A professor gave me a project, and now he wants me to update the the progress of the project I am doing. I wonder if I can use the simple past "What did you do on the project" to imply so far in AmE:
The professor: How is your project? What did you do on the project so far?
Me: I only finished the first part of the project, I am going to proceed to study the next part tomorrow.
The question should be
(1) What did you do on the project (so far-imply)? or
(2) What have you done on the project (so far-imply)?
(3) Which part of the project did you finish (so far-imply)? or
(4) Which part of the project have you finished (so far-imply)?
I know that BrE definitely uses the present perfect. AmE also uses present perfect. I know that AmE tend to use simple past instead of the present perfect I don't know if AmE uses the simple past in this context.
