Read the article and select the best answer. Article: The 115m Christmas Bird Count is officially underway. The count is an annual investigation of local and migratory birds and it's organized by the National Audubon Society. From December 14 to January 5, volunteers will gather in more than 2,000 locations in North, Central and South America to count the birds in their area. Each count takes place in a circle about 24 kilometers wide. The volunteers follow specific routes within the circle and record the number of individual birds and the different species they see there in a single day. The results are sent to the National Audubon Society and later published on Audubon's Christmas Bird Count website. The data collected during the bird count is a key source Of information for ornithologists, scientists who study birds. This information is used to develop conservation programs to protect bird habitats and the environment /n general. Data from the bird count was also used to determine that three species-the Western screech owl, the rusty blackbird and the Newfoundland red crossbill - should be added to Canada's list of species at risk. The annual bird count was created to protest another Christmas tradition at the very beginning .in the United States in the 19th century, people would often hold "side hunts" on Christmas Day. Teams of hunters would compete to see who could kill the most birds or other animals that day. In December 1900, Frank Chapman, an American ornithologist, suggested that instead of hunting birds, people should count them. Twenty-seven people in 25 locations joined in the first Christmas bird count Last year, more than 70,000 volunteers took part. This year, counts are scheduled to take place in 17 countries, ranging from the Arctic to the Antarctic, with most located in Canada and the United States .instead of taking place only on Christmas day, counts are now held on different days for different areas. Question: What can we know about the Christmas Bird Count from the passage? Options: A: It was organized monthly by the National Audubon Society. B: It was launched by Frank Chapman, a Canadian ornithologist. C: Its results can be seen on Audubon's Christmas Bird Count website. D: Only 25 people in 27 locations took part in the first Christmas Bird Count.

Q: Read the article and select the best answer. Article: Did anyone find the names of "Great Britain", "the United Kingdom", "England" and "the British commonwealth" which have the same meaning? Strictly speaking, these names all refer to something different. None of them are exactly the same as any of the others. The British isles refer to the main islands and several thousand small ones as well, which you can see on the map. Great Britain, or Britain, refers to the larger of the two main islands. But the word "Britain" is often used as a short form for the United Kingdom or you call it the UK. Now as for England, it refers simply to the largest of the three countries on the island of Great Britain. The United Kingdom is the name of the state and the official name of the country, which many people popularly refer to England. Finally, the Britain commonwealth is the usual name for what is left of the British Empire . This change shows the weakening of British Empire and the rising of the national liberation movements throughout the world today. Question: We can infer that_. Options: A: The country hasn't an exact name. B: Few people know its real name. C: All the names have exact meaning. D: Generally speaking,the names can all be used to stand for the country.
A: D

*Question*
Read the article and select the best answer. Article: Climatic conditions are delicately adjusted to composition of the Earth's atmosphere. If there were a change in the atmosphere -- for example, in the amounts of atmospheric gases -- the climate would probably change also. A slight increase in water vapor , for example, would increase the heat-keeping capacity of the atmosphere and would lead to a rise in global temperatures. The level of carbon dioxide, CO2, in the atmosphere has an important effect on climatic change. Most of the Earth's incoming energy is short-wavelength radiation , which tends to pass through atmospheric CO2easily. The Earth, however, reradiates much of the received energy as long-wavelength radiation , which CO2absorbs and then goes toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430~C.If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2concentration would lead only to a reduction in global temperatures of 3degC. If, because of an increase in forest fires or volcanic activity, the CO2content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relied on both the warmth and the availability of CO2, would probably increase. As a consequence, plant would use more and more CO2. Eventually CO2levels would decrease and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2would thus be returned to the atmosphere and gradually the temperature would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2present in the atmosphere, with regular... Question: Which of the following questions does the information supplied in this passage try to answer? Options: A: What are the steps in the process that takes place as CO2absorbs long-wavelength radiation? B: How might our understanding of the greenhouse effect be improved if the burning of fossil were decreased? C: What might cause a series of regular increases and decreases in the amount of CO2in the atmosphere? D: Why are there fewer meteorological recording stations in the Southern Hemisphere oceanic zone than atmosphere?
