单选题{{B}}Passage Three{{/B}} Attacking an increasingly popular Internet business practice, a consumer watchdog group Monday filed a complaint with the Federal Trade Commission, asserting that many online search engines are concealing the impact special fees have on search results by Internet users. Commercial Alert, a 3-year-old group founded by consumer activist Ralph Nader, asked the FTC to investigate whether eight of the Web's largest search engines are violating federal laws against deceptive advertising. The group said that the search engines are abandoning objective formulas to determine the order of their listed results and selling the top spots to the highest bidders without making adequate disclosures to Web surfers. The complaint touches a hot-button issue affecting tens of mil-lions of people who submit search queries each day. With more than 2 billion pages and more than 14 billion hyperlinks on the Web, search requests rank as the second most popular online activity after E-mail. The eight search engines named in Commercial Alerts complaint are: MSN, owned by Microsoft; Netscape, owned by AOL Time Warner; Directhit, owned by Ask Jeeves; HotBot and Lycos, both owned by Term Lycos; AhaVista, owned by CMGI; LookSmart, owned by LookSmart; and iWon, owned by a privately held company operating under the same name. "Portland, Ore-based Commercial Alert could have named more search engines in its complaint, but focused on the biggest sites that are auctioning off spots in their results," said Gary Ruskin, the group's executive director. "Search engines have be-come central in the quest for learning and knowledge in our society. The ability to skew the results in favor of hucksters without telling consumers is a serious problem," Ruskin said. By late Monday afternoon, three of the search engines had responded to The Associated Press' inquiries about the complaint. Two, LookSmart and AltaVista, denied the charges. Microsoft spokesman Matt Pilla said MSN is delivering "compelling search results that people want." The FTC had no comment about the complaint Monday. The complaint takes aim at the new business plans embraced by more search engines as they try to cash in on their pivotal role as Web guides and reverse a steady stream of losses. To boost revenue, search engines in the past year have been accepting payments from businesses interested in receiving a higher ranking in certain categories or ensuring that their sites are reviewed more frequently.

单选题The texture of the soil depends on the relative amounts of different-sized particles that combine to make up the soil. These particles can be as large as stone and gravel or as small as clay. A typical clay soil is composed of approximately 60 percent actual clay, 20 percent silt, and 20 percent sand. The particles in a sandy soil are so fine that it tends to be compact and interferes with the oxygen supply for plant roots. Water has trouble entering this impervious soil, and runoff is very common during rainfalls. A typical light sandy soil is composed of approximately 70 percent sand, 20 percent silt, and 10 percent clay. The particles in a sandy soil are comparatively large, permitting water to enter the soil and to pass through it so quickly that it often carries nutrients with it and dries out very rapidly. The texture of sandy soils is generally very difficult to modify because huge amounts of organic material must be added. A typical loam soil is composed of approximately 40 percent sand, 40 percent silt, and 20 percent clay, making it an ideal garden soil. It is easily worked and retains water and nutrients, which are slowly absorbed by plant roots. A typical adobe soil is a clay soil present in hot, dry areas of the country and is often very hard and cracked. It has all the disadvantages of a heavy clay soil and, being much drier, is more difficult to correct.
