請依下文回答第 39 題至第 42 題： What makes people smart? It is a question that scientists and philosophers have thought about for centuries, prompting complex calibrations, from head measurements to brain-bending tests. Yet the drive to probe the powers—and the limits—of the human mind has been thwarted by the hard facts of life:the brain was virtually a black box, its inner secrets locked within. Now, scientists are using the latest technology to peer inside. Using machines such as the PET scanner and FMRI machines, which map the changes in the brain’s blood flow, researchers at U.C. Irvine and elsewhere are producing the first images of how gifted, and not-so-gifted, minds go about the task of thinking. In one study, Professor Richard Haier of U.C. Irvine found that brighter people have lower metabolic rate probably because their brains are more efficient. However, when bright people are given harder tasks, their brains work harder than the average person’s. Apparently, brain activity depends, to some extent, on the difficulty level of the task and the level of effort required.
