Answer:
For the opinion, choose your own, we might have differing ones. The reason, you have to back up your opinion, and for the example, you have to give an example that explains why you have that specific opinion.
Example:
It is important to take action against what I know is wrong because if you see something happening that you do not agree with, it is biblically and morally wrong to stand by and allow it to happen. A reason for this is the fact that we learn from a very young age that being quiet and letting what happens happen is the right thing to do. However, standing up for what we believe in is something that has been pushing the envelope as of late, encouraging people to fight for what they think and what they know is right. An example of when someone could take action against what they think is wrong would be if a group of friends stood up for an outcast when they were being bullied. The group could have simply stood by and ignored the bullying, as the child was an outcast, but instead, they stood up for what they believed in and, in turn, stood up for their classmate. Please do not plagerize this, write your own, man!
