听力原文:M: Good morning. Say, do you know what the assignment is for our term paper in history?
W: Sure. Weren't you in class on Monday? That's when it was given out.
M: No, I missed that class. Was there a handout?
W: No, the instructor just wrote the assignment on the board.
M: Could I copy the assignment from your notes?
W: You could, ff I had copied it all down; but I just wrote down the part that I wanted.
M: Oh, no.
W: You see, there were four choices of topics ior the term paper; but, when I saw them, I knew which one I wanted so I didn't copy the others down.
M: Can you remember any o'f the others?
W: Let's see. There was one about World War I, something about it, but I don't remember what, and there was one called "the idea of progress in the nineteenth century."
M: And what was the last one?
W: I can't remember. My mind is a complete blank. Maybe you can ask someone else.
M: Yes, I will. Anyway, those are certainly broad topics.
W: Yes, but you van focus on a special area within them. Which one would you take?
M: Of course, I don't know what the last one is, but of these three, I think I'd take "the idea of progress."
W: That's very abstract.
M: Yes, but it's one of my interests and I've read a lot on the subject. I've never written a term paper on it though.
W: Me neither. I haven't even read about it. Are you going to class on Wednesday?
M: Yes.
W: Maybe he'll write it on the board again.
M: I hope so. Good luck with your paper.
W: Same to you.

In science the meaning of the word "explain" suffers with civilization's every step in search of reality. Science cannot really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modern scientist than to Thales who first looked into the nature of the electrification of amber, a hard yellowish-brown gum. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces "really" are. Electricity, Bertrand Russell says, "is not a thing, like St. Paul's Cathedral; it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell." Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believe that man could arrive at an understanding of reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can deduce that objects fall to the ground because that's where they belong, and smoke goes up because that's where it belongs. The goal of Aristotelian science was to explain why things happen. Modem science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment which now forms the basis of scientific investigation.
The aim of controlled scientific experiments is ______.

A. to explain why things happen
B. to explain how things happen
C. to describe self-evident principles
D. to support Aristotelian science
