who,which

Yesterday I saw someone-------- was selling beautiful paintings

This is a book------ I have been looking for an hour

That's the man -----organised that exhibition

This is the skarf------I bought for my sister

That's the girl ------ I met two days ago

Tom is the man ----owns the restaurant

Owls are animals---don't sleep at night

Give me the keys-----I left on the table

Let me introduce you to the girl-----I met at the party

This is the fast food restaurant-----opened last year
