Hi Karlie, thanks for flagging! This looks like old "partner" content, i.e. not written by Khan Academy, and certainly not by our science content experts! You're right though, we certainly need to fix it, so thanks for bringing to our attention! Will update ASAP. Thanks again.
Update: We've removed and replaced this question! Thanks again for alerting us, please let us know if you spot any other errors!
