Read the passage carefully. Choose an option (A, B, C or D) that best answers each question from 16 to 22.

1. Like many emergency responders, Nicholas Groom is used to stress at work.  On the one hand, the stress can be helpful. “I find that when attending a serious incident, it helps me to maintain focus on the situation,” Nicholas Groom said. On the other hand, the work can be highly pressurized. “Too much stress can impair your ability to make decisions,” he adds. And Groom is not alone in his complicated relationship with stress.

2. Many people believe that there should be a balanced amount of stress. In other words, not too much stress so you’re not overwhelmed but not too little stress so you don’t feel unmotivated. After all, some anxiety is motivating; think of the adrenaline before a deadline or the excitement before a competition.  Sports fans sometimes even talk about a “gene” in some athletes who seem to play best in the decisive final moments of a match. Furthermore, many psychologists claim that performance in many situations increases with stress up to a point. Of course, any stress can cause harm when it’s prolonged. To take just one example, a long-term high heart rate is linked to cardiovascular diseases. And additional stressors, such as financial pressures or psychiatric issues, clearly affect how beneficially someone can respond to stress.  

3. So is there a way to harness stress to your advantage while being mindful of its detrimental long-term effects? One key factor is to avoid, whenever possible, the point when stress leads to mental and physical collapse. Crystal Wernicke, 30, has always used stress as a motivator. But juggling between parenting, a full-time job, a voluntary role and financial troubles at the same time became too much and eventually led to a two-month period of illness. Another factor is the presence of control. For those who feel powerless over their situation, stress is unlikely to be beneficial. But with some autonomy over stressful tasks, we are better able to convert that pressure into higher performance.

4. When it comes to stress and how it affects your performance, it’s helpful to recognize the variations in personality, type of stress and task that affect the level of pressure you are under, as well as understanding tools you can use to control and harness that stress. Ultimately, it’s not helpful to take a one-sided view, either demonizing or glorifying stress. As James C Quick, a management professor at the University of Texas, sums up: “Stress can be the kiss of death as well as the spice of life.”

Why was Crystal Vernicke sick for two months?

a. One useful suggestion is to reduce the use of private cars and choose public transport instead, which helps to lower air pollution and decrease traffic problems in cities.

b. In the long term, following such suggestions can lead to a more sustainable and responsible way of living.

c. These actions not only protect the planet but also create cleaner and healthier communities for people.

d. Another effective idea is to recycle materials such as paper, glass, and plastic, so that natural resources are saved and less waste is produced.

e. Improving the environment requires small but important changes in daily life.

Read the following passage about endangered languages and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questionsfrom 23 to 30.

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.
