E. Free-time activities rarely teach children skills or information that they can use in their academic work. Answer: ------------------------------------------------------------------------------------------------------- Q30 For many revisionist historians, Christopher Columbus has come to Personify devastation and enslavement in the name of progress that Has decimated native peoples of the Western Hemisphere. A. devastation and enslavement in the name of progress that has decimated native peoples of the Western Hemisphere B. devastation and enslavement in the name of progress by which native peoples of the Western Hemisphere have been decimated C. devastating and enslaving in the name of progress those native peoples of the Western Hemisphere that have been decimated D. devastating and enslaving those native peoples of the Western hemisphere which in the name of progress are decimated. E. the devastation and enslavement in the name of progress that have decimated the native peoples of the Western Hemisphere. Answer: ------------------------------------------------------------------------------------------------------- Q31 Which of the following most logically completes the argument?? When people engage in activities that help others ,their brain releases endorphins, the brain’s natural opiates, which induce in people a feeling of well-being. It has been suggested that regular release of endorphins increases people’s longevity. And a statistic on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer. How- ever, that statistic would be what we would expect even if volunteering does not boost longevity, because . A. in the communities studied, women were much more likely to do regular volunteer work than men were, and women tend to live longer than men do. B. the number of young adults who do regular volunteer work is on the increase C. the feelings of well-being induced by endorphins can, at least for a time, mask the symptoms of various conditions and diseases, provided the symptoms are mild.

Answer: ------------------------------------------------------------------------------------------------------- Q32 to 35 In 1975 Chinese survey teams remeasured Mount Everest, the highest of the Himalayan mountains. Like the Line British in 1852, they used the age-old (5) technique of “carrying in” sea level: surveyors marched inland from the coast for thousands of miles, stopping at increments of as little as a few feet to measure their elevation, and mark- (10) ing each increment with two poles. To measure the difference in elevation between poles, surveyors used an optical level—a telescope on a level base—placed halfway between the (15) poles. They sighted each pole, read- ing off measurements that were then used to calculate the change in eleva- tion over each increment. In sight of the peaks the used theodolites— (20) telescopes for measuring vertical and horizontal angles—to determine the elevation of the summit. The Chinese, however, made efforts to correct for the errors that (25) had plagued the British. One source of error is refraction, the bending of light beams as they pass through air layers of different temperature and pressure. Because light traveling.
