I have read The History and Geography of Human Genes by Luca Cavalli-Sforza but still have some questions. Even though the findings seemingly prove that races are essentially equal on a genetic level, there are differences unexplained. It was Darwin who first(1)the theory of natural selection. His notion was that certain characteristics that help that species(2)are selected over generations by that species. The species does not consciously make the choice for genetic(3)Instead, by surviving longer and being more fruitful, members of that species with the preferred genes gradually become the(4)breed.

Microsoft refuted all those claims in its brief Tuesday, citing numerous cases and court findings over the past 30 years. The company said the case law demonstrates that it did not engage in anticompetitive conduct that contributed significantly to the maintenance of a monopoly. Microsoft also cited the June 1998 Appeals Court ruling that called the union of Windows and Internet Explorer "a genuine integration" The brief comes one week after reports began circulating that the government is preparing to propose the breakup of Microsoft into two or three parts.
It restates many of Microsoft's defenses, claiming that the integration of Web browsing software into Windows benefited millions of consumers and that the software vendor did not prevent users from obtaining Netscape Navigator. Jackson's findings of fact expressly found that "many—if not most—consumers can be said to benefit from Microsoft's provisions of Web browsing functionality with its Windows operating system at no additional charge," the document says. The brief further states that the findings of fact did not say that Microsoft acted with a specific intent to obtain monopoly power in the market for Web browsers. "The Court instead found that Microsoft attempted to increase Internet Explorer's usage share to such a level as would prevent Netscape Navigator… from becoming the 'standard' Web browsing software," the Microsoft brief said.
While the government argues that Microsoft's actions may have made it more difficult for Netscape to use certain channels of distribution, Microsoft's filing cites numerous cases that demonstrate that its actions were within the bounds of competition defined by the law. Microsoft also rejects the government's claim that its licensing agreements illegally prevent computer manufacturers from modifying the first screen that a user sees when Windows launches, saying the license merely restate rights that Microsoft enjoys under federal copyright law. The two sides in the trial, which began in October 1998, can now submit rebuttals to each other's conclusions of law. Oral arguments are scheduled for February 22, and a ruling is expected in the spring.
What conclusion did the government and 19 states draw on Microsoft's case？
A．Judge Jackson in his findings of fact issued November 5, 1999 said Microsoft "enjoys a monopoly" in the personal computer market.
B．Microsoft engaged in illegal "monopoly maintenance" to protect and extend Windows dominance and then tried to monopolize the Internet browser market.
C．The antitrust law should be applied to Jackson's findings of fact on Microsoft.
D．All of the above.
But first, the essence: Is there something about the brain cells work to explain the effect？ In 1978 the neuroscientist Vernon Mountcastle devised a model of the neural structure of the brain's gray matter. Looking like a thick band of colorful bead work, it represents the firing patterns of groups of neurons. Building on Mounteastle, Shaw and his team constructed a model of their own. On a lark, Xiaodan Leng, who was Shaw's colleague at the time, used a synthesizer to translate these patterns into music. What came out of the speakers wasn't exactly toe-tapping, but it was music. Shaw and Leng inferred that music and brain-wave activity are built on the same sort of patterns.
"Gordon is a contrarian in his thinking," says his longtime friend, Nobel Prize-winning Stanford physicist Martin Peri. "That's important. In new areas of science, such as brain research, nobody knows how to do it."
What do neuroscientists and psychologists think of Shaw's findings？' They haven't condemned it, but neither have they confirmed it. Maybe you have to take them with a grain of salt, but the experiments by Shaw and his colleagues are intriguing. In March a team led by Shaw announced that young children who had listened to the Mozart sonata and studied the piano over a period of months improved their scores by 27% on a test of ratios and proportions. The control group against which they were measured received compatible enrichment courses--minus the music. The Mozart-trained kids are now doing math three grade levels ahead of their peers, Shaw claims.
Proof of all this, of course, is necessarily elusive because it can be difficult to do a double- blind experiment of educational techniques. In a double-blind trial of an arthritis drug, neither the study subjects nor the experts evaluating them know which ones got the test treatment and which a dummy pill. How do you keep the participants from knowing it's Mozart on the CD？
In the first paragraph Gordon Shaw's concern is shown over ______.
A．the open hostility by the media towards his findings
B．his strength to keep trying out the "Mozart effect"
C．a widespread misunderstanding of his findings
D．the sharp disagreement about his discovery
