Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

In an era of increasing global awareness, debates around sustainable practices such as fair trade, organic farming, and recycling are gaining prominence. Farmers in developing countries are among the most vulnerable people, dependent on world commodity markets, middlemen, and unpredictable weather. 

(I)Fair trade arrangements aim to support cooperative groups by guaranteeing prices above the world market rate and additional bonuses. (II) However, critics argue that fair trade may not lift a country out of poverty. (III)They claim that most of the money generated from sales goes to wealthy countries that promote these products. (IV)In fact, only about 5% of the sale price of a fair-trade chocolate bar (retailing for £1.73 in the UK) reaches the poor country.

Another significant trend is the rise of organic food, marketed as being free of chemicals, which appeals to consumers concerned about the dangers of chemicals in food. These chemicals are suspected of causing various health problems, including cancer and developmental issues in children. Despite these concerns, British farmers have not converted to organic farming in large enough numbers to meet the demand. As a result, supermarkets often import organic vegetables from distant countries, contributing to higher greenhouse gas emissions due to transportation. Environmentalists are now urging consumers to buy locally grown vegetables, even if they are pesticide-treated, suggesting a good wash can minimize the risk.

In recent years, a shift has occurred in how we handle waste. Once content to bury it in landfills or dump it at sea, we are now encouraged to recycle and treat waste as a resource. This shift has led to more widespread kerbside collections for various materials like paper, plastic, and metal. However, recycling has unintended consequences. Most of the UK's recyclables are sent to China or India, which incurs additional environmental costs from transportation. In these countries, workers often sort waste under dangerous conditions. Sometimes, materials that are sorted at home still end up in landfills because the market for them fluctuates.

While efforts to promote sustainability are commendable, they require constant evaluation to ensure they truly benefit people and the environment, rather than creating new inequalities or environmental harm.

Where in the passage does the following sentence best fit? "This growing fair-trade market has distributed hundreds of millions of pounds to over 50 million people worldwide."

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 31 to 40.

Sustainable development has become a priority worldwide, as nations work to balance economic growth with environmental preservation. [I] Sustainable practices are critical to ensure that natural resources are conserved for future generations, while also meeting today’s economic needs. [II] Many countries have invested in green technologies to reduce carbon emissions and slow climate change.

[III] However, achieving sustainability involves more than just technology; it requires a collective shift in mindset towards reducing waste, reusing materials, and protecting biodiversity. [IV] According to the United Nations, sustainable development must incorporate social equity, economic progress, and environmental stewardship to be effective.

A key factor driving sustainability efforts is the awareness of limited resources. The earth’s resources, such as freshwater, fossil fuels, and fertile land, are finite, and overuse can lead to scarcity. In recent years, many nations have implemented regulations to control the extraction and consumption of resources, aiming to curb excessive demand and reduce environmental impact. For example, many cities have introduced restrictions on single-use plastics and have promoted recycling programs as a means to encourage responsible waste management.

While developing countries may prioritize industrial growth to boost economic development, developed nations often focus on reducing their carbon footprint and promoting eco-friendly policies. This disparity can lead to challenges in international relations, as countries negotiate agreements on emissions and resource use. Organizations like the United Nations work to bridge these gaps through global frameworks that encourage cooperation, but disparities in priorities and resources can hinder progress.

Increasing public awareness about environmental sustainability has been another critical component of these efforts. Through education and media campaigns, individuals are encouraged to adopt environmentally conscious practices, such as reducing energy consumption, using public transport, and supporting local economies. By making small adjustments in daily life, individuals contribute to broader global sustainability goals, ultimately promoting a healthier planet for future generations.

Which of the following can be inferred from the above passage?

Read the following passage about the urban shift and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40. 

Pollution and Its Global Impact

[I] Pollution is one of the most pressing issues in the modern world, affecting not only the environment but also public health and global economies. [II] While urbanization and industrialization have brought significant progress, they have also introduced severe environmental challenges. [III] Reducing pollution requires a comprehensive approach that includes public awareness, technological innovation, and stricter environmental policies. [IV]

Air pollution is among the most widespread forms of environmental degradation. It stems from emissions by vehicles, factories, and deforestation, leading to harmful effects on both human health and the climate. According to the United Nations, fine particulate matter (PM2.5) causes millions of premature deaths annually. Water pollution, caused by untreated waste, agricultural runoff, and oil spills, destroys marine ecosystems and threatens human water supplies. Similarly, soil pollution—often overlooked—results from pesticides, heavy metals, and industrial waste, severely impacting agriculture and biodiversity.

