You copied most of the article from the link I gave you and changed a few words. I didn't check to see the last part of the article but this is not accepted by the SteemSTEM standards.
You can't expect to copy an article from somewhere else and still be paid for it.
You have the chance to rewrite the article so it will comply with the rules.
Refer back to the information I have given to you and the discussion we had on Discord. It would be a shame to have talked for two hours for nothing.
I think you can still turn the article into an original and worthy one as the subject is clearly interesting.
