Explanation:

We can use an apostrophe to form the genitive case in English. The genitive case is used to indicate possession. The apostrophe is placed at the end of the name of the possessor:

- Nina's book.

If the same object belongs to more than one person, we place the apostrophe only after the last name. If we have different objects belonging to different people, then we place an apostrophe after each name:

- John and Lara's car.

- John's and Lara's cars.

Even though the apostrophe is usually used with names of people, it can also be used with other names or nouns, which gives them a sense of importance. For example:

- the agriculture of Brazil → Brazil's agriculture.
