Whatever the final answer to the water crisis may be, it is evidentthat within the High Plains, irrigation water will never again be the abundant, inexpensive resource it was during the agricultural boom years of the mid-twentieth century. (Words 39; Hard)6. Many ecologists now think that the relative long-term stability ofclimax communities comes not from diversity but from the “patchiness”of the environment, an environment that varies from place to place supports more kinds of organisms than an environment that is uniform. (Words 42; Easy)7. These plants are termed opportunists because they rely on their seeds’falling into setting where competing plants have been removed by natural processes, such as along an eroding riverbank, on landslips, or where a tree falls and creates a gap in the forest canopy. (Words 44;Easy)8. Perhaps, like many contemporary peoples, Upper Paleolithic menand women believed that the drawing of a human image could cause death or injury, and if that were indeed their belief, it might explainwhy human figures are rarely depicted in the cave art.

(Words 46; Medium)14. As Patrick Kirch, an American anthropologist, points out, ratherthan being brought by rafting South Americans, sweet potatoes might just have easily been brought back by returning Polynesian navigators who could have reached the west coast of South America.(Words 39; Medium)15. At one time, the animals present in these fossil beds were assignedto various modern animals groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms that arose in the early Cambrian period and disappeared before the end of the period, leaving not descendants in modern animals group.(Words 52; Medium)16.

Since the laws of physics, not some arbitrary decision, havedetermined the general form of applied-art objects, they follow basic patterns, so much so that functional forms can vary only within certain limits. (Words 33; Easy)19. That this device was a necessary structural compromise is clearfrom the fact that the cannonball quickly disappeared when sculptors learned how to strengthen the internal structure of a statue with iron braces (iron being much stronger than bronze). (Words 39; Easy)20. Even though the fine arts in the twentieth century often treatmaterials in new ways, the basic difference in attitude of artists in relation to their materials in the fine arts and the applied arts remainsrelatively constant.

The cinema did not emerge as a form of mass consumption until itstechnology evolved from the initial “peepshow” format to the point where images were projected on a screen in a darkened theater.(Words 34; Easy)22. Although early exhibitors regularly accompanied movies with liveacts, the substance of the movies themselves is mass-produced prerecorded material that can easily be reproduced by theaters with little or no active participation by the exhibitor. (Words 35; Medium)23. With the advent of projection, the viewer’s relationship with theimage was no longer private, as it had been with earlier peepshow devices such as the Kinetoscope and the Mutoscope, which was a similar machine that reproduced motion by means of successive images on individual photographic cards instead of on strips of celluloid.

(Words 46; Hard)31. For example, some early societies ceased to consider certain ritesessential to their well-being and abandoned them, nevertheless, they retained as parts of their oral tradition the myths that had grown up around the rites and admired them for their artistic qualities rather than for their religious usefulness.

In fact, when tapes of begging tree swallows were played at anartificial swallow nest containing an egg, the egg in that “noisy”nest was taken or destroyed by predators before the egg in a nearby quiet nest in 29 of 37 trials. (Words 45; Medium)53. This prediction was supported by data collected in one survey of 24species from an Arizona forest, more evidence that predator pressure favors the evolution of begging calls that are hard to detect and pinpoint. (Words 35; Easy)54. One possibility is that a noisy baby bird provides accurate signals ofits real hunger and good health, making it worthwhile for the listening parent to give it food in a nest where several other offspring are usually available to be fed. (Words 42; Medium)55. When experimentally deprived baby robins are placed in a nest withnormally fed siblings, the hungry nestlings beg more loudly than usual—but so do their better-fed siblings, though not as loudly as the hungrier birds. (Words 36; Medium)56. The answer lies apparently not in the increased energy costs ofexaggerated begging—such energy costs are small relative to the potential gain in calories—but rather in the damage that any successful cheater would do to its siblings, which share genes with one another. (Words 45; Medium)57.

