Tutorial step 2 says "The controller scope is a prototypically descendant of the root scope.."
I'm not sure what that means, seems like there's a word missing.
"... that was created when the application bootstrapped."
Passive voice is lifeless and without an agent it makes it harder to understand. Maybe "... that the AngularJS injector created at bootstrap".
👍 but we changed the tutorial a couple times over the past year, so I'm not sure this exact text remains.
If you can find it, feel free to send a PR. Otherwise, we are indeed avoiding passive voice in our docs now.
