10. Scattered Witnesses. Brown, Jones, and Smith are witnesses to a bank robbery. Brown stated that the criminals fled in a blue "Buick." Jones claimed it was a black "Chrysler," and Smith said it was a "Ford," but not blue. Due to their scatterbrained nature, each of them correctly identified either only the make or only the color of the car. What car did the criminals escape in?
10. The car could not have been blue, because otherwise both Smith's and Jones's statements about the make of the car would have been correct, which is impossible at the same time. Therefore, Brown correctly identified the make of the car, while Jones and Smith correctly identified the color of the car. Consequently, the criminals fled in a black "Buick".
