TEXT C
There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with.
Human brains differ considerably , some being more capable than others. But no matter how good a brain he has
to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the
second factor is what happens to the individual— the sort of environment in which he is brought up. If an
individual is handicapped(不利 ) environmentally, it is likely that his brain will fail to develop and he will never
attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were
placed in separate foster(撫養) homes. Peter was raised by parents of low intelligence in an isolated community
with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated
intellectually. This environmental difference continued until the twins were in their late 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 identical brother. Given equal opportunities, the twins, having identical brains,
would have tested at roughly the same level.
