The Most Powerful Force in Space
A black hole is a spot in space that has incredibly powerful gravity. A hole’s gravity is so strong that it pulls everything nearby into it. It can pull stars, planets, and other things. Nothing can escape a black hole. In fact, they are so powerful that even light cannot escape them. Scientists first started talking about black holes in the year 1783. That year, one scientist said that in the universe, there might be places with gravity strong enough to trap light. However, that scientist didn’t use the term “black hole”. The term “black hole” was invented in 1967. Black holes are formed when a star dies. When a star dies, it collapses. When that happens, a huge amount of matter crowds into a very small space. The matter becomes very, very dense. How much matter are we talking about? Imagine a star that is the size of ten suns. Imagine fitting that amount of matter into New York City. That is what a black hole is like. Its gravity is so powerful because it has so much matter. However, not all black holes are huge. Scientists believe that some black holes are the size of atoms. Although these black holes are tiny, they might have the same amount of matter that a mountain has. We can’t see black holes because they don’t have any light. They are completely invisible. Scientists can guess where black holes are by studying nearby stars and planets. If gravity seems to be pulling the stars and planets to one spot, then scientists believe that the spot is a black hole. Some people wonder if a black hole could ever destroy the Earth. We do not need to worry about that. There is no black hole that is close enough to destroy the Earth. The closest black hole is about 7,800 light years away. In addition, the sun is not big enough to create a black hole.
2. How do scientists study black holes?

Putting Cars on Autopilot
Automobile accidents are one of the leading causes of death each year. Accidents can occur due to drunk driving, mechanical problems, carelessness, or a whole assortment of other reasons. In the near future, these problems could be solved by eliminating the person behind the wheel. Driverless cars may soon be turning all vehicle owners into “backseat drivers”. Driverless cars are vehicles that use several technologies to operate without human input. Through GPS, they can find a location on a map and plan the best route to get there. They may also use radar to detect other vehicles and avoid them when necessary. One company involved with developing driverless cars is Google. It’s developing a software called Google Chauffer which powers the vehicles. The technology isn’t cheap though, as Google robotic cars contain about $150,000 worth of equipment. In 2012, Google began testing the cars on the road with a highly-skilled driver in the driver’s seat, and a Google engineer in the passenger seat. In case there are any malfunctions, the human driver can step on the brakes or turn the wheel to take control of the automobile. Other car manufacturers are also working on implementing automated options into their cars. For example, the 2014 Mercedes-S class offers advanced cruise control using radar, lane warnings, and even detects, and warns drivers when they appear tired. Many Americans seem open to the idea, as three states have already passed laws that make it legal for driverless cars to be on the road. Still there will be some stumbling blocks to overcome before the roads are controlled by digital decision-makers. Firstly, companies will need to provide proof that driverless cars were tested a lot and are truly safe. Automobile manufacturers will also have to find a way to bring down costs, as few people would be able to afford the equipment required. Driverless cars could also potentially become targets for computer hackers. If a hacker were somehow able to override the software system, they could cause accidents or malfunctions. There are also economic issues to consider. If driverless cars became successful, millions of truck, bus, and taxi drivers would likely lose their jobs. Despite these issues, all indications suggest that it should be just a matter of time before humans are no longer needed behind the wheel.

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:
There are three valid arguments to support the preservation of endangered species. Aesthetic justification contends that biodiversity contributes to the quality of life because many of the endangered plants and animals are particularly appreciated for their unique physical beauty. The aesthetic role of nature in all its diverse forms is reflected in the art and literature of every culture attaining symbolic status in the spiritual life of many groups. According to the proponents of the aesthetic argument, people need nature in all its diverse and beautiful forms as part of the experience of the world.
Another argument that has been put forward, especially by groups in the medical and pharmacological fields, is that of ecological self-interest. By preserving all species, we retain a balance of nature that is ultimately beneficial to humankind. Recent research on global ecosystems has been cited as evidence that every species contributes important or even essential functions that may be necessary to the survival of our own species. Some advocates of the ecological argument contend that important chemical compounds derived from rare plants may contain the key to a cure for one of the diseases currently threatening human beings. If we do not protect other species, then they cannot protect us.
Apart from human advantage in both the aesthetic and ecological arguments, the proponents of a moral justification contend that all species have the right to exist, a viewpoint stated in the United Nations World Charter for Nature, created in 1982. Furthermore, if humankind views itself as the stewards of all the creatures on Earth, then it is incumbent upon human beings to protect them, and to ensure the continued existence of all species. Moral justification has been extended by a movement called “deep ecology,” the members of which rank the biosphere higher than people because the continuation of life depends on this larger perspective. To carry their argument to its logical conclusion, all choices must be made for the biosphere, not for people.

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions form 31 -35

Tourism will always have an impact on the places visited. Sometimes the impact is good, but often it is negative. For example, if lots of people visit one place, then this can damage the environment. The question is - how can we minimize the problems without preventing people from travelling and visiting places? 

The main aim of ecotourism is to reduce the negative impact that tourism has on the environment and local people. The idea is to encourage tourists to think about what they do when they visit a place. 

It's great to talk about protecting the environment, but how do you actually do this? There are a number of key points. Tourists shouldn't drop litter, they should stay on the paths, they shouldn't interfere with wildlife and they should respect local customs and traditions. 

Some people see ecotourism as a contradiction. They say that any tourism needs infrastructure - roads, airports and hotels.The more tourists that visit a place, the more of these are needed and, by building more of these, you can't avoid damaging the environment. 

But, of course, things aren't so black and white. Living in a place of natural beauty doesn't mean that you shouldn't benefit from things like better roads. As long as the improvements benefit the local people and not just the tourists, and the local communities are consulted on plans and changes, then is there really a problem? 

In 2002 the United Nations celebrated the "International Year of Ecotourism". Over the past twenty years, more and more people have started taking eco-holidays. In countries such as Ecuador, Nepal, Costa Rica and Kenya, ecotourism represents a significant proportion of the tourist industry.

Read the following passage and choose the best answer (A, B, C, D):
Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose and amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person's diet. This translates to about 75- 100 grams of carbohydrates per day. A diet that is deficient in carbohydrates can have an adverse effect on a person's health. When the body lacks a sufficient amount of carbohydrates it must then use its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a buildup of ketones in the body that causes fatigue, lethargy, and bad breath.
