Unlike any other scientific topics,
consciousness—the first-person awareness of the world around—is truly in the eye
of beholder. I know I am conscious. But how do I know that you are Through logical analogy—I am a conscious human being, and therefore you as a human being are also likely to be conscious—I conclude I am probably not the only conscious being in a world of biological puppets. Extend it to other creatures, and uncertainty grows. Is a dog conscious An elm A rock "We don’t have the mythical consciousness meter," said Dr. Chalmers, a professor of philosophy and director of the Center for Consciousness Studies at the University of Arizona. "All we have directly to go on is behavior." So without even an elementary understanding of what consciousness is, the idea of instilling it into a machine—or understandi A. behavior B. logical deduction C. laboratory experiment D. mental testing [单项选择]Unlike other primroses, self-pollinating primroses do not need to rely on insects for pollination. In many years insect pollinators are scarce, and in those years a typical non-self-pollinating primrose produces fewer seeds than does a typical self-pollinating primrose. In other years, seed production is approximately equal. Thus, self-pollinating primroses have the advantage of higher average seed production. Aside from seed production, these self-pollinating primroses are indistinguishable from non-self-pollinating primroses. Nevertheless, self-pollinating primrose plants remain rare among primroses.
Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above A. Insects that collect pollen from primroses do not discriminate between self-pollinating primroses and non-pollinating primroses. B. When insect pollinators are scarce, non-self-pollinating primroses produce larger seeds that are more likely to germinate than are seeds from self-pollinating primroses. C. Self-pollinating primroses that are located in areas with few insects produce no fewer seeds than do self-pollinating primroses that are located in areas with many insects. D. Many primroses are located in areas in which the soil conditions that are optimal for seed germination are not present. E. (E) Self-pollinating primroses can be assisted by insects during pollination but do not require the assistance of insects to be pollinated. [简答题]The Internet, unlike other media such as TV or radio, is inherently (本身固有地) a "two-way" medium. A company user can communicate to the rest of the world with ease. It has created a sense of "global community" that’s found almost nowhere else. People around the world post web sites. exchange e-mail, and participate in on-line chats. Going on-line means not just surfing the Web and reading e-mail. It means getting involved in the whole Net community.
[单项选择]Unlike other examples of ______ verse, Milton’s Lycidas does more than merely mourn the death of Edward King; it also denounces corruption in the Church in which King was ordained.

True, radio-active radon gas—the active ingredient in what the mine’s owners advertise as "the unmedical approach to anthritis"—can cause cancer. (21)But while the radiation level in the old uranium mine is 175 times the federal standard for dwellings, patients spend only a couple of hours a day down there—not enough to be dangerous by itself. The average patient’s age is 72, according to Adrian Howe, chief of the state Occupational Health Bureay; since "the time it takes for lung cancer to develop in an adult is 15 to 30 years, it’s likely that other potential causes of death might occur before lung cancer."
Is it odd that people would seek out a known carcinogen in their quest for relief from arthritis Not really. Arthritis patients are particularly apt to try unproven treatments; one study found that 94 percent of a 我来回答: 提交
