Hello, my name's Henry. I've got a question to make:

Could I change "her" for "their" ?

Thank you in advance.

Best regards

Henry

I think you could Henry. both answers seem like they would be correct.

I disagree.

I would definitely not say "Their hand shot up...".

Why the correct answer is 'her' and not 'their'?

[Yankee]

Hi Saneta

"Her" is the only one of the choices that is grammatically and logically possible.

If you used "their", the reference would be to more than one person and the word "hand" would then have to be plural as well.

Of course, the good remark Yankee. Thank you!

Her hand shot up= she raised her hand?
