Năm 1077, quân dân nhà Lý kháng chiến thắng lợi hoàn toàn chống quân xâm lược nào?

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.

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

     [I] As the world grapples with the finite nature of fossil fuel reserves and the detrimental impact of climate change, the future of energy undeniably lies in renewable sources. [II] Scientists and engineers are making substantial advancements in the development of technologies that more efficiently harness solar, wind, hydro, and geothermal energy. [III] Although the transition to these renewable sources presents significant challenges, it is also regarded as a pivotal step towards establishing a sustainable and resilient energy system. [IV]

     One of the most promising advancements in renewable energy is the enhancement of solar panel efficiency. Progress in photovoltaic technology has led to the creation of panels that convert a higher proportion of sunlight into electricity. Likewise, wind turbines are becoming more and more efficient. They are capable of generating power even under low-wind conditions. These innovations are essential for making renewable energy more feasible and accessible to a broader population.

     However, the transition to renewable energy is fraught with obstacles. The intermittent nature of sources like solar and wind necessitates reliable storage solutions to ensure a consistent power supply. Although battery technology has seen significant improvements, further advancements are imperative to meet growing demand. Moreover, new infrastructure for distributing renewable energy requires expansion and upgrading to accommodate these new power sources.

     The economic impact of transitioning to renewable energy is another critical consideration. While the initial investment in renewable energy infrastructure can be substantial, the long-term benefits include reduced energy costs and job creation in the green energy sector. Governments and private enterprises are increasingly acknowledging the necessity of investing in renewable energy projects, which is crucial for fostering innovation and diminishing reliance on fossil fuels.

     Ultimately, the future of energy hinges on our capacity to innovate and adapt. By continuing to invest in research and development, improving infrastructure, and addressing economic and technical challenges, we can transition towards a more sustainable and environmentally friendly energy system.
