When possessive nouns are used, we can NOT use pronouns to refer back to them.
e.g. Ravi's diary helps him keep track of expenditure. this is incorrect because him can't refer back to possessive "Ravi's diary" form, as if there is no Ravi mentioned at all.
although, this is correct - Ravi's healthy habits keep his posture correct. Possessive pronoun refers back to possessive noun.
Why is
Grisham's mentioned in the non-underline part?
The reason would be because John Grisham (noun) is not mentioned in the non-underline part (mostly because it is present as Grisham's).
John Grisham's stay at the prison inspired him to write several novels; travels [travelers?] can still visit Alcatraz, the model for the prison in one of Grisham's most famous books.
(A)
John Grisham's stay at the prison
inspired him to write several novels
1. here a bit of personification is going on. Stay at prison is inspiring Grisham.
2. "him" doesn't have a noun to refer to
(B) Because of his stay at the prison,
John Grisham was
able to use the
inspiration for several of his novels
1. "Because of his stay at prison" is an adverbial modifier (modifies "was able to"). which is correct
2. John Grisham is the subject here, so there is no need to say Grisham's in non-underline part, can just say "his most famous books"
3. This says -- Without stay Grisham was not able to use the inspiration?
(C) Because of prison,
John Grisham was
able to use the stay as inspiration for several of his novels
1. This says, John was not able to use the say as inspiration without prison.
2. Subject is John Grisham, we don't need Grisham's in non-underline part.
(D)
John Grisham was inspired
to incorporate the stay at prison into several of his novels
1. Subject is John Grisham, we don't need Grisham's in non-underline part.
2. John Grisham was inspired by his stay at prison -- this meaning is missing here.
3. John Grisham incorporated stay into his novels -- this is a new meaning here.
(E)
John Grisham's stay at the prison
served as inspiration for several of
his novels
his can refer back to Grisham's (possessive pronoun to possessive noun)
