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(抚养) 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.

In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences, that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence – as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that violence never solves a problem but makes it more acute. The sheer horror, the bloodshed, the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us. The truly reasonable men who know where the solutions lie are finding it harder and herder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law. Before we can even begin to contemplate peaceful co-existence between the races, we must appreciate each other's problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchanging information. "Talk, talk, talk," the advocates of violence say, "all you ever do is talk, and we are none the wiser." It's rather like the story of the famous barrister who painstakingly explained his case to the judge. After listening to a lengthy argument the judge complained that after all this talk, he was none the wiser. "Possible, my lord," the barrister replied, "none the wiser, but surely far better informed." Knowledge is the necessary prerequisite to wisdom: the knowledge that violence creates the evils it pretends to solve.
