Study the theory box. Then, correct sentences (1-6) below, by adding an apostrophe where needed.
We use an apostrophe:

• to show omission of letters in contracted verb forms.

I’m reading a book.

• to show possession.

Peter’s motorcycle, the girls’ house, the men’s car, John and Mary’s scooter, John’s and Mary’s bikes

We DON’T use an apostrophe:

• with possessive pronouns.

This book is yours. (NOT: your’s)

• with years.

the 1990s BUT the ‘90s

Note: it’s = it is or it has BUT

its = possessive adjective​
