I can see you’re inundated with questions here. Sorry to drop another on your lap.
In your conclusion you didn’t use ‘opinion’ words, but rather stated the conclusion as though it were a fact . you didn’t say “in my opinion”..
I infer that you think this is ok, even though I steer my students away from this. Are you working on the basis that it’s implied that it’s your opinion or in fact, do you believe it’s a fact.
[Interesting to note your use of rephrasing twice (body para’s 2 and 3)]
PS I’m a Kiwi. How did you find NZ?
