Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we ______.
A.have too many conflicting theories
B.do not have enough funding to continue our research
C.are not sure how the universe is put together
D.have focused on investigations of the moon and planets

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.

When my turn came, I explained the situation sorrowfully to the assistant. The man looked at me suspiciously as if to say that he had heard this type of story many times and asked me to describe the case. I told him that it was an old, brown-looking object, no different from the many cases I could see on the shelves. The assistant then gave me a form. and told me to make a list of the chief contents of the case. If they were correct, he said, I could take the case away. I tried to remember all the articles I had hurriedly packed and wrote them down as they came to me.
After I had done this, I went to look among the shelves. There were hundreds of cases there and for one dreadful moment, it occurred to me that if someone had picked the receipt up, he could have easily claimed the case already. This hadn't happened fortunately, for after a time I found the case lying on its side high up in a comer. After examining the articles inside, the assistant was soon satisfied that it was mine and told me I could take the case away. Again I took out my wallet: this time to pay. I pulled out ten-shilling note and the "lost" receipt slipped out with it. I couldn't help blushing and looked up at the assistant. He was nodding his head knowingly, as if to say that he had often seen this happen before too!

"We're more than halfway (中途) now; it's only two miles farther to the tavern (客栈) ," said the driver.
"I'm glad of that," answered the stranger, in a more sympathetic way. He meant to say more but the east wind blew clear down a man's throat if he tried to speak. The girl's voice was quite attractive; however, later he spoke again.
"You don't feel the cold so much at twenty below zero in the Western country. There isn't such damp chill (潮冷)", he said, and then it seemed as if he had blamed the uncomplaining young driver. She had not even said that it was a bad day, and he began to be conscious of a warm hopefulness of spirit, and sense of pleasant adventure under all the woolen scarves.
"You'll have a cold drive going back," he said anxiously, and put up his hand for the twentieth time to see if his coat collar was as close to the back of his neck as possible.
"I shall not have to go back!" cried the girl, with eager pleasantness. "I'm on my way home now. I drove over early just to meet you at the train. We had word that someone was coming to the tavern."

B.About four miles.
C.Two miles.
D.Less than four miles.
