Read the following article and select the best answer. Article: There are stories about two U.S . presidents,Andrew Jackson and Martin Van Buren,which attempt to explain the American English term OK.We don't know if either story is true,but they are both interesting. The first explanation is based on the fact that President Jackson had very little education.In fact,he had difficulty reading and writing.When important papers came to Jackson,he tried to read them and then had his assistants explain what they said.If he approved of a paper, he would write "all correct"on it.The problem was that he didn't know how to spell.So what he really wrote was "ol korekt".After a while,he shortened that term to "OK". The second explanation is based on the place where President Van Buren was born,Kinderhook,New York.Van Buren's friends organized a club to help him become President .They called the club the Old Kinderhook Club,and anyone who supported Van Buren was called"OK". Question: .According to the second story, the term "OK" was first used _ - by Van Buren - in a presidential election - to organize the Old Kinderhook Club - by the members of the "ld Kinderhook Club"

*Question*
Read the following article and select the best answer. Article: Tigers are the largest wild cats in the world. They usually go out to hunt for food when it is dark. When a tiger sees an animal, it moves quickly and then jumps on the animals to kill it. Sometimes it can take the tiger several days to finish eating its food. When the tiger is full, it will cover the dead animal with leaves. Later, when the tiger is hungry again, it comes back to eat some more. Tigers are different from others in the cat family: they like water and often jump into rivers to swim. Some tigers live in very cold places in North Korea, Russia and China. Other tigers live in warmer places--in India and parts of Southeast Asia. But now all tigers are in danger. Some people kill tigers to use their skins for clothes, and their bodies for medicine. There is also less and less land for tigers to live in. ,. Question: Which of the following is NOT true? - Tigers usually go out to look for food at night. - The tiger can kill a big animal very quickly. - The tiger covers the dead animal with leaves if it can't eat it up. - Tigers like to hunt for food in small groups.
**Answer**
Tigers like to hunt for food in small groups.

Read the following article and select the best answer. Article: Worms,antis,and flowers live in soil.Fish,crabs,and seaweeds live in oceans.Birds,insects,and moss live in trees.soil,oceans,and trees are habitatsplaces where animals and plants live .Besides offering food and shelter, habitats allow for growth and reproduction. Humans, however,have destroyed many habitats.We change forests into parking lots. We turn grasslands into neighborhoods.We turn beach land into resorts.We turn 0ceans into chemical dumps.Some plants and animals adapt and survive.Others,however die.The changes are too much,too fast.Sometimes the death rate becomes greater than the birth rate.then the extinction occurs.An example of this happened on Florida's east coast,the habitat of the dusky seaside sparrow.This habitat changed suddenly as land was developed. And the sparrows were not able to adapt. More sparrows died than were born. In 1987 the dusky seaside sparrow became extinct.None exist in the world today. Fortunately,conservation efforts are underway.Many states have set aside land for nature preserves. Here,plants and animals live in their natural habitats.Some states have created man-made habitats .Artificial reefs,for example,have been put in ocean waters. The artificial reefs are habitats for hundreds of fish and other marine life.In 1970 the federal government passed a law to protect habitats.'Ibis~that the efforts of development must be studied.A highway,dam,or power plant may not be built if plants and animals,endangered.We were too late to save the dusky sparrow.Hopefully,however,these new efforts will save other plants and animals. Question: The author explains the effects of habitat destruction by presenting a _ . - real-life example - personal narrative - scientific study - made-un story
**Answer**
real-life example

Read the following article and select the best answer. Article: Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino . The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world. One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe , Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain. The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving. Question: Which of the following is NOT true according to the article? - The computer is used in this research work. - Scientists know when an El Nino appears by means of the computer program. - The scientists published their results of the research work. - Nature is the name of the article written recently by the scientists.
**Answer**
Nature is the name of the article written recently by the scientists.
