The atmosphere of Venus is quite different from ours Measurements taken from the Earth show a high concentration of carbon dioxide in the atmosphere of Venus In fact, carbon dioxide makes up 96 percent of Venus’ atmosphere; nitrogen makes up almost all the rest The Earth’s atmosphere, by
comparison, is mainly nitrogen, with a fair amount of oxygen as well Carbon dioxide makes up less than 0.1 percent of the terrestrial atmosphere
The surface pressure of Venus’ atmosphere is 90 times higher than the pressure of the Earth’s atmosphere, as a result of the large amount of carbon dioxide in the former Throughout Earth’s history, carbon dioxide on Earth has mixed with rain to dissolve rocks; the dissolved rock and carbon dioxide eventually flow into oceans, where they precipitate to form new terrestrial rocks, often with the help of life-forms If this carbon dioxide were released from the Earth’s rocks, along with lower carbon dioxide trapped in seawater, our atmosphere would become as dense and have as high a pressure as that of Venus Venus, slightly closer to the Sun than Earth and thus hotter, had no oceans in which carbon dioxide could dissolve or life to help take up the carbon
Also, Venus has probable lost almost all the water it ever had Since Venus is closer to the Sun than Earth is, its lower atmosphere was hotter even early on The result was that more water vapor went into its upper atmosphere, where solar ultraviolet rays broke in up into hydrogen and oxygen The
hydrogen, a light gas, escaped easily; the oxygen has combined with other gasses or with iron on Venus’ surface
Studies from the Earth show that the clouds on Venus are primarily composed of droplets of sulfuric acid, with water droplets mixed in Sulfuric acid may sound strange as a cloud constituent, but the Earth too has a significant layer of sulfuric acid droplets in its stratosphere However, the water in the lower layers of the Earth’s atmosphere, circulating because of weather, washes the sulfur compounds out
of these layers, whereas Venus has sulfur compounds in the lower layers of its atmosphere in addition to those in its clouds

Trang 3Questions 56 - 65 Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions
Color in textiles is produced by dyeing, by printing, or by painting Until the nineteenth century, all dyes were derived from vegetable or, more rarely, animal or mineral sources Since madder plants could be grown practically everywhere, the roots of some species of the madder plant family were used from the earliest period to produce a whole range of reds Red animal dyes, derived from certain species of scale insects, were also highly value from ancient times through the Middle Ages Blues were obtained from wood, a plant common in Europe and also used in the Near East from the beginning of the Christian era Before the first, nonfading “solid” green was invented in early nineteenth century, greens were
achieved by the overdyeing or overprinting of yellow and blue However, yellow dyes, whether from weld
or some other plant sources such as saffron or turmeric, invariably fade or disappear This accounts for the bluish tinge of what were once bright greens in, for example, women tapestry
The range of natural colors was hugely expanded and, indeed, superseded by the chemical dyes developed during the eighteen hundreds By 1900, a complete range of synthetic colors had been evolved, many of which reached a standard of resistance to fading from exposure to light and to washing that greatly exceeded that of natural dyestuffs Since then, petroleum industry has added many new chemicals, and from these, other types of dyestuffs have been developed Much of the research in dyes was
stimulated by the peculiarities of some of the new synthetic fibers- Acetate rayon, for example, seemed at first to have no affinity for dyes and a new range of dyes had to be developed; nylon and Terylene
presented similar problems
The printing of textiles has involved a number of distinct methods With the exception of printing
patterns directly onto the cloth, whether by block, roller, or screen, all of these are based on dyeing;
that is, immersion of the fabric in a dye bath
