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.

The Koromi trend has taken social media by storm, influencing fashion, lifestyle, and online communities worldwide. Originating in Japan, Koromi is characterized by a unique blend of gothic aesthetics, cute elements, and bold self-expression. Unlike mainstream kawaii culture, which emphasizes bright colors and cheerful themes, Koromi embraces darker shades, punk influences, and a rebellious attitude. This fusion of edginess and playfulness has resonated with many young people looking for an alternative form of self-representation.

Social media platforms like TikTok and Instagram have played a crucial role in popularizing the trend, as influencers and fashion enthusiasts share their interpretations of the Koromi style. The trend's rise is also linked to a growing appreciation for individuality and alternative fashion in contemporary youth culture.

Beyond fashion, the Koromi trend has influenced makeup styles, accessories, and even music preferences. Many followers of this aesthetic incorporate dark eyeliner, edgy clothing, and playful accessories to create a distinctive look. As more people adopt the Koromi lifestyle, brands have started releasing special collections inspired by the trend. However, some critics argue that the commercial adoption of Koromi dilutes its original meaning and turns it into a passing fad rather than a genuine subculture.

While Koromi's popularity continues to grow, it remains a niche trend compared to mainstream fashion movements. Its impact, however, is undeniable, as it encourages self-expression and challenges conventional beauty standards. Whether it will evolve into a long-lasting cultural phenomenon or fade away as another internet-driven craze remains to be seen.
