Read the following passage about the Exploring The Universe 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.

Science is a vast and fascinating field that seeks to understand the natural world and the universe beyond[I]. It encompasses various disciplines, including physics, chemistry, biology, and astronomy[II]. Each of these areas contributes to our understanding of complex phenomena, [III]. For instance, scientific research has led to significant breakthroughs in medicine, renewable energy, and environmental conservation[IV]. In this essay, we will explore the impact of science on our lives, particularly focusing on space exploration.

One of the most intriguing aspects of science is space exploration. Humans have always looked to the stars, wondering what lies beyond our planet. The launch of satellites and manned missions has allowed us to gather valuable information about the cosmos. For example, NASA's Mars Rover has provided insight into the potential for life on other planets. Through meticulous research and data collection, scientists can analyze soil samples and atmospheric conditions, paving the way for future explorations.

Space exploration also raises critical questions about our existence and the future of humanity. As we continue to advance technologically, the prospect of colonizing other planets becomes more plausible. This endeavor could serve as a solution to the challenges we face on Earth, such as overpopulation and resource depletion. However, ethical considerations must guide these efforts. We must ensure that we do not repeat the mistakes of history, such as the exploitation of natural resources and indigenous populations.

Moreover, scientific advancements have enabled us to develop technologies that enhance our understanding of the universe. Telescopes and space probes allow us to observe distant galaxies, study black holes, and uncover the mysteries of dark matter. Each discovery leads to new questions, further fueling our curiosity and drive for knowledge. The concept of the multiverse, for instance, challenges our understanding of reality and pushes the boundaries of scientific thought.

In addition to exploring the universe, science plays a crucial role in addressing pressing issues on Earth. Climate change, for example, is a significant concern that scientists are actively investigating. Through climate models and data analysis, researchers can predict future trends and propose solutions to mitigate the effects of global warming. Public awareness and education are essential in fostering a collective response to environmental challenges.

As we reflect on the wonders of science, it is clear that its contributions extend far beyond mere knowledge acquisition. Science empowers us to make informed decisions about our health, environment, and future. By fostering a culture of curiosity and critical thinking, we can inspire future generations to continue exploring the unknown.

The word “curiosity” in OPPOSITE in meaning to_______.

Read the following passage about the Second Acts That Inspire 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.

Life often presents us with unexpected challenges that force us back to the drawing board. Whether due to personal setbacks, career changes, or unforeseen circumstances, the courage to begin again can lead to remarkable transformations. Many inspiring individuals have shown that it's never too late to reinvent oneself and pursue new dreams. Throughout history, countless people have overcome seemingly impossible situations through sheer determination.

[I] Take J.K. Rowling, for instance. Before becoming a literary sensation, she was a struggling single mother living on welfare. [II] Her determination eventually paid off when her books became a global phenomenon, proving that setbacks can become stepping stones to success. [III] This remarkable turnaround demonstrates how resilience and unwavering belief in oneself can overcome seemingly insurmountable obstacles. Despite facing depression and financial hardship, she never gave up on her dreams. [IV]

Colonel Harland Sanders' story is another testament to the power of starting anew. At the age of 65, when most people contemplate retirement, he found himself struggling financially after his restaurant failed. Instead of giving up, he traveled across America, sleeping in his car while pitching his chicken recipe to restaurant owners. His recipe for success wasn't just about the perfect blend of herbs and spices; it was about persistence and determination. After facing over 1,000 rejections, he finally established Kentucky Fried Chicken, which grew into a global empire. His unwavering spirit and dedication inspired generations of entrepreneurs worldwide.

These inspiring stories remind us that failure is not final, but rather a chance to redirect our path. Every setback carries the seed of an equal or greater opportunity, and sometimes the end of one chapter is simply the beginning of a better one. The key lies in having the courage to take that first step, even when the future seems uncertain. As these remarkable individuals have shown, it's never too late to rewrite your story and create a powerful second act. Their journeys teach us that persistence and courage ultimately lead to success.

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 31 to 40.

Working on Your Workout

(I) Although appreciating a balanced diet and regular exercise, most people do not know how to exercise properly. Consequently, they usually rush through their workouts, or they make the same common workout mistakes. (II) Exercising the right way is important for people who are worried about their health and their appearance. (III) However, if someone is not working out properly, they will not see the results they want. Therefore, training experts have devised tips to teach people how to exercise correctly in order to achieve the greatest health benefits. (VI)

One of the most common workout mistakes is doing the same routine over and over again. This does not challenge your muscles, and it can actually prevent muscles from growing and repairing themselves. Instead of always sticking to the same old workout, it is important to change your routine every six to eight weeks. It is also important to add a variety of workouts to your routine, such as swimming, yoga, or biking, to make sure your whole body stays fit. This will help make your workouts more interesting, and benefit your health and muscle development as well.

Another mistake people tend to make is to work out too hard, too often. Your body needs to rest between workouts; otherwise, no progress will be made. It is best to keep the number of hard workout routines to no more than two per week. Then, for those who don’t want to get off schedule by skipping a day, shorter workouts of about twenty minutes can be used on other days. For more variety in workouts, you could also plan an easier routine for forty to sixty minutes between days of shorter, more intense workouts. Experts recommend, however, taking at least one day off completely each week, especially after several hard workout days in a row.

In reality, no one is perfect. However, if you want to make a difference in your overall health, there are some things you can do. Stretch before and after every workout. Do not rush your routine, and do not work out too little or too much. Remember not to make these common workout mistakes, and always have fun while exercising!

The word "they" in paragraph 1 refers to:
