Answer: Quid pro quo
Explanation:
Quid pro quo is defined as a favour granted in return for something done. Betty wants promotion and Ben wants to take advantage of her by granting her a promotion on the basis of Betty fulfilling his sexual flavours. This is an assualt and an unfavourable condition for Betty if she doesn't want to and as such promotion should be merit on stands of hardworking and not an immoral favour.
A virtue is a desirable trait that between kindness and cowardice an ethic is like a rule or a decision. To make good or cowardly decisions is what an virtue ethic is. A bad ethic can ruin somebodies with fact that these ethical decisions are made when somebody is in trouble or pain. Good ethics are extreme decsions in protecting the harmed even when it means killing or injuring yourself. My best example would be from the true story turned movie about RED Navy Seals sent to kill an Isis leader and they came across villagers and decided not to kill them because they were young and that cost 3 out of the four men their lives. In the process of dying they saved the fourth dude while aware they were about to kill themselves doing so. Best movies ever! Called Lone Survivor. If there is anything that resembles virtue ethics its what the Arabian guy and his village did to help the lone soldier, putting his life in danger. Hopefully you can summarize off of what I said.
Liberia was not a African Empire, and Belgium had control over modern-day Congo by the 1800s.
