The result in either case is more primitive behaviour. Hostile feelings are apt to be expressed in an aggressive way.
The same man who will step aside for a stranger at a doorway will, when behind the wheel, risks an accident trying to beat another motorist through an intersection. The importance of emotional factors in automobile accidents is gaining recognition. Doctors and other scientists have concluded that the highway death toll resembles an epidemic and should be investigated as such.
Dr Ross A. McFarland, Associate Professor of Industrial Hygiene at the Harvard University School of Public Health, said that accidents "now constitute a greater threat to the safety of large segments of the population than diseases do."
Accidents are the leading cause of death between the ages of 1 and 35. About one third of all accidental deaths and one seventh of all accidental injuries are caused by motor vehicles.
Based on the present rate of vehicle registration, unless the accident rate is cut in half, one of every 10 persons in the country will be killed or injured in a traffic accident in the next 15 years.
Research to find the underlying causes of accidents and to develop ways to detect drivers who are apt to cause them is being conducted at universities and medical centres. Here are some of their findings so far:
A man drives as he lives. If he is often in trouble with collection agencies, the courts, and police, chances are he will have repeated automobile accidents. Accident repeaters usually are egocentric, exhibitionistic, resentful of authority, impulsive, and lacking in social responsibility. As group, they can be classified as borderline psychopathic personalities, according to Dr. McFarland.
The suspicion, however, that accident repeaters could be detected in advance by screening out persons with more hostile impulses is false. A study at the University of Colorado showed that there were just as many overly hostile persons among those who had no accidents as among those with repeated accidents.
Psychologists currently are studying Denver high school pupils to test the validity of this concept. They are making psychological evaluations of the pupils to see whether subsequent driving records will bear out their thesis.
The author believes that, behind the wheel of an automobile, some people act ______.

A. as though they were uncivilized
B. as though they should change their attitudes from hostility to amicability
C. as though their brain fibres needed cutting
D. as though they wanted repress hostile feelings

Scholars and students have always been great travellers. The official case for "academic mobility" is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold.
Mobility of this kind meant also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have no interest in being credited with a startling discovery, or a new technique. It must also have been reassuring to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect.
In the twentieth century, and particularly in the last 20 years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aeroplane, making contact between scholars even in the most distant places immediately feasible, and providing for the very rapid transmission of knowledge.
Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention: there are far more centres of learning, and a far greater number of scholars and students.
In addition one must recognise the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests are precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries.
Frequently these specialisations lie in areas where very rapid developments are taking place, and also where the research needed for developments is extremely costly and takes a long time. It is precisely in these areas that the advantages of collaboration and sharing of expertise appear must evident. Associated with this is the growth of specialist periodicals, which enable scholars to become aware of what is happening in different centres of research and to meet each other in conferences and symposia. From these meetings come the personal relationships which are at the bottom of almost all formalized schemes of cooperation, and provide them with their most satisfactory stimulus.
But as the specialisations have increased in number and narrowed in range, there had been an opposite movement towards interdisciplinary studies. These owe much to the belief that one cannot properly investigate the incredibly complex problems thrown up by the modern world, and by recent advances in our knowledge along the narrow front of a single discipline. This trend has led to a great deal of academic contact between disciplines, and a far greater emphasis on the pooling of specialist knowledge, reflected in the broad subjects chosen in many international conferences.

A. standards are higher at foreign universities
B. their governments encourage them to travel
C. salaries and conditions are better abroad
D. they are eager for new knowledge
