Q: Article: Although we already know a great deal about flu, and although the World Health Organizations is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be.   There are three kinds of flu virus, known as A, B and C. flu C virus is  ly stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies   which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability  is less developed in the flu B virus, which affects only human beings. As flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918&1919, when about half the world's population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence  , the ease with which it can be transmitted and the strength of the opposition it encounters  . Scientists, however, have a reliable general picture of the world situation. Question: Which of the following is NOT mentioned as a factor contributing to the extent to which a virus spreads? Yes or no, is the answer "The immunity the virus can bring about."?
A: Yes


Q: Article: Sunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to _ this. In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp  current to store this electricity, and a lamp whose bulb is a light-emitting diode . The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile-phone charger for seven hours. Then, next day, it can be put outside and charged back up again. The trick is that, to be able to use the electricity, the system's keeper must buy a scratch card--for as little as a dollar--on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company's server will respond automatically with an access code to the unit. Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around $80 worth of scratch cards--which Eight19 expects would take the average family around 18 months--the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10-watt solar cell. In that case, he would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supply steadily and affordably. According to Eight19's figures, this looks like a good deal for customers. The firm believes the average energy-starved Kenyan spends around $10 a month on oil--enough to fuel a couple of smoky lamps--plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half that, before owning it completely. Meanwhile, as the... Question: How much would users pay for the cell and scratch cards before they own a 2.5-watt solar cell? Yes or no, is the answer "Around $90."?
A: No


Q: Article: There was once a farmer who had a fine olive orchard. He was very hardworking, and the farm always prospered under his care. But he knew that his three sons despised the farm work, and were eager to make wealth, through adventure. When the farmer was old, and felt that his time had come to die, he called the three sons to him and said, "My sons, there is a pot of gold hidden in the olive orchard. Dig for it, if you wish it." The sons tried to get him to tell them in what part of the orchard the gold was hidden, but he would tell them nothing more. After the farmer was dead, the sons went to work to find the pot of gold. Since they did not know where the hiding-place was, they agreed to begin in a line, at one end of the orchard, and to dig until one of them should find the money. They dug until they had turned up the soil from one end of the orchard to the other, round the tree-roots and between them. But no pot of gold was to be found. It seemed as if someone must have stolen it, or as if the farmer had been wandering in his wits. The three sons were bitterly disappointed to have all their work for nothing. The next olive season, the olive trees in the orchard bore more fruit than they had ever given. When it was sold, it gave the sons a whole pot of gold. And when they saw how much money had come from the orchard, they suddenly understood what the wise father had meant when he said, "There is gold hidden in the orchard. Dig for it, if you wish it." Question: What would be the best title for the passage? Yes or no, is the answer "No pains, no gains"?
