The paragraph below is taken from an article in the San Francisco Chronicle of Tuesday, March 21, 1995. The person quoted in the article is Patrick Portway, executive director of the United States Distance Learning Association in San Ramon, California. Studies of high school students who took German by satellite from teachers at Oklahoma State University found that they consistently outperformed students taking German at their own schools, Portway noted. "The reason is that the instructor is a college German teacher. He uses music videos, German cultural films, all the media that every teacher would love to have. He has $7.5 million TV studio at his fingertips. Before accepting Mr. Portway's reason, what question should you ask him? State the question, and explain why it is relevant.
