The correct answers are B) cheaper production and C) reduced unemployment.
The achievements made by corporations were cheaper production and reduced unemployment.
Corporations changed the way companies operated and not always this meant advantages for the workers. A corporation is a legal entity that functions separating its operations from its owners. Owners share profits and losses and through the corporation, they have limited liability. Owners hire managers to operate the corporation and they ask results to these managers. Corporations offer jobs but workers are not treated very well. Some times they became dispensable and hire other workers who adapt to what corporations offer.
