Questions 7 to 9 are based on the following reading passage.
National character is not formally considered by social scientists in discussing economic and social development today. They believe that people differ and that these differences should be taken into account 5 somehow, but they have as yet discovered no way to include such variables in their formal models of economic and social development. The difficulty lies in the nature of the data that supposedly define different national characters. Anthropologists and others are on 10 much firmer ground when they attempt to describe the cultural norms for a small homogeneous tribe or village than when they undertake the formidable task of discovering the norms that exist in a complex modern nation-state composed of many disparate groups. The 15 situation is further complicated by the nature of judgments about character; since such judgments are overly dependent on impressions and since, furthermore, impressions are usually stated in qualitative terms, it is impossible to make a reliable comparison between the national characters of two countries.
7. The author's main point in the passage is that national character
○A is too elusive to merit attention by anthropologists and other social scientists.
○B is of greater interest to social scientists today than it has been in the past.
○C is still too difficult to describe with the precision required by many social scientists.
○D has become increasingly irrelevant because of the complexity of modern lift.

□A It is extremely difficult to create models that account for both economic and social development
□B Models of economic and social development would be improved by the inclusion of adequate descriptions of national character.
□C it is important to supplement formal models of economic and social development with qualitative impressions of national character.
9. Which of the following best describes the organization of the passage?
○A A problem is presented and reasons for its existence are supplied.
○B A controversial view is presented and evidence for its validity is supplied.
○C A hypothesis is presented and possible means of verifying it are suggested.
○D A recent development is described and then analyzed.
