Can we find a part in the passage that's discussing a visitor from China speaking with a Chinese-American who speaks the same traditional dialect?
It looks like lines 29-37 are the most apt, because lines 31-33 give us the keywords of "new arrival from China" / "Chinese-speaking Chinese Americans" / "speak the same traditional dialect".
In that vicinity, do we talk about where it would be DIFFICULT to converse? Line 29-33 is saying "normal conversations can be conducted fairly readily". But lines 33-37 deal with where there might be problems.
- "terms not familiar to the newcomer ... most of which would name objects, places, and events that are part of the local experience" can be avoided or explained.
So we'd be looking for an answer that sounds like "objects, places, and events that are part of the local (American) experience".
Of the five choices (C) is the closest match for that idea.
Hope this helps.
