Which of the following most logically completes the passage? On the whole, scientists do their most creative work before age forty, a tendency that has been taken to show that aging carries with it a loss of creative capacity. An alternative explanation is that by age forty most scientists have worked in their field for fifteen or more years and that by then they have exhausted the opportunity for creative work in that field. Supporting this explanation is the finding that __________. A. the average age of recipients of scientific research grants is significantly greater than forty B. a disproportionately large number of the scientists who produce highly creative work beyond age forty entered their field at an older age than is common C. many scientists temper their own expectations of what they can achieve in their research work by their belief that their creativity will decline as they age D. scientists who are older than forty tend to find more satisfaction in other activities, such as teaching and mentoring, than they do in pursuing their own research E. there is a similar diminution of creativity with age in nonscientific fields, such as poetry and musical composition 我没明白B答案起什么作用呢...
Two computer companies, Garnet and Renco, each pay Salcor to provide health insurance for their employees. Because early treatment of high cholesterol can prevent strokes that would otherwise occur several years later, Salcor encourages Garnet employees to have their cholesterol levels tested and to obtain early treatment for high cholesterol. Renco employees generally remain with Renco only for a few years, however. Therefore, Salcor lacks any financial incentive to provide similar encouragement to Renco employees. Which of the following, if true, most seriously weakens the argument? A. Early treatment of high cholesterol does not eliminate the possibility of a stroke later in life. B. People often obtain early treatment for high cholesterol on their own. C. Garnet hires a significant number of former employees of Renco. D. Renco and Garnet have approximately the same number of employees. E. Renco employees are not, on average, significantly younger than Garnet employees.
