Lesson 5: No solution listed for “Reverting a Commit” exercise

[chennesy]

The Reverting a Commit exercise in the Exploring History section does not currently have a Solution section. This exercise is a fill-in-the-blank question, and some students might guess any number of incorrect answers based on commands learned during the lesson above (git diff, git status). It would be helpful, then, to provide a solution along with a brief explanation. Here’s a proposed solution:

Jennifer could look at the project’s history of commits, including full identifiers with:
git log

For a shorter list, with short identifiers for each commit, she could use:
git log --oneline

If Jennifer is sure her last commit to the repository was the most recent commit by the group, she could also find the commit identifier by looking at the repository’s HEAD:
git show HEAD

My learner just ran into this and it caused a lot of confusion.
