1. Myra: The number of freeway accidents this year in the state of North Carolina, where the speed limit on free ways was lowered to fifty miles an hour two years ago is clear evidence that speed restrictions, rigorously enforced make drivers more aware of the dangers of going too fast. Lewis: Wrong. A close look at the records shows that the number of freeway accidents has been falling ever since the formation of a new special traffic division, which happened two years before the lowering of the speed limit.

1. Most people who received the questionnaire have replied.

One major obligation of the social psychologist is to provide his own discipline, the other social sciences and interested laymen with conceptual tools that will increase the range and the reliability of their understanding of social phenomena.

2. A study of social psychology should be a part of the curriculum of government officials.

3. The social scientist has an obligation to provide the means by which social phenomena are little understood by those outside the field of social psychology.

4. A good social psychologist is obligated principally by the need to solve interdisciplinary problems.

9. Now problems require new solutions. And new problems arise with new populations and new technologies.

12. Professor Archibald had the task of giving grades i.e.. Ranging from A-D in descending value to his 100 students on the basis of the marks they received in three examinations in which the passing mark was 50%. He is guided to follow the following criteria:
