| 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. testify their complete conformity with general scientific principles B. justify the identity of dependent, independent, and intervening variables C. specify the time periods of bodily cycles in terms of psychological tests D. verify their prediction by variables inconsistent with conventions of science [单项选择]使用滤纸式烟度计测定柴油机烟度时，需将探测器头插入排气管内（），并固定。
