Question

1. What was your parents' dream?
1-1. They all wanted to be a singer.
1-2. They all wanted to be singers.
(Which answer is correct? Do I have to use a singular noun or a plural noun?)

2. What did you give to your parents on Parents' Day?
2-1. I gave them a flower.
2-2. I gave them each flower.
2-3. I gave them flowers.
2-4. I gave them some flowers.
(Which answer is right? )

3. You can go back home tomorrow afternoon after class. We are going to play soccer with co-workers on the playground. Don't forget to bring sneakers and sports clothes (upper sports clothes and lower sports clothes). We will have a soccer game with other members in the playground.
It seems that it will be warmer tomorrow. However, it is not so hot, so we can enjoy playing soccer together.

(Would you like to check the passage? Correct the errors,please.)

Answer 1

1-1 You could say "They each wanted to be a singer" (each is singular and so is singer)
1-2 is better than 1-1 as you have it.

2-2 = I gave them each a flower. OR I gave each of them a flower.
The rest are fine.

"on the playground" but I'm not sure what "upper sports clothes and lower sports clothes" really means. (shirts and pants/trousers?)
