Read the following text and choose the best answer for each question.
The term "IQ" comes from German "Intelligenz-Quotient", coined by the German psychologist William Stern in 1912, who proposed a method of scoring children's intelligence tests. Since the early 20th century, scores on IQ tests have increased in most parts of the world. The phenomenon of rising score performance means that if test-takers are scored by a constant standard scoring rule, IQ test scores have been rising at an average rate of around three IQ points per decade. This phenomenon was named the Flynn effect in the book The Bell Curve after James R. Flynn, the author who did the most to bring this phenomenon to the attention of psychologists.
