Dear ron,
there is a sentence: on the stage is Professor Y, along with professor X, who recently won a NP for his work. This is a sentence I see in your previous online class. Could you please tell me why does the who....modifier modify the professor X not the professor Y? Also, in a construction: NOUN+ Modifier1+ Modifier 2, in what circumstance, the modifier2 modifies the NOUN rather than any noun included in the modifier1?
Thanks in advance
