Relative Clauses 6

ANSWERS 1: THAT SHE BOUGHT IN PARIS
That is used after a noun as a relative pronoun like who, whom, or which to introduce a clause. In non-defining relative clauses, who/which may not be replaced with that.
More Examples:
Chris, that I met last year, is very nice. X
Chris, who I met last year, is very nice. V

ANSWERS 2: NONE OF WHOM ARE | NONE OF WHOM IS
A quantity phrase with whom is placed at the front of the modifying clause and then the clause is placed directly after the noun it modifies: none of whom, all of whom, neither of whom etc.
More Examples:
I've got a lot of friends, none of who smoke cigarettes. X
I've got a lot of friends, none of whom smoke/smokes cigarettes.V

ANSWERS 3: WHICH THEY'VE HAD | WHICH THEY HAVE HAD
Which is often used, after a comma in writing, to add more information about the thing, situation, or event you have just mentioned.
More Examples:
One of the girls kept laughing, that annoyed Liz intensely. X
One of the girls kept laughing, which annoyed Liz intensely. V

ANSWERS 4: WHERE YOU CAN BUY | IN WHICH YOU CAN BUY
Where is often used as a relative pronoun. Where means in or to which place. In formal English, a phrase with preposition + which (at which, in which) can often be used instead.
More Examples:
She wanted to get to Dublin, where her sister lived there. X
She wanted to get to Dublin, where her sister lived. V

ANSWERS 5: FROM WHOM WE BORROWED
Preposition + whom. In formal or written English, the preposition is often placed before the relative pronoun, and in this case the pronoun cannot be omitted. Notice that after a preposition you can't use who instead of whom.
More Examples:
Alice, to who I talked just now, sends you her regards. X
Alice, to whom I talked just now, sends you her regards.V formal
Alice, who I talked to just now, sends you her regards.V less formal

ANSWERS 6: WHOSE DAUGHTER HAD BEEN KILLED
Whose is a possessive pronoun like his, her and our. We use whose to find out which person something belongs to.

ANSWERS 7: WHO VISITS THE MUSEUM IS | THAT VISITS THE MUSEUM IS
Who is a relative pronoun used after a noun or pronoun to show which group of people you are talking about. Use who when a sentence requires a subject pronoun (equivalent to he or she). In defining clauses, you can use that instead of who, whom or which.
More Examples:
Do you know the people which live next door? X
Do you know the people who live next door? V

ANSWERS 8: WHOSE COVER IS

Do not confuse whose with who's. We can also use whose when we are talking about things.
