　　There are two factors which determine anindividual's intelligence. The first is the sort of brainhe is born with. Human brains differ considerably ,some being more capable than others. But nomatter how good a brain he has to begin with, anindividual will have a low order of intelligence unlesshe has opportunities to learn. So the second factoris what happens to the individual— the sort ofenvironment in which he is brought up. If an individual is handicapped(不利) environmentally, itis likely that his brain will fail to develop and he will never attain the level of intelligence ofwhich he is capable.

　　The importance of environment in determining an individual's intelligence can bedemonstrated by the case history of the identical twins, Peter and Mark. Being identical, thetwins had identical brains at birth, and their growth processes were the same. When the twinswere three months old, their parents died, and they were placed in separate foster(抚养)homes. Peter was raised by parents of low intelligence in an isolated community with pooreducational opportunities. Mark was reared in the home of well-to-do parents who had been tocollege. He was read to as a child, sent to good schools, and given every opportunity to bestimulated intellectually. This environmental difference continued until the twins were in theirlate teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125,twenty-five points higher than the average and fully forty points higher than his identicalbrother. Given equal opportunities, the twins, having identical brains, would have tested atroughly the same level.
