根据以下材料，回答题Racial Prejudice
In some countries where racial prejudice is acute, violence has been taken for granted as a means of solving differences, and this is not even questioned. There are countries 51_________ the white man imposes his rule by brute (粗暴的) force, there are countries where the black man protests by 52_________ fire to cities and by looting and pillaging (抢劫). Important people on both sides, who would appear to be reasonable men, get up and calmly argue in 53_________ of violence as if it were a legitimate (合法的) solution,54_________ any other. What is really frightening, what really 55_________ you with despair, is the realization that when it comes to the crunch( 关键时刻), we have made no actual 56_________ at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded 57_________ of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that 58_________ never solves a problem but makes it more acute. The sheer horror, the blood and the suffering. 59_________ nothing.
No solution ever comes to 60_________ the morning after when we dismally ( 阴郁地) contemplate the smoking ruins and wonder what hit us.
The truly reasonable men who 61_________ where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persecuted 62_________ their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into 63_________ acts were put to good use, if our efforts were directed at 64_________ up the slums and ghettos ( 贫民窟), improving living-standards and providing education and employment for all,we would not have gone a long way to 65_________ at a solution.
