Grammar explanation
Relative clauses give us information about the person or thing mentioned.
Defining relative clauses give us essential information – information that tells us who or what we are talking about.
The woman who lives next door works in a bank.
These are the flights that have been cancelled.
We usually use a relative pronoun or adverb to start a defining relative clause: who, which, that, when, where or whose.
who/that
We can use who or that to talk about people. that is more common and a bit more informal.
She's the woman who cuts my hair.
He's the man that I met at the conference.
which/that
We can use which or that to talk about things. that is more common and a bit more informal.
There was a one-year guarantee which came with the TV.
The laptop that I bought last week has started making a strange noise!
Other pronouns
when can refer to a time.
Summer is the season when I'm happiest.
where can refer to a place.
That's the stadium where Real Madrid play.
whose refers to the person that something belongs to.
He's a musician whose albums have sold millions.
Omitting the relative pronoun
Sometimes we can leave out the relative pronoun. For example, we can usually leave out who, which or that if it is followed by a subject.
The assistant [that] we met was really kind.
(we = subject, can omit that)
We can't usually leave it out if it is followed by a verb.
The assistant that helped us was really kind.
(helped = verb, can't omit that)

Hello Zamra,
You can use both that and which in defining relative clauses.
In non-defining relative clauses that cannot be used.
As far as meaning goes, that can refer to people or things. Which can only refer to things. Other than that, the two are interchangeable. That is more common in spoken English.

Hello abo omar,
It's perfectly fine to use whose with things as well as people, so your sentence is correct.

Hello Kareninoiso,
We don't normally use a relative clause beginning with 'where' after the word 'place' -- instead we use 'that' or just omit the relative pronoun: 'The place I want to visit is Paris'.

Hi Emmanuel,
Yes, that's right! You may need to mark more than one answer for each question (it may not have just one answer).
