Answer 1

Some of these aren't quite right, but it's a little difficult to know how to correct them without seeing more of the context.

1. The word "evaluated" does not work here. Maybe start with, "According to the evaluation, the total surface..."
2. You need the article "a" in front of "covering. " "Was used as a covering..." I am not sure "covering" is the right word, but I don't know that much about interior decorating terminology.
3. Fine.
4. Not sure what you mean by work "field" but otherwise okay.
5. You should say, "in the purchasing" instead of "for the purchasing."
6. Not sure if this okay; would need to know more.
7. Fine.
8. Rewrite: "Two years after the paint had been used, toxic gases radiated from the paint."
9. The "views" can't "advise." Only people can advise.
10. The word "disrupted" is not right here. I am not sure what you are trying to say here.
11. I would move the word "analyzed" to after "brands," but otherwise this is fine.
