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.

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

SCREEN TIME: MENTAL HEALTH MENACE OR SCAPEGOAT?

    "Have smartphones destroyed a generation?" Jean Twenge - a psychology professor at San Diego State University - asked in her controversial book, iGen. In the book, she argues that those born after 1995 are facing "a mental-health crisis", and she believes it can be linked to growing up with their noses pressed against a screen. Her newest study provides more support for that connection, showing that teens who spent more than an hour or two a day interacting with their gadgets were less happy on average than those who had more face time with others.

    Twenge's conclusions have come up against criticism in the past. Some have accused her work of oversimplifying or overlooking data that may tell a slightly different story. Twenge recognises that her study suggests only a link between screen use and psychological well-being. A possible explanation is that kids are running to their screens to escape from the things in life that are making them unhappy. However, the surveys can't say whether screen time directly changes teens' mental health, the research states.

    Philanthropist Melinda Gates, whose three children were also born after 1995, wrote in The Washington Post, "phones and apps aren't good or bad by themselves, but for adolescents who don't yet have the emotional tools to overcome life's problems, they can aggravate the difficulties of growing up."

    At the same time, she said, kids are learning on their devices and connecting in novel ways. Other studies have explored the connection between social media and isolation and how "likes" activate the brain's reward centre. Some analyses have found that moderate use of these technologies is not harmful in itself and can even improve children's social skills and build emotional strength.
