The book 'English Grammar in Use, Murphy' contains the following exercise under the Present perfect/Present perfect continuous chapter:
- Are you OK? You look as if ____ (you / cry).
I have not found any explanations why 'have been crying' is the correct answer.
Based on my understanding, the action has already been completed (the person has cried and now we're asking her by focusing on the result of the action). Other words, I can't imagine a situation when we're asking someone who's crying right now by focusing on the activity and not the result.
Would anyone explaining the Present Perfect Continuous choice here?
