Choose at least one answer.

	a. After a while, only you realize that there are no rules of the game; you are making up the rules as you go on.
	b. It is not important that an observer be present as long as the subject was present at the beginning.
	c. The observer does not need to be present in order to collapse the possibilities, and therefore an observer didn't need to be present 14 billion years ago.
	d. Suppose you imagine a game that you are playing with your friends and the only rule that is given is that whatever you say is consistent with all the previous things that have been said about the rules of the game.