While governments worldwide have implemented measures to combat pollution, individual action is equally essential. Reducing plastic consumption, opting for sustainable transportation, and recycling waste can significantly lessen environmental harm. Moreover, industries must adopt cleaner production methods, such as renewable energy and green technology. However, these solutions are effective only when paired with robust educational campaigns that encourage people to understand and address pollution’s consequences.

Despite these efforts, the problem persists, especially in developing nations, where economic constraints hinder environmental policies and waste management systems. At the same time, wealthier countries often export waste to poorer regions, exacerbating the issue. Experts stress that international cooperation is essential to tackle pollution on a global scale. Unless all nations contribute, the planet’s resources and ecosystems may face irreversible damage.

According to the passage, which of the following is TRUE?

Read the following passage about The Benefits of Outdoor Activities and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Engaging in outdoor activities has become increasingly popular in recent years. Not only do these activities provide an escape from the daily grind of life, but they also offer numerous physical and mental health benefits. Hiking, cycling, and team sports are just a few examples of outdoor activities that can enhance well-being.

First and foremost, outdoor activities encourage physical fitness. Regular participation in activities like hiking or cycling helps individuals maintain a healthy weight and improve cardiovascular health.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

[I] Green living, often referred to as sustainable living, encourages individuals to adopt environmentally friendly practices in their daily lives. [II] This lifestyle includes reducing waste, conserving natural resources, and promoting eco-friendly habits, which collectively help to minimize the negative impact on the environment (Davies & Mulligan, 2017). [III] Although green living requires effort and adjustment, its benefits for the planet and future generations are substantial. [IV]

One of the fundamental aspects of green living is waste reduction. This can be achieved through practices like recycling, composting, and reducing single-use plastics. According to a report by the Environmental Protection Agency (EPA), recycling and composting can significantly decrease the amount of waste sent to landfills, which helps reduce greenhouse gas emissions and pollution (EPA, 2021). Additionally, adopting reusable items such as water bottles and shopping bags minimizes reliance on plastic, which is crucial for protecting ecosystems and wildlife.

Another key component of green living is energy conservation. Simple changes, like switching to LED light bulbs and using public transportation, can reduce an individual's carbon footprint. A study by the International Energy Agency (IEA) shows that energy efficiency improvements, if widely implemented, could decrease global energy demand by up to 40% by 2050 (IEA, 2019). By conserving energy, individuals not only lower their utility bills but also contribute to the reduction of carbon emissions, which is essential for mitigating climate change.

Green living also involves making conscious choices about the products we consume. This includes opting for sustainably sourced goods, supporting local businesses, and choosing organic produce. Sustainable agriculture practices reduce the need for chemical pesticides and fertilizers, which can harm both the soil and water sources (Smith & Taylor, 2020). By making informed purchases, consumers can support eco-friendly industries and help create a demand for greener alternatives.

The phrase "carbon footprint" in paragraph 3 could be best replaced by _______.

Read the following passage about human life expectancy and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30. 

An engine is a machine that creates mechanical motion from energy. In order to do this, an engine frequently requires some type of fuel to burn. Nowadays, many engines are used to power cars and other forms of transportation. These vehicles most commonly have an internal combustion engine and rely upon gasoline for power. However, there are several types of engines that can use alternative energy sources. Many people are trying to switch to them because gasoline, which is a fossil fuel, creates pollution and is also a non-renewable resource.

These days, engines that are able to burn biofuels are somewhat common. Biofuels are fuels that are made from biological material, such as corn, soybeans, and sugarcane. These biofuels burn cleanly, so they produce much less pollution than fossil fuels. In some countries, such as Brazil, cars with biofuel engines are standard. In fact, most of the cars in Brazil have engines that can operate on either gasoline or biofuel.

A second type of alternative engine is the electric engine. Cars with electric engines have been common for decades. Most are being used in hybrid cars at the moment. These are vehicles that have both a gasoline-powered engine and an electric one. In many cases, the gasoline-powered engine is used to operate the car at high speeds on expressways. The electric engine is utilised for city driving. One benefit of hybrid cars is that as the gasoline-powered engine runs, it simultaneously recharges the electric engine.

A third type of alternative engine is the hydrogen engine. It utilises hydrogen fuel cells, which convert hydrogen into electricity that can power the car These days, there are many cars and buses that rely upon hydrogen engines. However, there are some problems associated with this type of engine. The hydrogen used in the engine must be processed from other materials, and it is also difficult to store. As a result, vehicles that run on hydrogen are expensive.

Alternative energy sources create less pollution and are often renewable sources of energy. It is hoped that more and more innovations help the use of alternative energy sources become easier and easier.
