MCQ-> Read the given passage carefully and select the best answer to each question out of the four given alternatives.A growing demand for organics, and the near-total reliance by US farmers on genetically modified corn and soybeans, is driving a surge in imports from other nations where crops largely are free of bioengineering. Imports such as corn from Romania and soybeans from India are booming, according to an analysis of US trade data released Wednesday by the Organic Trade Association and Pennsylvania State University. That shows a potential market for US growers willing to avoid the use of artificial chemicals and genetically modified seeds, said Laura Batcha, chief executive officer of the association, which includes Whole Foods Market Inc., Whitewave Foods Co. and Earthbound Farm LLC. The report is "a help-wanted sign" for US farmers, Batcha said. "There are market distortions that are pretty striking." Most of the corn and soybean shipments become feed for chickens and cows so they can be certified organic under US Department of Agriculture guidelines. Organic poultry and dairy operators shun feed made with seeds from Monsanto Co. and other domestic suppliers in favor of foreign products even as the US remains the world’s top grower of corn and soybeans. As a result, imports to the US of Romanian corn rose to $11.6 million in 2014 from $545,000 the year before. Soybean imports from India more than doubled to $73.8 million. Rising consumer demand in what’s been a niche market is creating shortages, pushing companies that supply farms needing organic feed to seek out foreign sources. About 90% of US corn and soy is bioengineered, thus automatically ineligible for the organic label.What is driving a surge in imports from other nations?

MCQ-> "All raw sugar comes to us this way. You see, it is about the color of maple or brown sugar, but it is not nearly so pure, for it has a great deal of dirt mixed with it when we first get it." "Where does it come from?" inquired Bob."Largely from the plantations of Cuba and Porto Rico. Toward the end of the year we also get raw sugar from Java, and by the time this is refined and ready for the market the new crop from the West Indies comes along. In addition to this we get consignments from the Philippine Islands, the Hawaiian Islands, South America, Formosa, and Egypt. I suppose it is quite unnecessary to tell you young men anything of how the cane is grown; of course you know all that.""I don't believe we do, except in a general way," Bob admitted honestly. "I am ashamed to be so green about a thing at which Dad has been working for years. I don't know why I never asked about it before. I guess I never was interested. I simply took it for granted.""That's the way with most of us," was the superintendent's kindly answer. "We accept many things in the world without actually knowing much about them, and it is not until something brings our ignorance before us that we take the pains to focus our attention and learn about them. So do not be ashamed that you do not know about sugar raising; I didn't  when I was your age. Suppose, then, I give you a little idea of what happens before this raw sugar can come to us.""I wish you would," exclaimed both boys in a breath."Probably in your school geographies you have seen pictures of sugar-cane and know that it is a tall perennial not unlike our Indian corn in appearance; it has broad, flat leaves that sometimes measure as many as three feet in length, and often the stalk itself is twenty feet high. This stalk is jointed like a bamboo pole, the joints being about three inches apart near the roots and increasing in distance the higher one gets from the ground.""How do they plant it?" Bob asked."It can be planted from seed, but this method takes much time and patience; the usual way is to plant it from cuttings, or slips. The first growth from these cuttings is called plant cane; after these are taken off the roots send out ratoons or shoots from which the crop of one or two years, and sometimes longer, is taken. If the soil is not rich and moist replanting is more frequently necessary and in places like Louisiana, where there is annual frost, planting must be done each year. When the cane is ripe it is cut and brought from the field to a central sugar mill, where heavy iron rollers crush from it all the juice. This liquid drips through into troughs from which it is carried to evaporators where the water portion of the sap is eliminated and the juice left; you would be surprised if you were to see this liquid. It looks like nothing so much as the soapy, bluish gray dish-water that is left in the pan after the dishes have been washed.""A tempting picture!" Van exclaimed."I know it. Sugar isn't very attractive during its process of preparation," agreed Mr. Hennessey. "The sweet liquid left after the water has been extracted is then poured into vacuum pans to be boiled until the crystals form in it, after which it is put into whirling machines, called centrifugal machines that separate the dry sugar from the syrup with which it is mixed. This syrup is later boiled into molasses. The sugar is then dried and packed in these burlap sacks such as you see here, or in hogsheads, and shipped to refineries to be cleansed and whitened.""Isn't any of the sugar refined in the places where it grows?" queried Bob."Practically none. Large refining plants are too expensive to be erected everywhere; it therefore seems better that they should be built in our large cities, where the shipping facilities are good not only for receiving sugar in its raw state but for distributing it after it has been refined and is ready for sale. Here, too, machinery can more easily be bought and the business handled with less difficulty." Which one of the following is not a essential condition for setting up sugar refining plants?
