One of the most vivid symbols of global warming is the torrents of melt water that drain from the lakes that form each summer on Greenland’s ice sheet. Recent studies have shown that this water, which flows deep into the ice through natural drainpipes called moulins, allows the ice to slide faster over bedrock toward the ocean. And the faster the ice flows, the faster sea levels rise. But a Dutch study using 17 years of satellite measurements in western Greenland suggests that the movement associated with the meltwater is not as rapid as had been feared. The acceleration appears to be a transient summer phenomenon, the researchers said, with the yearly movement actually dropping slightly in some places. "The positive-feedback ,mechanism between melt rate and ice velocity," says the report, published Friday in the journal Science, "appears to be a seasonal process that may have only a limited effect on the response of the ice sheet to climate warming over the next decades." Greenland is still losing more ice through melting than it gains through snowfall, other measurements show. The study was led by Roderik S. W. van de Wal of the Institute for Marine and Atmospheric Research of the University of Utrecht. He said the overall slowdown might be because of changing plumbing deep inside the ice. The study builds on earlier work also showing a limited overall change in ice flow from the surface melting. The authors and independent experts familiar with the research stressed that the findings did not preclude the possibility that more widespread surface melting could eventually destabilize big areas of Greenland, the world’s second largest ice storehouse. Richard B. Alley, a glaciologist at Pennsylvania State University, said that big lakes were likely to form as areas of melting spread inland, and that this could unlock new ice regions to start sliding more. But Dr. Alley and other experts said the new study showed that it was unlikely that Greenland’s ice had already become destabilized in ways that could cause a surge in sea levels. According to the passage, the Dutch study was NOT ______.

Which of the following is probably NOT a direct result of global warming according to the passage
What we know of prenatal development makes all this attempt made by a mother to mold the character of her unborn child by studying poetry, art, or mathematics during pregnancy seem utterly impossible. How could such extremely complex influences pass from the mother to the child There is no connection between their nervous systems. Even the blood vessels of mother and child do not join directly. An emotional shock to the mother will affect her child, because it changes the activity of her glands and so the chemistry of her blood. Any chemical change in the mother’s blood will affect the child for better or worse. But we can not see how a looking for mathematics or poetic genius can be dissolved in blood and produce a similar liking or genius in the child. In our discussion of instincts we saw that there was reason to believe that whatever we inherit must be of some very simple sort rather than any complicated or very definite kind of behavior. It is certain that no one inherits a knowledge of mathematics. It may be, however, that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children become deeply interested in mathematics, they will probably make a success of that study. As for musical ability, it may be that what is inherited is an especially sensitive ear, a peculiar structure of the hands or the vocal organs connections between nerves and muscles that make it comparatively easy to learn the movements a musician must execute, and particularly vigorous emotions. If these factors are all organized around music, the child may become a musician. The same factors, in other circumstance might be organized about some other center of interest. The rich emotional equipment might find expression in poetry. The capable fingers might develop skill in surgery. It is not the knowledge of music that is inherited, then nor even the love of it, but a certain bodily structure that makes it comparatively easy to acquire musical knowledge and skill. Whether that ability shall be directed toward music or some other undertaking may be decided entirely by forces in the environment in which a child grows up. Which of the following is the most important to make a child become a musician