Though it may be difficult to imagine from a later perspective, astrain of critical opinion in the 1920s predicted that sound film would be a technical novelty that would soon fade from sight, just as had many previous attempts, dating well back before the First World War, to link images with recorded sound. (Words 54; Hard)61. To be sure, their evaluation of the technical flaws in 1920s soundexperiments was not so far off the mark, yet they neglected to take into account important new forces in the motion picture field that, ina sense, would not take no for an answer. (Words 46; Hard)62. With financial assets considerably greater than those in the motionpicture industry, and perhaps a wider vision of the relationships among entertainment and communications media, they revitalized research into recording sound for motion pictures. (Words 34; Easy)63. The relations between animal activity and these periods, particularlyfor the daily rhythms, have been of such interest and importance thata huge amount of work has been done on them and the specialresearch field of chronobiology has emerged. (Words 40; Medium)64. Normally, the constantly changing levels of an animal's activity—sleeping, feeding, moving, reproducing, metabolizing, andproducing enzymes and hormones, for example—are wellcoordinated with environmental rhythms, but the key question iswhether the animal's schedule is driven by external cues, such assunrise or sunset, or is instead dependent somehow on internaltimers that themselves generate the observed biological rhythms.(Words 61; Easy)65. The disorienting effects of this mismatch between external timecues and internal schedules may persist, like our jet lag, for several days or weeks until certain cues such as the daylight/darkness cycle reset the organism's clock to synchronize with the daily rhythm ofthe new environment. (Words 46; Hard)66. Therefore, when observational assessment is used as a technique forstudying infant perceptual abilities, care must be taken not toovergeneralize from the data or to rely on one or two studies asconclusive evidence of a particular perceptual ability of the infant.(Words 43; Medium)67. The first is the habituation-dishabituation technique, in which asingle stimulus is presented repeatedly to the infant until there is ameasurable decline (habituation) in whatever attending behavior is being observed. (Words 31; Medium)68. The second technique relies on evoked potentials, which areelectrical brain responses that may be related to a particular stimulus because of where they originate.

To understand the ancient Mayan people who lived in the area thatis today southern Mexico and Central America and the ecologicaldifficulties they faced, one must first consider their environment,which we think of as “jungle" or 'tropical rainforest”. (Words 41;Easy)71. While that made things hard for ancient Maya living in the south, ithas also made things hard for modem archaeologists who havedifficulty understanding why ancient droughts caused biggerproblems in the wet south than in the dry north. (Words 40; Easy)72. The likely explanation is that an area of underground freshwaterunderlies the Yucatan Peninsula, but surface elevation increases from north to south, so that as one moves south the land surface liesincreasingly higher above the water table. (Words 38; Medium)73.

