input: OPTIONS:
- there is some pesticide left in them
- they are sticky and fizzy
- they have elements that kill pests
- they made the pesticide more effective Now, answer this question: Read the following article and answer the question. Article: Cotton farmers in some Indian villages are busily buying Coca-Cola and Pepsi, believing that the sugar in the fizzy( ) drinks kills pests. Farmers say scientists advised them to mix pesticides with a sugary juice to control pests, and they found the mixture cheaper and more effective than pure chemicals-- although soft drink makers and scientists dismissed the remarks. N. Hamunayya, who has become a famous person in his village in the southeastern state of Andhra Pradesh, said his crop survived an attack of pests which had resisted other pesticides. "We found that all the colas had uniform effect on pests. The pests became dead and fell to the ground, "he said. He said the drinks had all the elements they needed : they were cheaper, sticky, fizzy, and attracted ants, which ate the young of the pests. But Thinupathi Reddy, assistant director of the Regional Agri-Research Station, Guntur, says tests had proved such results wrong. "We conducted some field trials on cotton crop at our research station. There was no obvious productivity or destruction of pests, "he says. Statements from Pepsi and Coca-Cola said there was " no scientific basis" for _ . But their dealers are enjoying increasing sales. Mantan Wall, who sells soft drinks in 17 villages in the region, said sales rose up, thanks to the farmers. " For the 10 days between August and September I had successful business. Instead of just 30 cases( each containing a dozen one-litre bottles) of cola, I started selling almost 200 cases, "he said. " We expected the sales to drop after the news over pesticide residues( ) in the cola drinks. Now I have to keep extra supply for the cotton farmers, "he said. In February, an Indian environment group made a report saying drinks made by Coca-Cola and Pepsi contained pesticides and called for tougher safety standards. The U. S firms strongly rejected the findings of the New Delhi-based Centre for Science and Environment and said their products were safe. Question: The drinks can kill pests because _ . Answer:
A:
output: they made the pesticide more effective

- aspirin can damage train cells if an adult takes too much of it.
- it is easier for people to catch colds when their bodies are stressed.
- some old advice about preventing colds doesn't make any sense.
- the idea that getting cold can cause flu was proved true years ago. Now, answer this question: Read the following article and answer the question. Article: Autumn and winter are cold and flu seasons. Will the old advice about dressing warmly help prevent a cold, or if you get sick, should you follow the old saying, "feed a cold and starve a fever?" And what about that fever? Should you take medicine to reduce your temperature, or is it better to let the body treat the fever itself? Everyone seems to have an answer. But is popular wisdom valuable? Doctor Nelson knows a lot about cold and flu seasons. Nelson says research may be just starting to provide proofs for long-held beliefs. For example, scientists for years were against the idea that getting cold and wet might cause colds or flu. But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses. So maybe it does make sense to wrap up warmly before going outside. And what about feeding a cold and starving a fever? Nelson says if you have a cold and are hungry, you should eat. But a fever, especially a high one, suggests a more serious problem. He says people are usually not hungry when they have a high fever. Eating might even make a person sick. But drinking enough water is important. A fever easily makes the body lose water. Finally, when should you treat a fever? Nelson says a fever should be treated if it stays at 40degC or above for a day or more. A high temperature can damage brain cells. The doctor also believes in treating a fever if it prevents a person from sleeping. Medicine like aspirin, for example, can be used to reduce pain and fever. But aspirin should not be given to children because it can cause serious problems. Question: The passage suggests that _ . Answer:
A:
output: it is easier for people to catch colds when their bodies are stressed.

input: OPTIONS:
- he belongs to the middle class
- he must be a member of the upper class
- he is not likely to be from the upper class
- he may buy an upper class title with the money Now, answer this question: Read the following article and answer the question. Article: British society is considered to be divided into three main groups of classes--the Upper Class, the Middle Class, and the Lower or Working Class. This is known as the Class system and it is important to know something about it if you want to understand British people and society. Most British people grow up with a deep knowledge and understanding of the class system even if they are not very conscious of it. Most people know which class they belong to by the way they speak, their clothes, their interests or even the type of food they eat. Social class is not only about behavior and attitudes. For example, although many upper class people are rich and may own a lot of land, having a lot of money does not make a person upper class. It is also important to come from a particular kind of family, have friends who are considered suitable, have been to a certain type of private school and speak with the right kind of accent. There are people who are poor but who do not think of themselves as working class, because their family background, education, political opinions, etc. are different from those of most working-class people. Many people do not like the class system but it is impossible to pretend that these differences do not exist or that British people do not sometimes form opinions in this way. Question: If an Englishman has much money, _ . Answer:
A:
output:
he is not likely to be from the upper class
