Read the following passage about generation gap 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.
[I] The generation gap refers to the differences in attitudes, values, and beliefs between older and younger generations. [II] With rapid advancements in technology and shifting societal norms, the generation gap has become more apparent. [III] As younger generations grow up with modern technology and global connectivity, they frequently experience a world vastly different from that of their parents and grandparents. [IV]
One of the key reasons behind the generation gap is the rapid pace of technological change. Older generations, who grew up in a world without the internet, smartphones, or social media, often find it difficult to relate to the digital lifestyles of younger people. On the other hand, younger generations have been exposed to technology from a young age, shaping their values and communication styles. Additionally, differences in social values, such as views on work, family, and personal freedom, also contribute to the gap. These differing experiences create misunderstandings and a lack of common ground between generations.
The consequences of the generation gap can be significant, especially in family dynamics and workplaces. In families, the divide can lead to conflicts between parents and children, as each generation struggles to understand the other’s worldview. In the workplace, generational differences may affect teamwork, communication, and productivity. Younger employees may prioritize flexibility and innovation, while older generations may value stability and traditional work ethics. These differences can lead to friction, decreased collaboration, and a sense of alienation among coworkers.
To bridge the generation gap, open communication and mutual understanding are essential. Both older and younger generations need to be open to learning from each other and appreciating different perspectives. For instance, older generations can offer wisdom and experience, while younger generations can share their knowledge of technology and new trends. Encouraging intergenerational dialogue through family discussions, mentoring programs, or team-building activities in the workplace can help foster respect and collaboration. By recognizing and embracing their differences, both generations can work together to create a more harmonious society.

Read the following passage about lifelong learning 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.
My father was an enthusiastic traveller, but as he got older, he increasingly suffered from what he called “travel fever,” a vivid term for the acute anxiety felt before a journey, essentially due to uncertainty about all the things that could go wrong. Sadly, this eventually stopped him from going on holiday. Then I, too, started to suffer similar apprehension, so I consulted a psychotherapist. She recommended a small piece of cognitive behavioural therapy, which involved acknowledging the mental and physical symptoms of anxiety, but telling myself that these were essentially indistinguishable from feelings of excitement about the prospect of a journey. This reframing of my feelings has been reasonably effective – it’s one way of dealing with uncertainty.
It’s not just the uncertainty of travel that we all have to face. None of us knows what is going to happen, or what is currently going on outside our immediate knowledge, or the vast majority of what has happened in the past. Uncertainty has been called the “conscious awareness of ignorance,” and there is a lot we are ignorant about. We must navigate through life without complete information, and this fundamental uncertainty is an inescapable aspect of human existence.
We all have to live with this uncertainty and, as a statistician, it’s been my job to try to analyse data and assess some of the risks we face. (I)But some deal with uncertainty with more equanimity than others. (II) Psychological studies, as well as our own experience, reveal a wide variation in people’s responses, including those that are cognitive (how we think), emotional (how we feel), and behavioural (what we do). (III)For example, when faced with uncertainty, do you deny it or acknowledge it, does it put the wind up you or make you courageous, do you try to avoid it or approach it?(IV)
Of course, your response may depend on the context, just as an individual’s appetite for risk-taking can vary across different areas of their lives. I have known people who seemed to take huge physical risks, yet were very cautious with money. Numerous scales have been developed to measure how well people can deal with uncertainty, based on responses to statements ranging from “Unforeseen events upset me greatly” to “When it’s time to act, uncertainty paralyses me.” Those who score highly, and find it difficult to tolerate uncertainty, may also be at increased risk of clinically significant anxiety and depression.
Which of the following is NOT mentioned as a factor influencing people’s responses to uncertainty in paragraph 3?
