Science is an enterprise concerned with
gaining information about causality, or the relationship between cause and
effect. A simple example of a cause is the movement of a paddle as it strikes a
ping-pong ball; the effect is the movement of the ball through the air. In
psychology and other sciences, the word "cause" is often replaced by the term
"independent variable". This term implies that the experimenter is often "free"
to vary the independent variable as he or she desires (for example, the
experimenter can control the speed of the paddle as it strikes the ball). The
term "dependent variable" replaces the word "effect", and this term is used
because the effect depends on some characteristic of the independent variable
(the flight of the ball depends on the speed of the paddle). The conventions of
science demand that both the in A. one’s behavior can be predicted by knowing his or her birthday B. nobody can choose his or her date of birth as he or she wishes C. an individual’s performance is irrelevant to his or her birthday D. a person’s level of performance varies according to the test date

In science the meaning of the word
"explain" suffers with civilization’s every step in search of reality. Science
can not really explain electricity, magnetism, and gravitation; their effects
can be measured and predicted, but of their nature no more is known to the modem
scientist than to Thales who first speculated on the electrification of amber.
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, 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 A. to explain why things happen B. to explain how things happen C. to describe self-evident principles D. to support Aristotelian science

Passage Four
The remarkable progress of science and technology in the 20th century has brought enormous benefits to humankind. Long and healthy lives, economic prosperity and a pleasant and convenient living environment have resulted from technological progress based on advances in scientific knowledge. This progress will continue or may even accelerate in the future, because both the number of scientists and their activities are expanding throughout the world. We may expect, therefore, that science and technology will continue to contribute to the development of human society.
At the same time, rapid scientific advances may raise some difficult problems. First of all, the disparity in scientific knowledge between those in scientific and technical professions and those in other areas will continuously expand. This may create a communications gap between the two groups that could affect obtaining public consent on important issues, such as the use of genetic A. may cause the lack of scientists throughout the world in the century to come B. is mainly due to the explosion of scientific information C. may increase the communications gap between young people and scientists D. may hinder the development of human society
