1,A major chemical spill occurred five years ago at Baker's Beach, the world's sole nesting ground for Merrick sea turtles,and prevented nearly all the eggs laid that year from hatching. Yet the number of adult female Merricks returing to lay their eggs at Baker's Beach has actually increased somwaht since five years ago. Clearly, environmentalists' prediction that world's Merrick popluation would decline as a result of the spill has proven unfounded.
Which of the following , if true, most seriously undermineds the arguement offered in refutation of the environmentatlist's prediction?
答案: Female Merrick sea turtles begin returning to Baker's Beach to lay their eggs when they are ten years old.
解释下好吗,怎么选出来的?
2, A violin constructed to have imporved sound would sound different from the best-sounding existing violinis. To professional violinists, a violin that sounds different from the best-sounding exiting violins sounds less like a violin and therefore worse than the best-sounding existing violins. Professional violinists are the only accepted judges of the sound quality of violins.
Would be best supported by the those statements?
答案:It is currently impossible to construct a violin that the only accepted judges will evaluate as having improved sound. 解释下吧。谢谢啦 |
