Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42. Earth is richly supplied with different types of living organisms which co-exist in their environments, forming complex, interrelated communities. Living organisms depend on one another for nutrients, shelter, and other benefits. The extinction of one species can set off a chain reaction that affects many other species, particularly if the loss occurs near the bottom of the food chain. For example, the extinction of a particular insect or plant might seem inconsequential. However, there may be fish or small animals that depend on that resource for foodstuffs. The loss can threaten the survival of these creatures and larger predators that prey upon them. Extinction can have a ripple effect that spreads throughout nature. In addition to its biological consequences, extinction poses a moral dilemma for humans, the only species capable of saving the others. The presence of humans on the planet has affected all other life forms, particularly plants and animals. Human lifestyles have proven to be incompatible with the survival of some other species. Purposeful efforts have been made to eliminate animals that prey on people, livestock, crops, or pose any threat to human livelihoods. Some wild animals have been decimated by human desire for meat, hides, fur, or other body parts with commercial value. Likewise, demand for land, water, and other natural resources has left many wild plants and animals with little to no suitable habitat. Humans have also affected nature by introducing non-native species to local areas and producing pollutants having a negative impact on the environment. The combination of these human-related effects and natural obstacles such as disease or low birthrates has proven to be too much for some species to overcome. They have no chance of survival without human help. As a result, societies have difficult choices to make about the amount of effort and money they are willing to spend to save imperiled species. Will people accept limits on their property rights, recreational activities, and means of livelihood to save a plant or an animal? Should saving such popular species as whales and dolphins take priority over saving obscure, annoying, or fearful species? Is it the responsibility of humans to save every kind of life form from disappearing, or is extinction an inevitable part of nature, in which the strong survive and the weak perish? These are some difficult questions that people face as they ponder the fate of other species living on this planet.The word "They" in paragraph 2 refers to ______.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 28 to 34.     Different cultures follow their own special customs when a child's baby teeth fall out. In Korea, for example, they have the custom of throwing lost teeth up on the roof of a house. According to tradition, a magpie will come and take the tooth. Later, the magpie will return with a new tooth for the child. In other Asian countries, such as Japan and Vietnam, children follow a similar tradition of throwing their lost teeth onto the roofs of houses. Birds aren't the only animals thought to take lost teeth. In Mexico and Spain, tradition says a mouse takes a lost tooth and leaves some money. However, in Mongolia, dogs are responsible for taking teeth away. Dogs are highly respected in Mongolian culture and are considered guardian angels of the people. Tradition says that the new tooth will grow good and strong if the baby tooth is fed to a guardian angel. Accordingly, parents in Mongolia will put their child's lost tooth in a piece of meat and feed it to a dog. The idea of giving lost teeth to an angel or fairy is also a tradition in the West. Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are a mystery, although the story probably began in England or Ireland centuries ago. According to tradition, a child puts a lost tooth under his or her pillow before going to bed. In the wee hours, while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. In France, the Tooth Fairy leaves a small gift. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $1 to $5 per tooth, adding up to a lot of money from the Tooth Fairy!The phrase "the wee hours" in paragraph 3 probably refers to the period of time ______.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.A ghostly animal creeps silently through a Florida swamp. It’s a rare type of big cat known as a Florida panther, one of only 80 to 100 such panthers left in the world. Scientists must work to save these remaining panthers from extinction, but their secretive nature is making it difficult. They are attaching a special transmitter to each Florida panther so they can follow their movements, range, and habits. The technology these transmitters use is called satellite tracking.The scientists are dedicated professionals, but they are not pioneers. Their colleagues before them have attached tiny transmitters to many different kinds of wild animals, including birds, fish, and big cats. So the Florida scientists are using their methods. Firstly, they must trap and tranquillize the panther. Then, the transmitter is attached to a harness and strapped to the panther’s body. Each harness is custom designed and manually adjusted for panthers so it fits comfortably. Scientists don’t want the transmitter to interfere with the panther’s natural habits. The point of tracking them is to find out as much as they can about their natural habits.Once the tracking transmitter is in place, the information it records is sent to an orbiting satellite. The satellite can see the transmitter that is attached to the panther, even when it is out of sight of a biologist on the ground. The satellite collects information from the transmitter about thepanther’s exact location. Once the information is received, it is transmitted back to Earth so it can be recorded by the scientists.Scientists can use the information in many different ways. They can follow the panthers on the ground and observe their behavior. Alternatively, they can use the information to determine the panthers’ ranges and to understand their social patterns. They can also track how environmental changes like weather conditions affect their movements and health. All this information can be used to provide ideal conditions for the endangered panthers. It can also be used to protect the panthers from danger.In the end, the panther silently slips away through the trees. Around its shoulders a transmitter is sending signals via satellite to a dedicated biologist. The biologist is using the information the transmitter provides to save the Florida panthers from extinction. With the help of satellite tracking these beautiful cats have a better chance of survival in the modern world.Which of the following could best describe the author’s attitude in the passage?

