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.

       Since the birth of the car in 1886, transport in big cities has changed a lot. And it is no wonder that many experts think that there will be extraordinary changes in the next few decades.

       As technology develops, highways, skylines, subways will be all transformed. Smarter roadways and highways in cities outfitted with loT sensors will process all kinds of data in real time and alert users of the best transport options. Weather, crashes, traffic conditions will be communicated to users and smart stops will be found everywhere providing renewable energy, green hydrogen or even greener energy, ensuring efficiency and safety on every highway. Tunnels will also be a smart choice because of the reduction of traffic congestion. Underground roads will be built in 3D with a lift system which will take vehicles deep underground and will allow traffic to attain the greatest speed without intersections.

       There will also be innovations in the sky. Air taxis are not a new idea, but in the future they will be completely environment-friendly. Aviation gasoline will be no longer used. Green energy will be in place and cost-effective air taxis will enable people to travel from one busy urban city to another in record time.

       New technologies such as Al and the rollout of 5G will pave the way for fully autonomous innovation. Cars will not be the only thing to go autonomous. Freight trucks, cargo vehicles, air taxis will all benefit from this technology and that is why the term ‘driver’ will become extinct.

       Transport will go green. Electric or hydrogen power will be mainstream. There will still be issues to solve such as safety, speed and cost, and of course governments will need to make new traffic laws.

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. 

TikTok is a popular social media app where people can create and share short videos [I]. It started in China in 2016 as Douyin [II]. The app is known for its easy-to-use tools that let users add music, effects, and filters to their videos [III]. People of all ages enjoy making and watching TikTok videos, which can be funny, educational, or creative [IV].

One of the reasons TikTok is so popular is because of its algorithm, which shows users videos that match their interests. When you open the app, you see a personalized feed called the "For You" page. This page is different for everyone and updates with new videos all the time. Users can also follow their favorite creators to see more of their content.

TikTok has become a platform for trends and challenges. Many users participate in dance challenges, lip-syncing, and other viral activities. These trends can spread quickly, reaching millions of people in a short time. Because of this, TikTok has influenced music charts, fashion, and even language. Songs that go viral on TikTok often become hits on other platforms too.

The app is also a space for education and advocacy. Many creators use TikTok to share knowledge about various topics, such as science, history, cooking, and fitness. Others use the platform to raise awareness about social issues and promote positive change.

In addition to individual creators, many brands and businesses use TikTok for marketing. They create content to engage with their audience, often using popular trends and challenges to promote their products.

However, TikTok has faced some criticism and challenges. Concerns about privacy and data security have led to scrutiny from governments. Despite these issues, TikTok still remains one of the most downloaded apps in the world.
