Are these sentences natural? November 16

Hi,

Are the following sentences natural to a native ear?

1. You have to come up with a plan in consultation with other group memebers.

2. She must be talking now, right? ( I was talking with a mom about her child, on the phone )

3. I am not in the office today due to some emergency at home.

Thanks,
MG.

Yes.

(I prefer an emergency)

Yes.

(I prefer an emergency)

I prefer "an emergency" too. To me "some" indicates something unimportant; an emergency isn't unimportant.
