Better management of soil and water and creative cropping patterns can boost production from rainfall-watered cropland, but the heaviest burden will fall on irrigated land. At present, most farmers irrigate their crops by channeling water down their fields in parallel furrows.One alternative, drip systems, enables farmers to deliver water directly to the plants roots drop by drop, nearly eliminating waste by distributing water at low pressure through a network of perforated plastic tubing installed on or below the surface of the soil, where it then emerges through small holes at a slow but steady pace. Because the plants enjoy an ideal moisture environment, drip irrigation usually offers the added bonus of higher crop yields. Another alternative, sprinklers, can perform almost as well as drip methods when designed properly, but traditional high-pressure irrigation sprinklers spray water high into the air to cover as large a land area as possible, and the more time the water spends in the air, the more of it evaporates before use.Despite the payoffs, the higher costs of these technologies relative to simple flooding methods have been a barrier to their spread, and so has the prevalence of national water policies that discourage rather than foster efficient water use. Many governments have set very low prices for publicly supplied irrigation, leaving farmers with little motivation to invest in ways to conserve water or to improve efficiency and most authorities have also failed to regulate groundwater pumping, even in regions where aquifers are over-tapped. Therefore, farmers might be inclined to conserve their own water supplies if they could profit from selling the surplus, but this practice is often discouraged.Efforts aside from irrigation technologies are also conducive to the reduction of agricultural demand for water; for instance, measurements of climate factors such as temperature and precipitation can be fed into a computer that calculates how much water a typical plant is consuming, and farmers can use this figure to determine, quite accurately, when and how much to irrigate their particular crops throughout the growing season. But the most effective, if unlikely way, to do more with less water is to reconfigure our diets, especially the typical North American diet, which, with its large share of animal products, requires twice as much water as diets common in many Asian and some European countries. Eating lower on the food chain could allow the same volume of water to feed two Americans instead of one, and despite the resultant loss of nutrition, this may be the only recourse for countries serious about reducing their aquifer strain.The primary purpose of the passage is to_.Aexpose the fragile ecological conditions which modern irrigation technologies must ameliorateBargue that new irrigation technologies would ultimately be less efficient than a reconfiguration of the North American dietCargue that efficient water-use is dependent upon a mixture of various modern methodsDprovide an overall view of possible methods for lessening the strain on sources of freshwaterEdescribe the cycle by which aquifers are depleted and then replenished through technology 26.Women s roles in literature nave not evolved nearly as rapidly as women s changing roles in society, and while these changes are reflected somewhat in what is written, female characters in most classic literature written by both men and women seem to adhere to the classic stereotypes. Though writing during an era in which impersonal criticism was virtually the only way for a woman to maintain objectivity, Virginia Woolf protested the notion that authors ought to separate fiction from reality, and her imaginative use of drama and character development to establish her point can be evidenced in her feminist non-fiction, most prominently the battle against patriarchal authority. Owing to its numerous personal references, most critics have claimed that her oeuvre is somehow self-centered or egotistical rather than objective, yet in truth Woolf is not using her personal experiences as a means with which to reflect upon her own self-image, but rather as a way to more vibrantly illustrate her external perceptions.The passage is primarily concerned with_.Adescribing the challenge Woolfs work once presented to the hermetic literary categories of her timeBdescribing the method by which Woolfs work combated the stereotypes of female characters created by her literary predecessorsCproposing the general merits of introducing the personal into non-fiction feminist literatureDranking, by order of permanence, Woolfs most lasting contributions to feminist discourseEexploring the influence Woolf had on subsequent generations of feminist writers and thinkers 27.Given that 8 percent of food crops grows faster on farms using groundwater than the aquifers are replenished, and many large rivers are so heavily diverted that they do not reach the sea for much of the year, researchers believe freshwater sources-underground aquifers and rivers-are stressed.
