Read the following passage about powering 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.

     As we continue to face the impacts of climate change, having a green environment has become increasingly important to the future of our society. To achieve this, the world is shifting towards green energy, and two particular types of energy at the centre of this movement are solar power and wind power.

     [I] Solar power is all about harnessing the energy of the sun by using solar panels to convert sunlight into usable electricity. [II]. Moreover, solar panels are perfect for installation on a small scale, such as in private homes, since they require very little maintenance and have a long lifespan. [III] However, the ability to generate solar power depends on the time of day and weather conditions. This means that solar panels are often less useful if they are installed in places where sunny weather is not typical. [IV]

     Wind power, on the other hand, involves converting the energy of the wind into electricity using large turbines. Wind power doesn’t produce any greenhouse gases, but it is not ideal for private use since turbines require consistent care. However, wind farms can be installed on a large scale and are able to produce electricity continuously regardless of the time of day. This means that if there were more investments in wind power, it could be a viable way to provide energy for major cities and even for whole regions.

     Wind and solar power contribute significantly to a green environment by reducing our reliance on fossil fuels, helping us cut down on pollution and slow climate change. Additionally, using renewable energy sources helps promote spending on sustainable development by creating new career opportunities in the green energy sector.

     For now, the biggest challenge of adopting green energy is the costs associated with installation and infrastructure, but the benefits unquestionably outweigh the downsides. If we want to stop the climate crisis and create a better and more sustainable future, green energy sources will undoubtedly be the key.

According to paragraph 2, which of the following is NOT an advantage of solar power?

Trong nguyên tử, khối lượng một hạt electron và một hạt proton lần lượt là 9,11.10\(^{-28}\) g và 1,673.10\(^{-24}\) g. Hỏi khối lượng của một hạt proton gấp bao nhiêu lần khối lượng một hạt electron?

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.

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.

Biting into a ripe, juicy fruit brings a smile to many people’s faces. But eating that same fruit a week before it is ripe probably wouldn’t be as enjoyable! Unripe fruits are often hard and bitter, but that serves a purpose. The hard exterior of an unripe fruit protects the developing seed inside. After a seed fully develops inside the fruit, the fruit changes color, softens, and gets sweeter to become more attractive to animals and humans. These organisms eat the fruit and spread its seeds, ensuring the plant’s survival and regrowth.

But how does a fruit ripen? The ripening process involves many complex chemical reactions. When a fruit ripens, it goes through a chemical change. A chemical change happens when bonds within molecules break, and the atoms that once formed them regroup into new molecules. Chemical changes are irreversible. Once a fruit ripens, it cannot become unripe again.

One molecule responsible for this chemical change is ethylene. Ethylene (C2H4) is a colorless gas made up of carbon and hydrogen atoms. (I). It is a naturally occurring molecule in the atmosphere. (II). It is also an important plant hormone. (III). Plants release ethylene through the growing tips of roots, flowers, and ripening fruit. (IV). Although ethylene serves other purposes in plants, one of its main purposes is to trigger the chemical reactions that cause fruits to ripen. As the fruit matures, oxygen in the air helps stimulate the production of ethylene. This ethylene production is a signal that begins fruit ripening. For that reason, unripe fruits have low levels of ethylene, while ripe fruits have higher levels of ethylene. Most fruits produce ethylene and respond to ethylene in the atmosphere.

Although fruits require ethylene to ripen, different types of fruits respond to this molecule in two distinct ways: non-climacteric fruits and climacteric fruits. Non-climacteric fruits do not ripen after harvesting. They produce very little ethylene of their own. Climacteric fruits, on the other hand, continue to ripen after they are picked. These fruits produce a large amount of ethylene. Climacteric fruits can also speed up the ripening process of other fruits nearby since they release high levels of ethylene into the air.
