Ques: Read the following article and select the best answer. Article: People and the sources of air pollution are found in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes from cars. Statistics show that 93 percent of all auto trips are within cities. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country. On the average, we throw away more trash and garbage than the year before. The burning of garbage contributes to air pollution. Many major industries are also responsible for the dirty air in the around cities. The fumes from iron, steel, chemical, and petroleum production add particles to the air. The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy for traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode. In some of the larger cities, these fumes endanger the live of human beings by contributing to lung diseases and causing early death. Question: Why is air pollution more grave in the city than in the country? - Because there are larger populations in cities. - Because the air in the city is dirty. - Because there are more cars in the city. - Because there are much more gas fumes from cars and burning of coal and oil for energy in the city than in the country.
Ans: Because there are much more gas fumes from cars and burning of coal and oil for energy in the city than in the country.

Ques: Read the following article and select the best answer. Article: Not everyone goes to university after high school graduation. Some work, others join the army and an increasing number worldwide are taking a "gap year" to travel or do community service in their own countries or abroad. They are studying sharks off the Australian coast, building schools in Mexico and learning Spanish or Italian. The concept of a gap year may not be new, but the recent surge of interest certainly is. Some students are putting off admissions. Others, who don't get into the college of their choice, are taking a year to explore new frontiers before reapplying. Students are choosing to take a breather; they are thinking. They are not sure what they are going to do. They are going and exploring some of their interests. They are getting experience they can take to the school they finally go to. It is an idea actively encouraged by colleges. Princeton University has just launched a "bridge year" program that will send 10 percent of its incoming class to do volunteer work abroad, starting in 2009. And the Harvard has spent the last 30 years urging incoming students to take a gap year. "Many speak of their year away as a 'life-changing' experience or a 'turning point'" says Harvard admissions director Marlin Lewis. "Many come to college with new opinions about their academic plans, their extracurricular interests and the career possibilities they observed in their year away." Question: A student won't _ in a gap year. - travel - join the army - do community service - learn a foreign language
Ans: join the army

Ques: Read the following article and select the best answer. Article: The rise of the so-called "boomerang generation" is revealed in official figures showing that almost one in five graduates in their late 20s now live with their parents. By contrast, only one in eight university graduates had failed to fly the nest by the same age 20 years ago. It also found that grown-up sons are twice as likely as their sisters to still be living with their parents in their late 20s. With nearly a quarter of men approaching 30 still living at home, the findings are bound to lead to claims of a "generation of mummy's boys". Young professionals in their late 20s or early 30s have been nicknamed the "boomerang generation" because of the trend toward returning to the family home having initially left to study. Recent research has suggested that young people in Britain are twice as likely to choose to live with their parents in their late 20s than their counterparts elsewhere in Europe. Growing housing prices, rising student debts and the effects of recession on the job market have forced a wave of young people to move back into the family home at an age when they would normally be moving out. But commentators warned that the phenomenon may have more to do with young people facing " _ " prospects than simply a desire to save money. While the proportion of those of university or college age moving out from the family home has continued to rise in the last 20 years, among those in their mid and late 20s the trend has been reversed. Overall 1.7 million people aged from 22 to 29 now share a roof with their parents, including more than 760,000 in their late 20s. In 1988, 22.7 per cent of men aged 25 to 29 were still living with their parents but last year the proportion was 24.5 per cent. Question: What is the main idea of the passage? - The economic crisis has shown its effect on the young generation. - More young professionals are returning home to live. - British parents are suffering more loads from their grown-up children. - Britain is suffering more than any other country in Europe.
Ans: More young professionals are returning home to live.

Ques: Read the following article and select the best answer. Article: Even if you're not an astronomy fan, chances are that you can easily recognize certain constellations and stars such as the Big Dipper and the North Star. The North Star is the brightest star in the constellation known as the Little Dipper. It is so-called because of the special position. If you were to stay up all night looking at the stars, you'd slowly see them move around a point in the sky known as the North Celestial Pole. You would notice, however, that one star remains still. This is the North Star, so named for its location almost directly in line with the North Celestial Pole. Due to its position in the sky, at one time sailors used the North Star as a navigational tool. By measuring the angle between the northern horizon and the North Star, a navigator could accurately determine the ship's latitude.[:ZXXK] But latitude, or the imaginary lines stretching across the globe parallel to the equator, was not enough to plot a ship's location. Knowing latitude only allowed navigators to locate themselves on a particular latitude line at a particular distance from the equator. It was only with the invention of a way to accurately measure longitude that precise navigation became possible. Although the North Star is no longer used by navigators, it remains a heavenly symbol of human curiosity and exploration. Question: Which is probably the best title of the passage? - What is a navigational tool? - What can be called the earliest GPS? - What makes the North Star so special? - What is the symbol of human exploration?
Ans:
What makes the North Star so special?
