"Outside is very cold" should be accepted

"Outside noodles is cold"? I really don't get all these "classifiers"

I really can't stay.

It is cold out.

If you go to the word bank, there is no 'very' in there

"我得走了"

simply "wei" you use hen u specify outside of "what" youre talking about? is that the defference?

It is cold FROM outside should also be CORRECT.