(Words 49; Medium)74. It is the use of horses for transportation and warfare that explainswhy Inner Eurasian pastoralism proved the most mobile and themost militaristic of all major forms of pastoralism. (Words 30; Easy)75. The remarkable mobility and range of pastoral societies explain, inpart, why so many linguists have argued that the Indo-Europeanlanguages began their astonishing expansionist career not amongfarmers in Anatolia (present-day Turkey), but among earlypastoralists from Inner Eurasia. (Words 40; Easy)76. Such theories imply that the Indo-European languages evolved notin Neolithic (10,000 to 3,000 B.C.) Anatolia, but among the foraging communities of the cultures in the region of the Don and Dnieperrivers, which took up stock breeding and began to exploit theneighboring steppes. (Words 45; Easy)77. Inequalities of wealth and rank certainly exist, and have probablyexisted in most pastoralist societies, but except in periods of military conquest, they are normally too slight to generate the stable,hereditary hierarchies that are usually implied by the use of the term class. (Words 44; Medium)78. Inequalities of gender have also existed in pastoralist societies, butthey seem to have been softened by the absence of steep hierarchies of wealth in most communities, and also by the requirement thatwomen acquire most of the skills of men, including, often, theirmilitary skills. (Words 46; Medium)79. In a countercurrent exchange system, the blood vessels carryingcooled blood from the flippers run close enough to the blood vessels carrying warm blood from the body to pick up some heat from thewarmer blood vessels. (Words 37; Medium)80. American paleontologists David Raup and John Sepkoski, who havestudied extinction rates in a number of fossil groups, suggest thatepisodes of increased extinction have recurred periodically,approximately every 26 million years since the mid-Cretaceousperiod. (Words 36; Easy)81. The possibility that mass extinctions may recur periodically hasgiven rise to such hypotheses as that of a companion star with along-period orbit deflecting other bodies from their normal orbits, making some of them fall to Earth as meteors and causingwidespread devastation upon impact. (Words 46; Hard)82. A search of sedimentary deposits that span the boundary betweenthe Cretaceous and Tertiary periods shows that there is a dramatic increase in the abundance of iridium briefly and precisely at thisboundary. (Words 33; Easy)83. When the ice is thick enough, usually over 30 meters, the weight ofthe snow and firn will cause the ice crystals toward the bottom tobecome plastic and to flow outward or downward from the area of snow accumulation. (Words 40; Easy)84. For a glacier to grow or maintain its mass there must be sufficientsnowfall to match or exceed the annual loss through melting,evaporation, and calving, which occurs when the glacier loses solid chunks as icebergs to the sea or to large lakes. (Words 43; Medium)85. Glaciers move slowly across the land with tremendous energy,carving into even the hardest rock formations and thereby reshaping the landscape as they engulf, push, drag, and finally deposit rockdebris in places far from its original location. (Words 38; Easy)86. This has been so since ancient times, partly due to the geology ofthe area, which is mostly limestone and sandstone, with few deposits of metallic ore and other useful materials. (Words 31; Easy)87. In these shops differences of rank were blurred as artisans andmasters labored side by side in the same modest establishment, were usually members of the same guild and religious sect, lived in thesame neighborhoods, and often had assumed (or real) kinshiprelationships. (Words 44; Medium)88. In the multiplicity of small-scale local egalitarian orquasi-egalitarian organizations for fellowship, worship, andproduction that flourished in this laissez-faire environment,individuals could interact with one another within a community ofharmony and ideological equality, following their own popularlyelected leaders and governing themselves by shared consensus while minimizing distinctions of wealth and power. (Words 54; Hard)89. As among tribespeople, personal relationships and a carefulweighing of character have always been crucial in a mercantileeconomy with little regulation, where one's word is one's bond and where informal ties of trust cement together an international tradenetwork. (Words 40; Medium)90. Nor have merchants and artisans ever had much tolerance foraristocratic professions of moral superiority, favoring instead anegalitarian ethic of the open market, where steady hard work, theloyalty of one's fellows, and entrepreneurial skill make all thedifference. (Words 40; Hard)91. The central state, though often very rich and very populous, wasintrinsically fragile, since the development of new international trade routes could undermine the monetary base and erode state power, as occurred when European seafarers circumvented Middle Easternmerchants after Vasco da Gama's voyage around Africa in the latefifteenth-century opened up a southern route. (Words 55; Medium)92. When the elements known at the time were ordered by increasingatomic mass, it was found that successive elements belonged todifferent chemical groups and that the order of the groups in thissequence was fixed and repeated itself at regular intervals. (Words 42; Hard)93. Ramsay then studied a gas that was present in natural gas depositsand discovered that it was helium, an element whose presence in the Sun had been noted earlier in the spectrum of sunlight but that had not previously been known on Earth. (Words 43; Medium)94. It is hypothesized that the primordial cloud of dust and gas fromwhich all the planets are thought to have condensed had acomposition somewhat similar to that of Jupiter. (Words 30; Easy)95. The explanation may be that the terrestrial planets were once muchlarger and richer in these materials but eventually lost them because of these bodies' relative closeness to the Sun, which meant that their temperatures were relatively high. (Words 38; Easy)96. This development, coming as it did when the bottom had fallen outof the European economy, provided an impetus to a long-held desire to secure direct relations with the East by establishing a sea trade.(Words 35; Medium)97. But even high-priced commodities like spices had to be transportedin large bulk in order to justify the expense and trouble of sailingaround the African continent all the way to India and China. (Words 34; Medium)98. In the largest caravels, two main masts held large square sails thatprovided the bulk of the thrust driving the ship forward, while asmaller forward mast held a triangular-shaped sail, called a lateensail, which could be moved into a variety of positions to maneuver the ship.
