I'm taking a test and have to guess the right answer to the question after the article. Article: Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don't take notice, it can have an effect on our hearing. Most teenagers don't think about hearing loss. But if you experience any of the followingsymptoms , you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people's expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears. iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of itsmaximum volume , and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal. Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss. Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it's like working in a loud factory all day, being amaintenance person under a jet airplane or using ajackhammer on a building site. Similarly, iPod music can cause a short time orpermanent hearing damage. A loud iPod can cause aruptured eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to theauditory nerves that connect to the brain. If this happens, hearing loss becomes permanent. Question: This passage is mainly about _ . Options: A: music that teenagers like B: hearing problems caused by the loud world C: ways that teenagers enjoy music D: dangerous modern lifestyles of teenagers.

I'm taking a test and have to guess the right answer to the question after the article. Article: Farmers may not be able to prevent natural disasters, but they can at least try their best to reduce losses. For example, they can plant crops that are more likely to survive extreme weather. In north-central Vietnam, people with small farms do not plant rice between September and December. Seasonal rains might destroy the rice. So instead, they plant lotus seeds on raised beds. The United Nations Food and Agriculture Organization says the lotus seeds _ . Farmers in the Philippines are showing new interest in crops like winged beans, string beans, arrowroot and cassava. The Asian Disaster Preparedness Center says traditional crops like these can survive the fierce storms that often strike the islands. The United Nations says some African farmers grow bambara groundnuts during long dry periods. The seeds of this drought-resistant plant can be boiled for eating or for making flour. In some parts of the world, farmers grow vetiver grass. Researchers in Thailand wrote about vetiver in 2007 in the journal Science Asia. They noted that the grass can absorb and control the spread of harmful waste waters, like those from pig farms. Agricultural expert and author William Rivera says vetiver resists difficult conditions. It reduces damage from heavy rains. And vetiver planted on earthen dams may strengthen them against breaks and flooding. William Rivera also speaks approvingly of alfalfa. Its deep roots can find and take up groundwater. Those roots also help hold the soil against winds. And alfalfa can be a valuable food source for animals. The deep and extensive roots of sunflowers make them another good candidate for resisting extreme conditions. The tall plants have brightly color1ed heads that provide seeds and oil. North Dakota grows more hectares of sunflowers than any other American state. But North Dakota is better known as a top wheat producing state. Hans Kandel works at the North Dakota State University Extension Service in Fargo. He says farmers in some parts of North Dakota plant wheat that is... Question: From this passage we may safely conclude that _ . Options: A: weather conditions are always decisive factors in agriculture B: some crops can help farmers to fight against extreme weather C: agriculture is developing fast in the world D: the species of the world are changing quickly

I'm taking a test and have to guess the right answer to the question after the article. Article: The rise of multinational corporations , global marketing, new communications technologies, and shrinking cultural differences have led to an unparalleled increase in global public relations or PR. Surprisingly, since modern PR was largely an American invention, America's relations is being threatened by PR efforts in other countries. Ten years ago, for example, the world's top five public relations agencies were American-owned. In 1991, only one was. The British in particular are becoming more sophisticated and creative. A recent survey found that more than half of all British companies include PR as part of their corporate planning activities, compared to about one-third of U.S. companies.It may not be long before London replaces New York as the capital of PR. Why is America lagging behind in the global PR race? Firstly, Americans as a whole tend to be fairly provincial and take more of an interest in local affairs. Knowledge of world geography, for example, has never been strong in this country. Secondly, Americans lag behind their European and Asian counterparts in knowing a second language. Less than 5 percent of Burson--Marshall's U.S.employees know two languages. Ogilvy and Mather have about the same percentage. Conversely, some European firms have half or more of their employees fluent in a second language. Finally, people involved in PR abroad tend to keep a closer eye on international affairs. In the financial PR area, for instance, most Americans read the Wall Street Journal. Overseas, their counterparts read the Journal as well as the Financial Times of London and The Economist, publications not often read in this country. Perhaps the PR industry might take a lesson from Ted Turner of CNN (Cable News Network). Turner recently announced that the word "foreign" would no longer be used on CNN news broadcasts. According to Turner, global communications have made the nations of the world so interdependent that there is no longer any such thing as foreign. Question: It could be inferred that the author of the passage is _ . Options: A: an American B: a Briton C: Ted Turner D: an Asian
