Answer:
Just revise the passage, like it says. Replace some words, spruce it up a bit. Make sentences more formal than they are informal.
Explanation:
For example, in the sentence "stop them from bringing products in," you could say "stop them from importing products." Just find a good spot for the words export and blockade, like it tells you to. Review every single sentence - How can you improve them, or make them sounds better?
You will need to provide the text that you are analysing for a specific answer, but basically, you are looking for any time where the author has used describing words that you would use for humans on object or animal, or where the author is making the object/animal use human characteristics like speech.
the effect that this may have on the piece could be that it creates a friendlier atmosphere if the object/animals are described in a positive and useful way but it can work in reverse as well.
So much is at stake in writing a conclusion. This is, after all, your last chance to persuade your readers to your point of view, to impress yourself upon them as a writer and thinker. And the impression you create in your conclusion will shape the impression that stays with your readers after they've finished the essay.
I’d believe the informal would be “Can you...?”
