Read the following passage and choose the best answer to each of the following questions from 31 to 40.

1. Ocean conservation is the act of protecting and preserving the ecosystems in the world's oceans and seas. Various marine life, including fish, mammals, reptiles, plants, and other sea creatures, rely on ecosystems like coral reefs, mangroves, and the deep sea for survival.

2. The oceans play a vital role in regulating the Earth's climate. [I] Without the oceans' ability to balance the planet's temperature, much of the Earth would be uninhabitable. [II] According to the National 2. Oceanic and Atmospheric Administration (NOAA), ocean currents work like a “large conveyor belt.” [III] This circulation helps drive climate patterns worldwide. [IV] Since oceans cover more than 70% of the Earth's surface, they absorb most of the sun's energy. As the water heats up, it evaporates, which increases humidity and temperature. This process forms rain, which is carried by the wind across the planet.

3. An important job the ocean does is carbon sequestration. Phytoplankton, small marine algae, absorb carbon dioxide from the air and convert it into sugar through photosynthesis. Sea creatures like shrimp, snails, and jellyfish eat these plankton. When these creatures die, their bodies sink to the ocean floor. As they decompose, the carbon remains stored in the deep ocean for millions of years, preventing it from entering the atmosphere and contributing to global warming.

4. The ocean is home to a large percentage of life on Earth, with between 50% and 80% of all species living in the sea. Scientists estimate that between 220,000 and 250,000 species exist in the ocean, and many more remain undiscovered. The ocean's biodiversity is essential for human survival, offering clean air, fresh water, and protection from storms. However, this biodiversity is at risk, with many species threatened with extinction.

Which of the following can be inferred from the passage?

Read the following passage and choose the best answer to each of the following questions from 31 to 40.

1. [I] Waste management is a major issue for cities worldwide, and European cities are leading the way with innovative solutions. [II] One such solution is Waste-to-Energy (WtE), which has become increasingly popular. [III] It reduces the amount of waste sent to landfills while generating clean energy, supporting sustainability, and promoting a circular economy. [IV]

2. The European Union (EU) has set an ambitious goal to reduce landfill use to less than 10% of municipal waste by 2035. To meet this target, solutions like WtE are encouraged. Landfilling is considered the least desirable option in the EU's waste management hierarchy. By diverting waste to WtE, pollution in soil and groundwater is reduced, and harmful emissions in the air and water are minimized. EU regulations ensure that WtE plants operate under strict emission limits, protecting public health and the environment.

3. In addition to reducing waste sent to landfills, WtE also helps lower greenhouse gas emissions by replacing fossil fuels. It also reduces emissions from the burning process by recycling the by-products of combustion. WtE technologies, when equipped with proper pollution control systems, can contribute to clean energy production and reduce greenhouse gas emissions. Many European WtE plants are also exploring Carbon Capture, Utilization, and Storage (CCUS) technologies to further reduce their carbon footprint.

4. European cities are adopting the principles of the circular economy, which emphasizes reusing, recycling, and recovering resources. WtE fits into this model by converting waste into valuable resources. The heat generated during incineration can be used for district heating, and materials like metals and minerals recovered from waste can be reused in production, reducing the strain on natural resources.

5. There are over 500 WtE plants operating in major European cities like Paris, Vienna, Copenhagen, and Barcelona. These plants contribute to sustainable urban development, turning waste into clean energy. As technology improves, WtE will play an even more significant role in Europe's sustainable future.

Which of the following best paraphrases the underlined sentence in paragraph 5?

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.

PLASTIC AND THE ENVIRONMENT

Plastic is a material we use every day. The first plastics were made more than 100 years ago from parts of plants. Plastics are now made from oil, coal and natural gas. We are using up these things so fast that the Earth's supplies may run out. Because of this, scientists are investigating new ideas for making plastics from plants such as sweet potato, bamboo and flax.

Things made from plastic can be useful for people but bad for the environment. Some plastics can last for a long time without wearing out, and can be difficult to get rid of when not needed. They can remain in rubbish dumps called landfill sites for hundreds of years. Landfills can be smelly, ugly, and harmful to our planet.

Recycling is a good way to get rid of unwanted plastics. Recycled waste materials can be used

again to make new products. This can be difficult as different types of plastic need to be recycled in different ways. Some kinds of plastics can be melted down and used to make new things such as bags and bottles. Others can be made into fibres (strands of material) for clothing.

Another way to protect the environment is to use canvas bags for shopping rather than plastic

ones. A lot of plastic objects can also be reused. Plastic bottles can be refilled many times, rather than throwing them away once they are empty. Unwanted plastic goods such as CDs and toys can be sold or given away to charity shops.

The phrase "get rid of" in paragraph 2 is closest in meaning to ______.

Read the following passage and choose the correct answer that best fits each of the following blanks.

Scientists from the State University of New York recently conducted a test that found tiny pieces of plastic in bottled water. (28)_________ examined 250 bottles from nine countries and discovered that more than 90% of them (29)_________ microplastic particles. Sometimes, thousands of these tiny plastic pieces were in a liter of water. Only 17 bottles were plastic-free, with an average of ten plastic particles per liter.

The companies responsible for bottled water claim that their production (30)_________ the highest quality standards. However, scientists and doctors express concerns, even though there is no proof that the smallest plastic particles can harm the body. Most of the plastic is turned into waste and leaves the body through feces.

Apart from bottled water, plastic particles (31)_________ in beer, tap water, seafood, and even in the air. Bottled water is currently the fastest-growing beverage globally, with around $150 billion worth sold worldwide. It is essential for millions of people (32)_________ lack access to safe drinking water.

Read the following passage and choose the best answer to each of the following questions from 23 to 30.

1. Megafires, which were once rare, are becoming more frequent. Over the past 40 years, the number of acres burned by wildfires in the United States has risen by 1,000 percent. Scientists believe that climate change is a key reason for this increase. Warmer and drier weather, along with earlier snowmelt, means that the dry season is now longer, leaving forests more vulnerable to fires.

2. In addition, past land management policies have also made the problem worse. For many years, the U.S. Forest Service focused on putting out all wildfires. However, people did not understand that some forests have evolved to burn. Occasional small fires remove undergrowth and allow new trees to grow, which helps keep the forests healthy.

3. During the 20th century, when forest rangers fought every fire, large amounts of dead wood built up in the forests. This created the perfect conditions for larger, hotter fires. When a fire starts in these areas, it is more likely to become a megafire. Unlike regular wildfires, megafires can permanently change the landscape. For example, the 2011 Las Conchas megafire in New Mexico turned some forested areas into grasslands.

4. Some areas, like Florida and Australia, have used controlled burns to reduce the damage caused by wildfires. These fires are set deliberately to burn away dead matter without harming living plants. However, the U.S. Forest Service currently spends much of its budget fighting megafires, which are becoming more common each year.

5. In an ironic feedback loop, megafires are not only fueled by climate change, they also contribute to it by releasing greenhouse gases into the atmosphere. As a result, megafires could become even more common in the decades ahead.
