1. these are the hats of the team. these are the teams hats.
2. the shirt of my sister is green.
3. this is the food of the birds.
4. the sons of brad are tall.
5. the horns of the cars are loud.
6. the room of my brothers is big.

Explanation:

For sentence 2, “my sister” is singular, so we use “sister's” to show possession. In sentence 3, “birds” is plural (ending with -s), so we add an apostrophe (’) to form the plural possessive “birds'”. For sentence 4, “Brad” is singular, so “Brad's” is correct. In sentence 5, “cars” is plural (ending with -s), so “cars'” is used. In sentence 6, “my brothers” is plural (ending with -s), so “brothers'” is the right form.

Answer:

1. My sister's shirt is green.
2. This is the birds' food.
3. Brad's sons are tall.
4. The cars' horns are loud.
5. My brothers' room is big.
