Read the following passage and answer the question given below. In recent years, teachers of introductory courses in Asian American studies have been facing a dilemma nonexistent a few decades ago, when hardly any texts in that field were available. Today, excellent anthologies and other introductory texts exist, and books on individual Asian American nationality groups and on general issues important for Asian Americans are published almost weekly. Even professors who are experts in the field find it difficult to decide which of these to assign to students; non-experts who teach in related areas and are looking for writings for and by Asian American to include in survey courses are in an even worse position. A complicating factor has been the continuing lack of specialized one-volume reference works on Asian Americans, such as biographical dictionaries or desktop encyclopedias. The author of the passage is primarily concerned with doing which of the following? (a) Recommending a methodology (b) Describing a course of study (c) discussing a problem (d) responding to a criticism