They can follow the panthers on the ground and observe their behavior. Alternatively, they can use the information to determine the panthers’ ranges and to understand their social patterns. They can also track how environmental changes like weather conditions affect their movements and health. All this information can be used to provide ideal conditions for the endangered panthers. It can also be used to protect the panthers from danger.In the end, the panther silently slips away through the trees. Around its shoulders a transmitter is sending signals via satellite to a dedicated biologist. The biologist is using the information the transmitter provides to save the Florida panthers from extinction. With the help of satellite tracking these beautiful cats have a better chance of survival in the modern world.According to the passage, which of the following about the tracking transmitter is NOT true?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.A ghostly animal creeps silently through a Florida swamp. It’s a rare type of big cat known as a Florida panther, one of only 80 to 100 such panthers left in the world. Scientists must work to save these remaining panthers from extinction, but their secretive nature is making it difficult. They are attaching a special transmitter to each Florida panther so they can follow their movements, range, and habits. The technology these transmitters use is called satellite tracking.The scientists are dedicated professionals, but they are not pioneers. Their colleagues before them have attached tiny transmitters to many different kinds of wild animals, including birds, fish, and big cats. So the Florida scientists are using their methods. Firstly, they must trap and tranquillize the panther. Then, the transmitter is attached to a harness and strapped to the panther’s body. Each harness is custom designed and manually adjusted for panthers so it fits comfortably. Scientists don’t want the transmitter to interfere with the panther’s natural habits. The point of tracking them is to find out as much as they can about their natural habits.Once the tracking transmitter is in place, the information it records is sent to an orbiting satellite. The satellite can see the transmitter that is attached to the panther, even when it is out of sight of a biologist on the ground.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.Marriage nowadays is a choice people make on their own, but this has not always been the case in society. Thousands of years ago, the average lifespan was shorter than it is today. A man usually lived until he was about 40 years old, while women died even sooner because of childbirth. There were many wars and illnesses, and people had to protect themselves by having more children while they were still young. The parents lived through their children.Marriage was not so much a romantic love story but a business transaction, or deal. Most marriages were arranged between parents while their children were still very young. It was the custom that the fathers made the decision on whom their children were going to marry. The mothers had little say in it since they rarely made any decisions outside the household. The fathers would meet to arrange the wedding date and the money given for the bride on her wedding date. The more money and land a girl had, the more chances she had to marry well. Therefore, it was important that her father choose the bridegroom very well. Usually, it was someone who came from a good family or who was rich too. It was very unlikely that people married outside their social class. A few well-off and rich merchants got to marry poorer noblewomen and became King’s business advisors. In a way, poor peasants had an easier choice as it was less important whom they married.The practice of arranged marriage is still common in some countries in the Middle East, such as India or Pakistan. Here, social classes are still strongly divided and very well-kept. Often, however, arranged marriages are a sign that people do not want to let go of the past, which gives them comfort and security in an ever-changing world.The phrase "let go of" in paragraph 3 mostly means                                       .
