151-155

151. Studies show that in 70 percent of traffic accidents, at least one driver involved is less than 10 miles from home when the accident occurs. This statistic indicates that drivers have a tendency to drive incautiously when they are close to home, probably because familiar surroundings give them a false sense of security. Thus, the places where people feel safest are the places where they are in fact at greatest risk of serious injury.

152. Copper occurs in nature mixed with other minerals and valuable metals in ore, and the proportion of copper in the ore can vary considerably. Until fairly recently, the only way to extract pure copper from ore was by using a process that requires large amounts of electric energy, especially if the proportion of copper in the ore is low. New copper-extracting technologies can use up to 40 percent less electricity than the older method to process the same amount of raw ore, especially when the proportion of copper in the ore is high. Therefore, we can expect the amount of electricity used by the copper-extraction industry to decline significantly.

153. In measuring electrical activity in different parts of the brain, researchers found that people who describe themselves as generally happy have more activity in the left prefrontal lobe of their brains than do other people. Therefore, a medication for stimulating the left prefrontal lobe of the brain would be an effective treatment for clinical depression.

154. The following appeared in a memo from a manager of a car dealership.
"Ten years ago, long-term car leasing became available in our country of Mohilia as an alternative to outright car ownership, and leasing has steadily risen in popularity. For each of the last five years, the number of people leasing new cars has surpassed the number buying new cars. The average age of cars driven in Mohilia is six years; hence, if new car leases again outnumber purchases this year, it is likely that the majority of drivers will be driving leased, not individually owned, cars. Therefore, we should change the focus of our business from selling cars to leasing them."

155. The following appeared in a newsletter about education policy.
'The average annual earnings of high school dropouts are significantly less than the average annual earnings of high school graduates. To address this problem, the state governor has proposed that the state should establish free vocational training programs for high school dropouts. But the availability of such programs would probably encourage some students who would otherwise have graduated to drop out in order to pursue vocational training. Hence the proposed programs would lower, not raise, the average earning potential of young people. Therefore, the state should not establish the vocational training programs but should instead focus on improving academic programs in our high schools.'
