Read the article and select the best answer. Article: Plants, like animals, are subject to diseases of various kinds.It has been estimated that some 30,000 different diseases attack our economic plants; forty are known to attack corn, and about as many attack wheat.The results of unchecked plant disease are all too obvious in countries which have marginal food supplies.The problem will soon be more widespread as the population of the world increases at its frightening rate.Even in countries which are now amply fed by their agricultural products there could soon be the major crops; the resulting famines could kill millions of people, and the resulting hardship on other millions could cause political upheavals disastrous to the order of the world. Some plants have relative immunity to a great many diseases, while others have a susceptibility to them.A blight may be but a local infection easily controlled; on the other hand it can attack particular plants in a whole region or nation.An example is the blight which killed virtually every chestnut tree in North America.Another is the famous potato blight in Ireland in the last century.As a result of that, it was estimated that one million people died of starvation and related ailments. Plant pathologists have made remarkable strides in identifying the pathogens of the various diseases.Bacteria may invade a plant through an infestation of insect parasites carrying the pathogen.A plant can also be inoculated by man.Other diseases might be caused by fungus which attacks the plant in the form of a model or smut or rust.Frequently such a primary infection will weaken the plant so that a secondary infection may result form its lack of tolerance.The symptoms shown may cause an error in diagnosis, so that treatment may be directed toward bacteria which could be the result of a susceptibility caused by a primary virus infection. Question: How many diseases are known to attack wheat? Options: A: Around 30000 B: Forty C: Around 29960 D: Around 40

Read the article and select the best answer. Article: I had made up my mind a long time ago that I would not give a homeless person money, because I could never be sure what that money would be used for. Instead, I decided, I would buy them a sandwich, a cold drink on a hot day, a cup of coffee, whatever I could manage. I was out recently and saw a homeless man outside of a _ . I decided I would buy this man lunch. I bought a sandwich and soda. Just as I was leaving the store, two policemen were approaching the man. Obviously the shop owners had complained of his wandering and the police were there to draw him away from the storefronts. Just as they were about to wake him, I asked one of the officers if it was all right if I just gave the man something before he went. I was not sure why I asked the permission but the policeman said sure and I just left the bag in the man's cart, got in my car and drove off. As I was driving off I remember thinking "I hope people saw that". Then I had to seriously ask myself why I hoped people had seen me give the man a sandwich from Starbucks. Was it because I wanted people to think, "She's such a nice person!"? Why did I hope others had seen me do it? I continued to wonder this all evening. The next morning, it came to me that I wanted people to have witnessed that small act of kindness not so that I would receive credit and praise but so that they might be inspired to do the same and in so doing that others still would witness their acts of kindness. Thus the whole spirit of pity and giving would be lasting. Question: What's the purpose of the passage? Options: A: To show the author is great. B: To encourage people to help others. C: To introduce an experience that changed the author. D: To call on people not to give money to a homeless man.

Ques: Read the article and select the best answer. Article: China's economy, the world's second largest,is showing signs of a rebound that could help it emerge from its worst economic period in l3 years. According to the latest government figures,growth picked up to 7.9%in the final three months of 2012.from 7.4%in the previous quarter.This was driven by state investment in infrastructure(,)projects and efforts to get consumers and companies to spend. Economic stability is seen as vital for China as its new leaders take over "It is obvious that the slowdown in the Chinese economy has _ for the moment."said Fraser Howie,an economist and co-author of Red Capitalism. "But one has to be mindful that any recovery will be limited in its scope,because of the various difficult and unexpected problems that China is facing,"he added. "The new leaders,who take charge in March,will now have to find the right balance between trying to prevent the formation of a property bubble and keeping a healthy growth rate going." That may prove tricky, especially because China's economic growth has slowed significantly from the highs of previous years,and analysts warn that state stimulus measures may decrease. On Friday,the statistical office reported that GDP...the Gross Domestic Product, the main measure of growth.increased by 7.8%in 2012, down from 9.3%in 2011.That was the slowest annual rate of growth since l 999.But it is still way above the weak growth rates experienced by most other major economies last year.Figures for the US,the world's largest economy,and Japan,the third largest.are expected to show growth of about 2%.The l7 members of the euro zone are collectively expected to contract by about 0.4% Question: According to the passage,the new leaders of China have to _ Options: A: create a good and fair economic environment for people B: create more jobs for the graduates from colleges C: increase the speed of economic growth this year D: keep the balance between the property industry and a healthy growth rate

Question: Read the article and select the best answer. Article: On a cool November afternoon in Fleming Island, Florida, Melissa Hawkinson, 41, was driving her five-year-old twins home from school when she saw a sudden splash in Doctors Lake just ahead. What was that? She thought. As she drove up to the scene, she saw a half-submerged car sinking about 30 yards offshore. "It was going down pretty quickly," Hawkinson recalls. She stopped the car near the boat ramp and ran toward the water. Water is going to be cold, she thought. She took off her vest and leather boots, got into the icy water, and swam to the car, where she found Cameron Dorsey, five, trapped into his car as the swirling water rose around him. Hawkinson tried to open the door, but it was locked. So she pushed and pulled hard on the partially open window until she could reach through and unlock the door. She pulled the boy free, swam to shore, and handed him off to onlookers who were only watching them on a dock. The driver, the boy's suicidal father, swam back to land on his own. Afterward, Hawkinson sat on the shore wrapped in a blanket. "For ten or 15 minutes, I couldn't stop shaking," she said. There's nothing visibly extraordinary about Melissa Hawkinson, an energetic stay-at-home mom with brown hair and a sweet smile. Yet something made her different from the dockside onlookers that day. Why do some people act quickly, willing to take a risk for a stranger? What makes them run toward danger rather than away from it? Hawkinson, the Granite Mountain Hotshots (,)---19 of whom lost their life this past summer in Arizona--- every hero who puts his or her life on the line to save another: what makes them brave? Moreover, can bravery be learned, or is it a quality with which you are born? The answer is complex. Bravery taps the mind, brain and heart. It comes from instinct, training and sympathy. Today, neurologists, psychologists and other researchers are studying bravery, trying to uncover the mystery. Question: What is the writer's purpose of writing this passage? Options: A: To set us thinking what makes people brave. B: To call on us to learn from such people as Hawkinson. C: To remind people of risk while saving others. D: To show people bravery can be learned.
