I've never seen anyone write "Those're."

In what way do you want them clarified?

Thanks.

You're welcome!

2 and 4 are more natural.

Amy: Whose blouse is this?
Beth: It's mine.

Abe: Whose socks are those?
Bob: They're yours.

2 and 4 are more natural.

Amy: Whose blouse is this?
Beth: It's mine.

Abe: Whose socks are those?
Bob: They're yours.

I thought answers should be corresponding to the questions that Beth should say "This is mine." and Bob should say "Those are yours."

Could you explain?

Thanks.

Those I want to clarify are in post 4.

Using your words as much as possible, I was providing you with natural sentences (things people might actually say).

It's invented dialogue but real world conversations.

I'm not sure what I'm supposed to explain.
