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.”

Read the following passage about the A Vision of a Harmonious Multicultural Society 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 31 to 40.

By 2050, our world will have undergone remarkable transformations in how different cultures coexist. The walls that once divided nations are vanishing into thin air as global citizens embrace diversity like never before. Technology will serve as the great equalizer, with translation devices making language barriers a thing of the past. In urban centers worldwide, neighborhoods will showcase architectural influences from multiple cultures, creating spaces where everyone feels at home regardless of their background. Public spaces will feature gardens with plants from different continents, symbolic of how various cultures can thrive together in one environment.

[I] Education systems will prioritize cultural literacy alongside traditional subjects. [II] Schools will teach world history from multiple perspectives rather than through a single cultural lens. [III] Students will routinely participate in virtual exchange programs, allowing them to form friendships with peers around the world without leaving their classrooms. [IV] Government policies will recognize that a harmonious multicultural society requires institutional support, with resources allocated to community centers where cultural exchange happens organically through shared meals, festivals, and collaborative art projects.

Economic systems will evolve to value diverse approaches to business and innovation. Companies will actively seek employees from varied backgrounds, recognizing that diverse teams create more innovative solutions. Traditional knowledge from indigenous communities will be respected and incorporated into sustainable development practices. The entertainment industry will produce content that authentically represents multiple cultures, moving beyond stereotypes to show the complexity within each tradition. Digital platforms will help preserve endangered languages and cultural practices through accessible archives and learning tools.

The greatest achievement of this harmonious world will be a new understanding of human identity. People will identify with multiple cultural traditions simultaneously without feeling conflicted about their loyalties. Holidays from various traditions will be celebrated collectively, creating new hybrid celebrations that honor multiple heritages. The concept of "us versus them" will gradually fade as people recognize shared values across different traditions. While challenges will remain, the dominant attitude will be one of curiosity rather than fear when encountering differences.

Which of the following is NOT mentioned as a feature of the world in 2050?
