Help the detective complete her interview notes by dragging the correct verb forms into the gaps.

"You look absolutely exhausted, and your shoes are covered in fresh mud. What exactly have you been doing all morning? I know for a fact that you haven't been sleeping, because your bed is perfectly made!"

What exactly have you been doing all morning?

We use the present perfect continuous (have/has been + verb-ing) to ask about a recent, ongoing activity that has a visible result in the present (like looking exhausted and having muddy shoes).

I know for a fact that you haven't been sleeping...

The present perfect continuous emphasizes the duration of an ongoing action (or in this case, a non-action) leading up to the present moment.
