all of them terrestrial mammals and herbivores The five most important of these are sheep, goats, pigs, horses, and cattle or oxen Small animals such as ducks, geese, rabbits, dogs, cats, mink, bees, and silkworms have also been domesticated Many of these small animals provided food, clothing, or warmth However, none of them pulled plows or wagons, none carried riders, and none except dogs pulled sleds Furthermore, no small domestic animals have been as important for food as have large domestic animals Early herding societies quickly domesticated all large mammal species that were suitable for domestication There is archeological evidence that these species were domesticated between 10,000 and 4,500 years ago, within the first few thousand years of the origins of farming herding societies after the last Ice Age The continent of Eurasia has been the primary size of large mammal domestication Eurasia is a huge, ecologically diverse landmass, and therefore has a great many large mammal species Having the most species of wild mammals to begin with, and losing the fewest to extinction in the last 40,000 years, Eurasia has generated the most candidates for domestication Domestication involves transforming wild animals into something more useful to humans Truly domesticated animals differ in many ways from their wild ancestors These differences result from two processes: human selection of individual animals that are more useful to humans that other individuals of the same species, and evolutionary responses of animals to the forces of natural selection operating in human environments rather than in wild environments To be domesticated, a wild species must possess several characteristics A candidate for domestication must be primarily a herbivore because it takes less plant biomass to feed a plant eater than it does to feed a carnivore that consumes plant eaters No carnivorous mammal has ever been domesticated for food simply because it would be too costly A candidate must not only weigh an average of over 100 pounds but also grow quickly That eliminates gorillas and elephants, even though they are herbivores Moreover, candidates for domestication must be able to breed successfully in captivity Since almost any sufficiently large mammal species is capable of killing a human, certain qualities disqualify a wild animal for domestication The animal cannot have a disposition that is nasty, dangerous, or unpredictable characteristics that eliminate bears,, African buffaloes, and some species of wild horses The animal cannot be so nervous that it panics around humans Large herbivorous mammal species react to danger from predators or humans in different ways Some species are nervous, fast, and programmed for instant flight when they perceive danger Others are less nervous, seek protection in herds, and not run until necessary Most species of deer and antelope are of the former type, while sheep and goats are of the latter Almost all domesticated large mammals are species whose wild ancestors share three social characteristics: living in a herd, maintaining a dominance hierarchy in the herd, and having herds Trang that occupy overlapping home ranges instead of mutually exclusive territories Humans have taken advantage of those characteristics in keeping domestic animals together with others of their species and in close proximity to other species of domestic animals The word furnished in par.1 is closest in meaning to A demanded B invented C provided D changed According to the passage, what benefit of large domestic animals is not also provided by small animals? A A source of food B A source of clothing C The ability to pull a plow D The ability to be ridden Which of the following can be inferred about large mammal species? A Relatively few species have the necessary characteristics for domestication B More species of large mammals are domesticated as pets than for food C Only a few large terrestrial mammal species are primarily herbivores D All large mammals can be classified into one of five important groups According to the passage, when did early humans domesticate all suitable large mammal species? A After humans had populated every continent B Before the Ice Age caused many animals to become extinct C At the same time they domesticated small animals D Within a few thousand years after farming and herding began According to the passage, what is one reason that domesticated animals differ from their wild ancestors? A Wild animals find food easily, but domesticated animals must work for food B Domesticated animals live near humans, so they forget their wild ancestors C Animals' evolutionary responses in captivity differ from those in the wild D More animals survive in human environments than in wild environments Why does the author mention gorillas and elephants in par 5? A To suggest that some overlooked animals could be domesticated B To illustrate the wide variety among large herbivores C To identify animals intelligent enough to avoid domestication D To give examples of animals that grow too slowly for domestication The word disqualify in par.6 is closest in meaning to A identify B display C reject D punish The word panic in par.6 is closest in meaning to A feels terror B refuses to eat C attacks others D becomes ill What can be inferred from par.6 about deer and antelope? A They run away from humans only if threatened B They not supply meat of a consistent quality C They are as dangerous as certain wild horses D They have not successfully been domesticated 10 All of the following are characteristics favorable to domestication EXCEPT A weighing over 100 pounds B unpredictable behavior C ability to breed in captivity D living in a herd with hierarchy VII Insert ONE

yet allowing a person to feel comfortable when he is tossing and turning in bed There are mattresses filling with different types of materials and sewn with different types of clothes The need to farther improve the quantity of mattresses shows the importance of the bed as a peace of furniture in a home Whether it is reclining, sleep or even have a meal, people seek to buy the most comfortable beds for them A latex foam bed is one such bed Latex is obtained from the rubber tree and it solidifies quickly and becomes rubbery and elastic These rubber particles are suspending by soap in water and the liquid will then whip into foam and poured into a mould Hundreds of heated pins pierced the mould to creating air chambers for natural ventilation The core of this mixture is then rinsed, washed and squeezed until it is damp The dampness is removed with a hot air oven and further frozen to cool it Latex foam mattresses therefore have a spring-like resilience that not only follow the
