Student or Learner
I did this grammar exercise on the British Council website. My answer is below.
"Debbie has been looking very tired lately. She has been working too hard?"
The second Present Perfect Continuous form was marked wrong. To me, both the Present Perfect Simple and the Present Perfect Continuous work here. I put the Present Perfect Continuous because I think it covers the same period of time as the first sentence. Can anyone please explain why my answer is incorrect?
Are you absolutely sure it was the tense they marked as wrong?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
