The author suggests that which of the following is adisadvantage that results from the location of asnake39。s political vision.Line 6 In terrestrial environments, gravity placesspecial demands on the cardiovascular systems ofanimals. Gravitational pressure can cause blood topool in the lower regions of the body, making it(5) difficult to circulate blood to critical organs such asthe brain. Terrestrial snakes, in particular, exhibitadaptations that aid in circulating blood against theforce of gravity.The problem confronting terrestrial snakes is best(10) illustrated by what happens to sea snakes whenremoved from their supportive medium. Because thevertical pressure gradients within the blood vesselsare counteracted by similar pressure gradients in thesurrounding water, the distribution of blood(15) throughout the body of sea snakes remains aboutthe same regardless of their orientation in space,provided they remain in the ocean. When removedfrom the water and tilted at various angles with thehead up, however, blood pressure at their midpoint(20) drops significantly, and at brain level falls to zero.That many terrestrial snakes in similar spatialorientations do not experience this kind of circulatoryfailure suggests that certain adaptations enable themto regulate blood pressure more effectively in those(25) orientations.One such adaptation is the closer proximity of theterrestrial snake39。 rather, he gave this consciousness its political expression.Questions 1417 refer to the passage above.14. According to the passage, which of the following contributed to Marcus Garvey39。s characteristics with the characteristics of its four largest moons(E) illustrate the similarity between Jupiter39。s reference to Jupiter39。s four largest moons(C) To explain the significance of the systematic variation in the characteristics of Jupiter39。s and lo39。 Europa is very lightly cratered。s moons are, however, more systematic: many of their properties vary continuously with distance from Jupiter. For example, lo is icefree, Europa has a surface shell of ice, and while Ganymede and Callisto are both icerich, outermostCallisto has more. This positional gradient has geological parallels, lo is extremely geologically active, Europa seems to be active on a more modest scale, and Ganymede has undergone bouts of activity in its geological past. Only Callisto reveals no geological activity. In similar fashion, Callisto39。melekh handles have been found in abundance(40) —more than 4,000 examples so far.The basements of museums are simply notlarge enough to store the artifacts that are likelyto be discovered in the future. There is not enoughmoney even to catalog the finds。 failure to understand the economicimpact of a particular business strategy2. The passage mentions which of the following as apossible consequence of panies39。 Practice QuestionsEach of the reading prehension questions is based on the content of a passage. After reading thepassage answer all questions pertaining to it on the basis of what is stated or implied in the passage.For each question, select the best answer of the choices given.Line 2 Ecoefficiency (measures to minimize environmentalimpact through the reduction or elimination of wastefrom production processes) has bee a goal forpanies worldwide, with many realizing significant(5) cost savings from such innovations. Peter Senge andGoran Carstedt see this development as laudable butsuggest that simply adopting ecoefficiencyinnovations could actually worsen environmentalstresses in the future. Such innovations reduce(10) production waste but do not alter the number ofproducts manufactured nor the waste generatedfrom their use and discard。 realization ofgreater profits through ecoefficiency?(A) The panies may be able to sell a greaternumber of products by lowering prices.(B) The panies may be better able to attractinvestment capital in the global market.(C) The profits may be reinvested to increaseeconomic growth through ecoefficiency.(D) The profits may be used as investment capitalfor industries that are not ecoefficient.(E) The profits may encourage panies to makefurther innovations in reducing productionwaste.3. The passage implies that which of the following is apossible consequence of a pany39。 as a result, they(45) cannot be found again and bee as inaccessibleas if they had never been discovered. Indeed, withthe help of a puter, sold artifacts could be moreaccessible than are the pieces stored in bulgingmuseum basements. Prior to sale, each could be(50) photographed and the list of the purchasers couldbe maintained on the puter. A purchaser couldeven be required to agree to return the piece if itshould bee needed for scientific purposes.It would be unrealistic to suggest that illegal(55) digging would stop if artifacts were sold on theopen market. But the demand for the clandestineproduct would be substantially reduced. Who wouldwant an unmarked pot when another was availablewhose provenance was known, and that was dated(60) stratigraphically by the professional archaeologistwho excavated it?9. The primary purpose of the passage is to propose(A) an alternative to museum display of artifacts(B) a way to curb illegal digging while benefiting thearchaeological profession(C) a way to distinguish artifacts with scientific valuefrom those that have no such value(D) the governmental regulation of archaeologicalsites(E) a new system for cataloging duplicat
