Read the following passage about the Reimagining International Cooperation 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.

Global environmental governance is changing how countries work together. Nations now understand that pollution, climate change, and resource problems cross borders. Traditional agreements between countries are not enough anymore. New approaches include businesses, local communities, and citizen groups working with governments. This all-hands-on-deck approach helps create better solutions for our planet. Many successful projects show that when different groups cooperate, they can solve difficult environmental problems that single countries cannot fix alone.

Environmental governance faces many challenges today. [I] Political differences between nations often slow down important decisions. [II] Some countries worry that strict environmental rules might hurt their economic growth. Despite these obstacles, new technologies are helping countries monitor environmental changes better. [III] Satellite data and computer models allow scientists to track forest loss, ocean pollution, and climate patterns. [IV] This information helps leaders make smarter decisions about protecting natural resources.

The future of environmental governance depends on innovation. Digital platforms now connect environmental experts around the world instantly. Young people are bringing fresh ideas through social media campaigns and protest movements. Indigenous communities contribute valuable traditional knowledge about sustainable living practices. Financial institutions are creating new ways to fund green projects in developing countries. These combined efforts are creating a more flexible and responsive system of global cooperation that can adapt to changing environmental conditions more quickly than old-fashioned diplomatic channels.

Effective environmental governance requires balance between global standards and local solutions. While international agreements provide important frameworks, communities need freedom to implement approaches that fit their unique situations. Successful governance models respect cultural differences while maintaining scientific standards. Education plays a crucial role in building public support for environmental policies. When citizens understand environmental issues, they make better choices and hold their leaders accountable. The most promising path forward combines strong international institutions with energetic local action to create lasting environmental solutions.

Read the following passage about the Youth unemployment and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions.

    [I] Youth unemployment has become a pressing issue in Vietnam in recent years, particularly among graduates. [II] As the economy continues to grow, the influx of young people entering the workforce has outpaced the availability of suitable jobs. [III] Various factors contribute to this challenge, leading to significant consequences for both the economy and society. [IV]

    Many factors push young people into unemployment. For instance, a mismatch between education and job market demands often leaves graduates without the skills that employers require. Furthermore, the competitive job market means that even qualified candidates struggle to secure positions. In contrast, there are opportunities that attract youth to urban centers, where industries are more concentrated, providing potential access to better employment prospects and a higher standard of living.

    The impacts of youth unemployment are far-reaching. First, high unemployment rates can lead to increased poverty levels among young adults, which in turn affects their overall well-being and mental health. Additionally, the lack of stable jobs can result in social unrest, as frustrated youth may engage in protests or other forms of activism. Finally, this phenomenon can lead to a brain drain, where skilled young people migrate abroad in search of better opportunities, further depleting the local talent pool.

    Addressing youth unemployment is a complex challenge that requires a comprehensive understanding of its causes and effects. By implementing effective educational programs, fostering entrepreneurship, and encouraging job creation in various sectors, Vietnam can better support its youth, providing them with opportunities for fulfilling careers and contributing to the economy without sacrificing social stability.

The word “their” in paragraph 2 refers to ____

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.

Taking Home the World Cup

Standing just 36 centimeters tall, the FIFA World Cup Trophy symbolizes the pinnacle of football achievement.  Every four years, teams worldwide compete for it, but no one ever takes the trophy home. Made of 18-carat gold, the original trophy remains under FIFA's protection, with winners receiving only a replica. This measure safeguards it from theft, as the trophy has been stolen twice in its history.

The original trophy was made by a French sculptor, Abel LaFleur, and was called the “Jules Rimet Cup,” in honor of the founder of the World Cup tournament. Sometime during the first three World Cup events (1930, 1934, and 1938), the name changed to simply the “World Cup.” Then during World War II, not much was seen or heard of the trophy. It was being kept hidden in a shoe box under the bed of Dr. Ottorino Barassi, the Italian vice-president of FIFA, to prevent it from falling into the hands of the Nazi army. In 1966, the Cup was stolen during a public showing of the trophy prior to the World Cup tournament in England. Luckily, it was found a short time later, none the worse for wear, in a trash container by a little dog named Pickles. Four years later, Brazil earned permanent possession of the original trophy by winning its third World Cup title. Unfortunately, the trophy was stolen a second time in 1983 and was never recovered. The Brazilian Football Association had to have a duplicate trophy made.

(I) After the first trophy became the possession of Brazil’s football association, a new World Cup Trophy for FIFA was designed by an Italian artist, Silvio Gazzaniga, in 1974. (II) This trophy cannot be won outright, but remains in the possession of FIFA, and rest assured they are watching it very closely. Today, World Cup winners are awarded a replica of the trophy that is gold-plated, rather than solid gold like the real one. (III) Gazzaniga’s World Cup trophy weighs almost five kilograms. (IV) Its base contains two layers of a semi-precious stone called malachite, and has room for seventeen small plaques bearing the names of the winning teams---enough space to honor all the World Cup champions up to the year 2038. After that, a new trophy will have to be made.

The phrase "none the worse for wear" could best be replaced by:
