You and your friend play a video game where a superbird has to find and eat radiation leaks at nuclear power plants before the plants explode. Which of the following is the main idea of this video game?
Radiation leaks are dangerous
A superbird saves the world
Bird with superpowers
Nuclear power plants

i guess you are missing the idea that has to be supported, am i right?

"it's more of an essay than story, but perhaps it is best described as a mood-piece: it uses a lot of musical imagery, not to mention sea imagery, religious imagery, and any other imagery that suits his purpose."

the answer you're looking for is to review what went well and learn how to do it better next time

demonstrative would be the answer.
