Intelligence: the ability to respond adaptively to new situations, to reason, to think abstractly, to solve problems, and to comprehend complex ideas. How well can you do all these things? Test yourself and find out! Challenge your mind andif you keep working at ityou'll find your brain becoming sharper, faster, and more capable of recognizing and solving incredibly complicated questions and thoughts.

To solve them, apply your mind to each set of diagrams and try to discern recurring logical patterns and sequences. How well would you do on this? Which of the five boxes to the left has most in common with the box above? Give your verbal dexterity a workout with a second group of questions. Find the missing letters to make synonyms; define words; pick the "odd word out"; and choose two words that are the closest in meaningand ones that are opposites. In the following, locate the one that isn't an anagram of a color shade: A) cap trio; B) microns; C) Cartels; D) Pertain; and E) Magnate. The final section, a "Salute to the Masters," presents puzzles dedicated to five geniuses of the 20th Century: Thomas Alva Edison, the great inventor; scientist Albert Einstein; literary genius Mark Twain; Isaac Asimov, blessed with talent in both writing and science; and Sam Loyd, an innovator who devised and compiled some of the world's most creative puzzles. 64 pages, 77 b/w illus., 8 X 10.
