Well for starters, It’s mostly based on *your* opinion, think of a privilege you have and don’t have but you wish you had (if you want me to create a scenario for you I can)
Perhaps the answer is when Macbeth kills the current king and is rewarded by being named king himself. Nobody expected he would turn bad and kill the king, he was formerly a good soldier, and that is why it is said that 'fair is foul' - he used to be good, but isn't anymore.
Answer:
1. if you don't understand a question you can put it on this site and people will look at your question and they will explain it to you.
2. If other people need help you can explain to them and help them out and then they can understand it. It would be like you are the teacher and a student would be asking you a question and you have to explain it to them very clearly and sometimes you might be the student yourself and then another person ( aka teacher) will help you out.
3.You can get points for explaining a answer and people can thank you for helping them out and you can do the same when other people help you out and when people check your profile they can see that you are good if you have a lot of badges and a lot of points and they will see that you are a person that they can depend on.
