So I've spent an inordinate amount of time trying to analyze this question, especially answer choices B, C, and D. I incorrectly chose C.
Here is my take on the tempting incorrect answer choices:
C is wrong, for one thing, because no change in situational factors DOES NOT MEAN that the code-switching is not situationally determined. For example, we can have the same participants, topic, and setting (i.e. no change) and the code-switching that occurs could still be explained by situational factors. Secondly, that "bilingual people often switch smoothly between two languages" is pulled from the start of the passage that is still describing code-switching without yet making any claims as to why this is. It combines that part with the phrase "with no change in situational context" to force the reader to associate it with the third paragraph. Therefore, C is a statement that actually isn't made in the passage, much less offered as evidence that code-switching cannot be entirely explained by situational factors. Admittedly, I chose C because of that "no change in situational factors" phrase but I realize that phrase is associated with the ONE family in the one study who code-switched OCCASIONALLY with no change in situational context, so C overgeneralizes in saying bilingual PEOPLE OFTEN code-switch with no change in situational context, which cannot be inferred from the study alone.
Now D. I didn't initially have a problem eliminating this until the discussion above prompted me to think harder about my reasons for eliminating it. I believe that D is wrong because the claim the "code-switching cannot be entirely explained by situational factors" supports D in a way, not the other way around.
If we broke down paragraph 3's argument core, it would be:
Premise: Code-switching occurs when situational factors lead one not to expect it.
Intermediate Claim: Code-switching cannot be entirely explained by situational factors.
Conclusion: Rhetorical factors can explain code-switching where situational factors can't.
Premise: Study of Puerto Rican American family indicating rhetorical reasons.
The claim that code-switching cannot be entirely explained by situational factors paves the way for the rhetorical explanation (the overall argument of paragraph 3), rather than "example of rhetorical code-switching --> code-switching not all situational."
Also, D is wrong because code-switching that situational factors predict would occur in a different language mix is NOT the same thing as code-switching that situational factors predict would not occur at all, which is the actual evidence used and stated in credited response B.
I hope I'm on the right track, I spent all morning trying to dissect it.
