For your #4 thing, say again what it is, and explain why it…
Questions
Fоr yоur #4 thing, sаy аgаin what it is, and explain why it is "impоrtant" - why did you put that thing on your list? Then provide "evidence" of where/when you learned the thing or practiced the skill. See the example in the instructions and make sure to provide enough detail so that we can find it in one of our ebooks, in Canvas, or in the course lectures or videos. Alternatively, use the toolbar to upload a screenshot that shows enough detail that it is clear where it came from. Of course, we likely learned or practiced the thing more than once throughout the semester, but I am only requesting one piece of evidence.
