Read the passage below and choose A, B, C or D to fill in each blank.

There are more than one billion cows in the world, and cow farming is a large source of methane emissions. This colorless and odorless gas (631) ____ at warming the earth.

Farmers and companies are developing solutions for (632) _____. In Canada and Brazil, farmers started adding a special ingredient to their animals' feed to reduce cows' methane production. In New Zealand, scientists are working on a vaccine which can cut methane emissions. Rather than stopping methane emissions, a UK company has designed face masks to catch the gas (633) ______.

The masks will allow cows to continue their normal diet but will turn methane into CO2 and water. They can fit comfortably on the cow's head and can be adjusted to different head sizes. Sensors on the masks can notice when methane comes out of the cow's mouth and provide the percentage of the gas (634)_____. This information can also be useful for farmers who can use it to (635) __________ the early signs of disease. For example, if a cow eats less, but produces more methane than usual, it may have a health problem.

It is predicted that the need for beef and dairy products will go up in the coming years. The company developing the methane-catching masks hopes that farmers will start using their invention, which will slow down global warming.

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. (2,5 points)

            [I] Water is one of the most essential resources on our planet, vital for all forms of life. However, increasing demand and pollution are putting immense pressure on our freshwater supplies. [II] According to recent studies, nearly 2 billion people worldwide live in countries experiencing high water stress, leading to a decline in the availability of this precious resource. This situation not only affects drinking water but also agriculture, sanitation, and energy production.

            The primary causes of water scarcity include population growth, urbanization, and climate change. As cities expand, the demand for water increases significantly. Moreover, agricultural practices that rely heavily on water are becoming unsustainable in many regions. Climate change further exacerbates these issues, causing unpredictable weather patterns and extreme droughts, which reduce water availability.

           [III] In response to this growing crisis, everyone must prioritize water conservation. Simple actions, such as fixing leaks, using water-efficient appliances, and practicing mindful consumption, can make a significant difference. Additionally, implementing policies that promote sustainable water management and investing in technologies for water recycling can help mitigate the impacts of water scarcity. [IV]

            Despite these efforts, the challenges remain substantial. It is crucial that we recognize the importance of conserving water and take immediate steps to protect this vital resource for future generations.

Read the following passage about powering 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.

     As we continue to face the impacts of climate change, having a green environment has become increasingly important to the future of our society. To achieve this, the world is shifting towards green energy, and two particular types of energy at the centre of this movement are solar power and wind power.

     [I] Solar power is all about harnessing the energy of the sun by using solar panels to convert sunlight into usable electricity. [II]. Moreover, solar panels are perfect for installation on a small scale, such as in private homes, since they require very little maintenance and have a long lifespan. [III] However, the ability to generate solar power depends on the time of day and weather conditions. This means that solar panels are often less useful if they are installed in places where sunny weather is not typical. [IV]

     Wind power, on the other hand, involves converting the energy of the wind into electricity using large turbines. Wind power doesn’t produce any greenhouse gases, but it is not ideal for private use since turbines require consistent care. However, wind farms can be installed on a large scale and are able to produce electricity continuously regardless of the time of day. This means that if there were more investments in wind power, it could be a viable way to provide energy for major cities and even for whole regions.

     Wind and solar power contribute significantly to a green environment by reducing our reliance on fossil fuels, helping us cut down on pollution and slow climate change. Additionally, using renewable energy sources helps promote spending on sustainable development by creating new career opportunities in the green energy sector.

     For now, the biggest challenge of adopting green energy is the costs associated with installation and infrastructure, but the benefits unquestionably outweigh the downsides. If we want to stop the climate crisis and create a better and more sustainable future, green energy sources will undoubtedly be the key.
