETLEY skipped over the "physiological" part of the paragraph...

@IsaacLuo yooooo im cryingggggggg

@JessHyder The difference between C and E is that C merely provides support for the stimulus instead of being rejected by the stimulus like E is (anti-supported).

C is claiming that the law offers no protection from 2nd hand smoke outside the workplace, the passage is simply confirming this idea. Therefore, C wouldn't be rejected by the stimulus because it doesn't fall on the anti-support side of the spectrum, as E does.
