I've just started learning English grammar. I have a book with a lot of grammars. There is a unit for present continuous and there is an exercise in which the reader should write sentences based on a picture. Here it is.
In the Key To Exercises section of the book it's stated that the answers for 3 and 7 (marked in the above picture with semitransparent red circles) are: She is sitting on the floor and She is wearing a hat.
But I think She isn't sitting on the floor and She isn't wearing a hat are the answers.
Isn't present continuous for activities that are getting done and are not finished yet? I think Jane has worn a hat, and she is not in the middle of wearing activity. Another alternative may be She has a hat on her head.
