million people with I. Q. 's below 90; it is a disturbing thought that these people will never, at any age, read much other than picture books, newspaper headlines, and the simplest of bestsellers, nor will they be able to make intelligent judgments on any complicated, important national or international problem. The intellectuals, of course, are at the other end of the scale; they are people with I. Q. 's of 130 or more, and there are slightly more than five million. From 150 to the top of the scale, there are only 2.1 million people. Careful tests have shown that at least half of these high-I. Q. people are never discovered, do not go to college, and live out their lives in humble, even though usually respected, occupations.

The fact that there are discords between groups along the I. Q. scale is an intricate matter. For one thing, the people at any given level show a curious tendency to disapprove of the mental activities of the people at every other level, above or below: The scorn of the highbrow when he sees a picture book reader is equal to the contempt of the strong, median-I. Q. football player for the genius who wander about, reading poetry when he could be getting a good workout in the gym. It is a curious fact that high intelligence is rarely associated with the excess adrenal activity necessary for success in the bad, competitive world of business; the highbrow comes rather low on the Order of humans. Each group sublimates its hostility, the intellectual often by writing something cutting about the business man, the latter by driving a conspicuously more expensive car than the former can afford.

A complicating factor is the rise of the mass media of communication television, radio, the movies, and magazines with multimillion circulations. Many observers have pointed out that while all of these, to succeed, must be aimed at the median I. Q. , the creative efforts involved have to be made at a much higher level; this situation frequently invalidate the creative intelligence of those who earn their livings through mass communication.

According to :the text, which is the right description about people with I. Q. 's below 90？

A．They can make intelligent judgments on complex issues.

B．What they can read is very simple.

C．They can go to college.

D．They live a humble life.
