The best answer is not going to be hard to choose:
These are examples of 4 hypothetical answers:
Eg.
Answer 1:
Blue
Very simple, plain.
Answer 2:
Blue because blue is the colour of the ocean, the place where i would like to live.
Good answer.
Answer 3:
Blue, because i like melons.
This answer was probably written by someone who felt like being random.
Answer 4:
Woodchuck
This person doesn't even answer the question.
So answer 2 would be the best answer.
