• Answer:

  The reason for homework is to get you used to using your brain and researching the questions to get the "right" answer. You learn all sorts of things along the way. The biggest loser is in fact yourself! When you go for job interviews a few questions will show that your knowledge and ability to win in the modern world is minimal. Hence no decent job! Take pride in having done it all yourself!
