Passage One
All that we really need to plot out the future of our universe are a few good measurements. This does not mean that we can sit down today and outline the future course of the universe with anything like certainty. There are still too many things we do not know about the way the universe is put together. But we do know exactly what information we need to fill in our knowledge, and we have a pretty good idea of how to go about getting it.
Perhaps the best way to think of our present situation is to imagine a train coming into a switch yard(调车场). All of the switches are set before the train arrives, so that its path is completely determined. Some Switches we can see, others we cannot. There is no ambiguity (不明确) if we can see the setting of a switch; we can say with confidence that some possible futures will not materialize (实现) and others will.

A. A statement illustrated by an analogy.

Where do these ideas come from Max Luscher from the University of Geneva believes that in the beginning life was dictated by two factors beyond our control: night and day. Night brought passivity, and a general slowing down of metabolism; day brought with it the possibility of action, and increase in the metabolic rate, thus providing us with energy and initiative. D
A. Dark blue brings tragedy.
B. Dark blue means tradition.
C. Dark blue represents night.
D. Dark blue indicates quietness.
