Read the following article and select the best answer. Article: American officials have sharply reduced their expecmtions for this year's corn and soybean crops.Farmers in the Midwest are struggling with record heat and the worst drought in many years. The United States is the world's largest producer of com and soybeans.Last Friday the Agriculture Department predicted corn production would add up to 10.8 billion bushels this year.That was down 17%from a prediction made just a month ago.And it was down 13%from last year's level.The average yield per hectare could be the lowest in seventeen years. At the sarne time,the government predicted that soybean production would be 12% lower than last year. The price of corn has hit record levels.Corn is a major part of animal feed,so the price of meat,milk and eggs is also expected to climb. The FAO says average food prices worldwide rose 6%in July.The American drought was a big reason. The situation has renewed the fight between food and fuel.About 40%of the nation's corn crop goes into making ethanol .The production process leaves some of that in a form that can be fed to animals.Still,at least one-fourth of the American corn crop is now made into fuel. The United States requires that part of its corn crop be used in the production of biofuels .The use of ethanol has grown as government requirements have increased.But Jose,the head of the FAO called for"an immediate,temporary pause"of that requirement.He said more of the American corn production could then be used as food or to feed animals. The American livestock industry is also urging Congress to stop the law that requires ethanol in gasoline.But corn farmer Alan Bennett says doing that would hurt his town. A 2005 law requires automobile fuel to contain ethanol.The growth of the ethanol industry and competition for corn has been helping parts of rural America that had been reducing for years. Question: Which of the following statements is TRUE? - Ethanol should be added to all gasoline according to the American law. - Forty percent of the nation's com crop is now made into fuel - America requires the use of ethanol be stopped temporarily. - Most American corn has been used as food or to feed animals.
Ethanol should be added to all gasoline according to the American law.

Read the following article and select the best answer. Article: CHICAGO (Reuters) - Smoking not only can wrinkle the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday. The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun. "We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement. "In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report. The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers. Independent judges decided how wrinkled each person's skin was. When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote. Several previous studies have found that cigarette smoking contributes to premature skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light. The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels beneath the skin to constrict , reducing blood supply to the skin. Smoking can also damage the connective tissue that supports both the skin and the internal organs. Question: From the passage smoking results in skin aging mainly because _ . - it will lower blood supply to skin - it can make you feel tired - it can make skin come off - it can make blood run faster
it will lower blood supply to skin

Read the following article and select the best answer. Article: Technology today has stolen away our voices and robbed our children of memories. I've been keeping count of how often people sing around the house these days. The fact is, they don't. My earliest memories are of my mother crooning lullabies in a gentle low voice as she rocked each infant in turn. She said she "didn't have a singing voice," but her low, wavering alto will always mean comfort to me. Every time I have sat through the night with a feverish body or held a pre - schooler through a nightmare, the melodies returned, words appearing and disappearing like fragments of a dream but held together by the hum of love. Today, young mothers are routinely presented with lullaby tapes at the baby shower. When baby cries, the idea goes, they will be able to switch on the high-tech audio system and _ with the voices of strangers in his ears, perfectly on pitch. If I had my way, new parents would learn the songs themselves, throw out their stereos, and give their child the gift of their own sleepy voices through the midnight hours. These days, when we go on a trip, my daughters take along tiny personal stereos and headphones. They are lost in their private worlds, and I can't help wishing that at least here, in the car my girls would be forced to listen to their mother's voice again, sure I'm out-of-tune songs that they might then pass down to another generation. Those sophisticated earphones have robbed them of something I think every kid should carry from childhood car trips into adulthood. I drove away from that party humming, and all the way home the good old songs kept tumbling out. Damm it , I thought, why did I ever stop singing in the car and start turning on the radio ? Why don't I sing anymore while I'm doing the dishes? I'm going to pull those stereo wires right out of the wall when I get home. We're going to sing grace before meals, sing carols around the piano, sing in the shower instead of switching on that waterproof radio that stole away our voices and our souls. Question: What the author wishes to make her girls do is to _ . - help memorize the words while she is singing - take off their well - designed earphones - listen and learn the old songs from her - remember their childhood car trips
listen and learn the old songs from her
