1. What happens if I've already pushed my repo to the grading server, but then I create a new repo from scratch and try to push it?

2. Here are some commands discussed in class:

   • emacs
   • git checkout (you can ignore this one)
   • git add
   • git commit
   • git pull
   • git push

   Write which of the above commands (zero, one, or many) changes which of the following sections of git repository. For instance.

   • Working directory
   • Staging area
   • Local repository
   • Remote repository
