People have wondered for a long time how their personalities and behaviors are formed. It is not easy to explain why one person is intelligent and another is not,or why one is (62) and another ’is competitive.
Social scientists are, of course, extremely interested in these types of questions. They want to explain why we possess certain characteristics and (63) certain behaviors.

Proponents of the "nurture" theory, or, (74) they are often called, behaviorists, claim that our environment is more important than our biologically based instincts in determining (75) we will act.

The behaviorists’ view of the human being is quite (77) ; they maintain that, like machines, humans (78) to environmental stimuli as the (79) of their behavior.
Neither of these theories can yet (80) explain human behavior. In fact, it is quite likely that the (81) to our behavior lies somewhere between these two extremes. That the controversy will continue for a long time is certain.

A.respond

B.attribute

C.object

D.tumble
