Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.

Read the following passage 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 23 to 30.

          Happiness is a universal goal, yet its ingredients differ across societies and cultures. For some, safety and security are paramount, as demonstrated by Singapore. Known for its strict laws and highly regulated environment, Singapore provides a clean, orderly, and safe place for its citizens. The government ensures access to basic necessities such as housing and healthcare, significantly reducing poverty and promoting equality. While personal freedoms may be limited, many Singaporeans find satisfaction in the stability and quality of life their country offers, showing that happiness can stem from collective security.

        In contrast, Mexico highlights the importance of social connections in achieving happiness. Despite challenges like poverty and limited access to essential resources, Mexicans often prioritize relationships with family, friends, and neighbors. Simple acts like sharing meals or gathering in the community foster a sense of belonging and emotional well-being. Psychologists have long noted that feeling part of a larger social group can be a powerful source of happiness, even when material wealth is scarce. For them, the joy derived from relationships often outweighs material concerns.

       The role of money in happiness, however, is often debated. In Mexico, many individuals live in similar financial conditions, reducing the pressure of economic competition. When neighbors lack expensive possessions, individuals are less likely to feel dissatisfied with their own circumstances. This suggests that relative wealth and equality may have a stronger influence on happiness than absolute income.

       Ultimately, there is no universal recipe for happiness. Factors like security, freedom, social bonds, and financial equality all play a role, but their importance varies depending on individual and cultural values. Happiness, therefore, remains a deeply personal and multifaceted pursuit, shaped by our unique perspectives and circumstances.
