Read the passage below and choose A, B, C or D.
Although noise, commonly defined as unwanted sound, is a widely recognized form of pollution, it is very difficult to measure because the discomfort experienced by different individuals is highly subjective and, therefore, variable. Exposure to lower levels of noise may be slightly irritating, whereas exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise produced as a by-product of our advancing technology causes physical and psychological harm, and detracts from the quality of life for those who are exposed to it.
Unlike the eyes, which can be covered by the eyelids against strong light, the ear has no lid, and is, therefore, always open and vulnerable; noise penetrates without protection. Noise causes effects that the hearer cannot control and to which the body never becomes accustomed. Loud noises instinctively signal danger to any organism with a hearing mechanism, including human beings. In response, heartbeat and respiration accelerate, blood vessels constrict, the skin pales, and muscles tense. In fact, there is a general increase in functioning brought about by the flow of adrenaline released in response to fear, and some of these responses persist even longer than the noise, occasionally as long as thirty minutes after the sound has ceased.
Because noise is unavoidable in a complex, industrial society, we are constantly responding in the same way that we would respond to danger. Recently, researchers have concluded that noise and our response may be much more than an annoyance. It may be a serious threat to physical and psychological health and well-being, causing damage not only to the ear and brain but also to the heart and stomach. We have long known that hearing loss is America's number one nonfatal health problem, but now we are learning that some of us with heart disease and ulcers may be victims of noise as well. Fetuses exposed to noise tend to be overactive, they cry easily, and they are more sensitive to gastrointestinal problems after birth. In addition, the psychic effect of noise is very important. Nervousness, irritability, tension, and anxiety increase affecting the quality of rest during sleep, and the efficiency of activities during waking hours, as well as the way that we interact with each other.

Read the following passage about urban farming and mark the letter A, B, C, or D to indicate the best answer to each of the following questions from 23 to 30.
Urban farming, or the practice of growing food within city limits, has gained popularity worldwide. As cities expand and populations grow, there is increasing pressure on food supplies, making urban farming an appealing solution. From rooftop gardens to community plots, urban farms can help produce fresh, local food in areas that are typically food deserts. Additionally, they provide green spaces in densely populated areas, contributing to environmental sustainability.
Urban farming also has social benefits. It encourages community engagement and provides educational opportunities for residents. People can learn about sustainable agriculture, food production, and environmental conservation. Furthermore, urban farms can offer job opportunities, particularly in underprivileged neighborhoods, where employment options are often limited. By creating jobs and encouraging healthy eating, urban farms positively impact the health and well-being of local communities.
However, urban farming is not without its challenges. One significant issue is space; cities are crowded, and land is scarce. Finding suitable plots for farming can be difficult and expensive. There are also regulatory hurdles, as some cities have strict zoning laws that limit agricultural activities. Additionally, urban soil can be contaminated with pollutants, making it unsuitable for food production. Despite these obstacles, innovative solutions, such as hydroponics and vertical farming, are making urban farming more feasible.
In the future, urban farming could play a vital role in food security. As climate change and urbanization continue, local food sources will become increasingly important. By reducing dependency on long supply chains, urban farming can ensure that cities remain resilient in the face of global challenges.

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.
