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.

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.

What does the passage mainly discuss?

A. Humans and endangered species

B. The importance of living organisms

C. Measures to protect endangered species

D. Causes of animal extinction

Earth is losing wildlife at a faster rate than at any time in history. This is according to the new "Living Planet Report" from the World Wildlife Fund. The report says the global wildlife population shrank by 60 per cent between 1970 and 2014. The WWF warned that: "Earth is losing biodiversity at a rate seen only during mass extinctions." Researchers state that most of the decline in our animal population is because of "exploding human consumption". There are more and more humans on this...

II/ Read the passage and answer the question :
Air pollution is a serious problem in many cities. Motor vehicles, factories and other source create so
much air pollution that it may hang in the air like dirty fog. Air pollution threatens the health of the
people who live in cities. City wastes cause water pollution when they are poured into the waterways.
These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have
difficulties in disposing their garbage. The amount of garbage grows each year, but places to put it are
quickly filling up Citizens, governments, industries, scientists and business people must work
together in different ways to gradually reduce pollution.
True ( T ) or False ( F ) in the space provided
1/ Air pollution is a serious (dangerous) problem in many cities . __________
2/ Air pollution doesn't cause danger to people's health in some cities
3/ Motor vehicles and factories are some of sources of air pollution . ____________
4/ Only factories are the main source of air pollution ._________
5/ Air pollution is the only problem of the environment in this passage .
6/ Some areas are unfit for swimming because of the city wastes .____________
7/ The amount of the garbage in large cities reduces each year ._________
8/ Everyone must cooperate to reduce pollution . ______________

III/ Read the passage and answer the question :
Everyone wants to reduce pollution, but the pollution problem is as complicated as it is serious.
It is complicated because much pollution is caused by things that benefit people. For example,
exhaust from motorbikes causes large percentage of air pollution. But the automobile provides
transportation to millions of people. Factories discharge much of the material that pollutes air
and water, but factories give employment to a large number of people.
Thus, to end or reduce pollution immediately, people would have to stop using many things that
benefit them . Most people do not want to do that, of course. But pollution can be gradually
reduced in many ways. Scientists and engineers can work to find ways to lessen the amount of
pollution that such things as automobiles and factories cause. Governments can pass and enforce
laws that require businesses and individuals to stop or to cut down on certain polluting activities.
True ( T ) or False ( F ) :
1. All people want to reduce pollution_____
2. Pollution problem is neither complicated nor serious_____
3. Pollution is brought about by things that benefit people_____

4. People have to sacrifice what they have to stop or reduce pollution_____
5. The government can't do anything to stop or reduce pollution.______
IV/ Read the passage and answer the questions:
Every day on radio, on TV and in the newspapers, we hear , see, read about many problems in
the world , for example , pollution problems.
Air pollution is the first kind. It mostly comes from fumes released from motorbikes, cars,
airplanes, trains and poisonous gases emitted from factories. Also, waste is dumped anywhere even
in the city where many people are living. The second pollution is sea pollution. Many people earn
their living from fishing the sea, and the fish they catch feed many people. But the sea has become so
polluted from oil spills and factory wastes that the fish are dying. This pollution is not only killing the
fish, but also affecting those people who eat fish.
Seldom do you find a place nowadays that is not polluted. This problem is growing more
difficult every day. We must find a good solution that makes the world a better place to live.
True — False — Not given?
1. Pollution is one of the city's problems_____
2. Exhaust fume comes from vehicles , airplane and factories_____
3. People pollute seas from dynamite fishing____
4. You can find easily a place nowadays that is not polluted_____
