Read the sentence from an argumentative essay on the Columbian Exchange.

"I believe this was the crummiest part of it all because native people didn't get a say in whether they wanted to work for the mean Europeans."

How should the sentence be revised to include a formal tone?

One negative impact was that native peoples were forced to work for Europeans against their will.
One truly horrible impact that is disturbing is that Europeans brutally forced native peoples to work.
The worst part of it all is that native peoples didn't get a say in whether they wanted to work for the mean Europeans.
We really think it is terrible and heartbreaking that native peoples didn't get any say in whether they wanted to work for Europeans.
