Read the following passage about climate change 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.

           Climate change refers to the long-term alteration of temperature and typical weather patterns in a place. This phenomenon is largely driven by human activities, particularly the burning of fossil fuels such as coal, oil, and gas, which increase the concentration of greenhouse gases in the atmosphere. They trap heat from the sun, leading to global warming and causing severe weather events, such as hurricanes, floods, and droughts, to become more frequent and intense. Climate change impacts nearly every region of the world and affects the natural environment, economies, and human health.

           As temperatures rise, polar ice caps and glaciers are melting at alarming rates, contributing to rising sea levels. Coastal regions face an increased risk of flooding, and many low-lying islands are at risk of disappearing entirely. Additionally, higher temperatures lead to the warming of oceans, affecting marine ecosystems and causing coral bleaching, which threatens biodiversity and the livelihoods of millions of people who depend on fishing.

            [I] The consequences of climate change are not just environmental; they also affect human society in significant ways. [II] Changes in weather patterns disrupt agriculture, leading to crop failures and food shortages in vulnerable regions. [III] Furthermore, climate change is linked to health issues such as respiratory diseases, heat strokes, and the spread of diseases carried by insects, like malaria and dengue fever. [IV]

           To combat climate change, a coordinated global effort is necessary. Governments, organizations, and individuals all have roles to play in reducing greenhouse gas emissions and promoting sustainable practices. Shifting to renewable energy sources, such as wind, solar, and hydropower, is essential. Additionally, conserving forests and investing in technology that captures carbon dioxide from the atmosphere can help mitigate the effects of climate change and pave the way for a healthier planet.

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  accustomeLoud 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.

Based on the passage, how does noise affect psychological and physical health in industrial societies?
