问题     Read the following text and answer the questions by finding information from the left column that corresponds to each of the marked details given in the right column. There are two extra choices in the right column. Mark your answers on the ANSWER SHEET.(10 points)
    Pigs, dogs and rakes can all be useful in the quest to discover wild truffles, but each has its drawbacks. Pigs like to gobble up the fancy fungi as much as their owners do. Dogs are costly to train. Rakes wreak havoc on the leaf litter that often covers truffle-rich soil, thus damaging the fungi’s environment. Truffles are, nevertheless, successfully being unearthed in areas not traditionally associated with their growth.
    Some of Oregon’s truffles, for example, are fetching $400 a pound(0.45 kg)this season. But that is still less than half the cost of some Italian and French ones.
    Agriculture, though, usually triumphs over hunting and gathering. Truffle orchards—patches of woodland where the fungi have been deliberately introduced—are popping up around the world. Chile, China and New Zealand all have them. But their success is a bit hit and miss, so a way of identifying where truffles will thrive would be welcome.
    That is where Symbios, a company based in Oregon’s northern neighbour, Washington, comes in. Its staff have been working with the Pacific Northwest National Laboratory, in Richland, to develop a way of mapping land that can tell the firm where best to grow black Perigord truffles, generally regarded as France’s most exquisite variety.
    First, the company contacted particularly successful producers of black Perigords in both Europe and Australia. This way, its researchers gathered a set of data about places where these fungi grow well. They then analysed what they found using 11 variables: climate, geology, altitude and eight others that the firm’s president, Jean Buckner, is keeping up her sleeve. That let them work out what constitutes a good site for a truffle orchard.
    Armed with this knowledge, the firm used a range of geographical information systems to create a series of maps of a given area, each showing which places have the right values for one of the ten variables. Lay the maps on top of one another, and the parts where enough appropriate values overlap are the ones in which you should plant truffles.
    The final map ranks sites from one to ten, according to how suitable they look. When the entire group of 11 variables was analysed, 2.2% of Tennessee was awarded the highest possible score. It was the first state Symbios mapped this way, but the company has plans to do the same for California, Oregon and Washington.
    Once the most promising locations have been pinpointed, the firm can find out who owns the land, and begin negotiations. If these prove fruitful, the site will then need to be explored on foot, to determine precisely where the soil’s chemistry and density are best suited for a truffle grove. According to Dr. Buckner, Perigords in general prefer "fluffier" soil.
    Symbios is also looking at ways of using mapping technology to find wild truffles, and into developing an electronic nose that sniffs them out using infra-red sensing, which might provide an alternative to snuffling with pigs and dogs. Its technique could also have wider application, allowing the identification of suitable sites for other crops that are finicky about where they live, such as varieties of the quinoa grain and pinot-noir grapes.

选项
答案C
解析 根据题干California，Oregon and Washington定位到第七段。该段最后一句指出：It(指Tennessee)was the first state Symbios mapped this way，but the company has plans to dothe same for California，Oregon and Washington．“这是Symbios公司通过这种方式绘制地图的第一个州，该公司还打算在加利福尼亚州、俄勒冈州和华盛顿州如法炮制。”与该句表述一致的是[C]项would follow the example of Tennessee“将效仿田纳西州”。
