Sentence Correction (SC) | Re: More than fifty years after the Second World War, a number of African

Dear Experts,
I have questions about Prepositional Phrase, especially the prepositional phrase at the end of a sentence.


I know that "Prepositional Phrase after Comma" is a modifier. However, I'm not sure whether it modifies the closest noun or the subject.

Examples

1) X replaces Y, instead of Z[ instead of Z modifies X or Y, or it can be both --> ambiguous]

2) X replaces Y instead of Z[ instead of Z modifies Y right? ]

3) X, instead of Z, replaces Y[ instead of Z modifies X right?]

4) More than fifty years after the Second World War, a number of African American soldiers
