The stories of Sir Nevill Mott, Humboldt and Ernst Mayr show that ______.
A. old researchers can be Nobelists
B. researchers stagnate when they past 60
C. old researchers and scientists can made outstanding achievements
D. great scientists are those who are over 60
Will scientific workers in their 50s and 60s continue to make valuable contributions? The report avoided asking whether aging impairs creativity. If it does, then the growth of our productivity and improvement of our standard of living might be in trouble. There is already a shortage of young Americans in research; in 2003 the NSB expressed concern over the United States' dependence on foreign PhDs.
Scientists, often older ones, have for years questioned how long they can stay productive. G.H. Hardy set the tone in his 1940 classic, A Mathematician's Apology. "Like any other mathematician who has passed sixty," Hardy confessed, "I have no longer the freshness of mind, the energy, or the patience to carry on effectively with my proper job." He continued that "mathematics... is a young man's game."
The age lore of other sciences can be similarly misleading. The Nobel laureate physicist Paul Dirac has suggested, tongue in cheek, that a physicist over 30 was as good as dead, and the physicist-historian Abraham Pals wrote of Einstein after 1925 (when Einstein was 46)that, as far as his work went, he might as well have gone fishing. And yet the sociologist Harriet Zuckerman, in her landmark 1977 book, Scientific Elite ,observed that U.S. Nobelists received their prizes for work done when they were, on average, nearly 39. Sir Nevill Mott won a Nobel Prize in physics for his postretirement research.
Great biologists seem especially hardy. The German naturalist Alexander von Humboldt successfully surveyed harsh, remote areas of the Russian Empire for goldfields after turning 60,and began publishing the 19th century's greatest work of synthesis, Cosmos, at age 76;he had completed 2000 pages by his death at 89,in 1859. More recently, Harvard University's Ernst Mayr was still writing papers at 100.
Why, then, do certain researchers stagnate while others flourish? Some might be internalizing what Zuckerman called the "mythology" of aging in science. But another factor is that any education has built-in limits. Even Einstein may have been bumping against them. Scientists over 40 face a choice: continue using the endowments that have served them well but are challenged by a new generation, or turn to new subjects.

B. average age of the science and engineering workforce in coming decades will be higher
C. for old scientific workers, aging has impaired their creativity
D. the young Americans in research has outnumbered retirees
Why did students voice less skepticism about tuition hikes?
A. Because they had cognitive tension as their classmates did.
Because they shared their classmates' opinion.
C. Because they were convinced by the investigator.
