I hate to be a pedant (that’s a lie, I love it!), but you missed the a out of supernAtural, it’s just irritating me because once I spotted it I can’t help but notice it, if you follow.
As you well know, it’s a dangerous route to tread , we can’t let grammar and spelling get in the way of correct answers, personally I highlight all mistakes but don’t take it into account during the marking process, although I probably should have a seperate SPG mark and monitor the “improvements” over the course of the year to enhance my “literacy in science” for my CPD. Oh well, life sucks. I also know lazy English teachers who don’t correct grammar and spelling!
