　　Passage 2

　　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 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.

　　Theimportanceofenvironmentindetermininganindividual'sintelligencecanbe

　　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 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 LQ. 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.
