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.

Data privacy means ensuring that our personal information is kept safe and used responsibly by others. In today’s digital world, where information spreads easily, it’s more important than ever to protect our personal data. This highlights the importance of privacy laws.
Laws about data privacy vary globally. For example, in Europe, the General Data Protection Regulation (GDPR) grants individuals rights such as accessing their data, asking for it to be deleted, and knowing how it’s used. Similarly, the California Consumer Privacy Act (CCPA) provides specific rights about personal information to people in California. Knowing these laws helps people understand their rights and what companies must do to keep their data safe. When using websites or apps, it’s essential to read their privacy policies. Emily Davis, a cybersecurity expert, stresses, “Reading and understanding privacy policies allows individuals to make informed decisions about sharing their personal information.”.
To boost your online safety, experts suggest using strong, unique passwords for each account and not reusing them. Enabling two-factor authentication when possible adds an extra layer of security. Equally important, be careful with emails, texts, or calls asking for personal information or money. Scammers often pretend to be real organizations. Always check before giving out personal details or clicking on links from unknown sources. Keep your devices updated with the latest software and security patches to protect against cyber threats. Using trusted antivirus software can also lower the risk of attacks. Privacy advocate Michelle Carter advises, “Being mindful of data sharing and regularly reviewing app permissions helps minimize unnecessary exposure of personal information.”.
Understanding your rights and taking steps to protect your personal information online are essential in today’s interconnected world. By learning about privacy laws, being careful about sharing information, and using strong security measures, you can control your digital presence and keep your privacy safe. Remember, protecting personal data is something we all need to do together to create a safer and more respectful online environment.

Read the following passage about Our Festival Traditions 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 23 to 30.
How Green Are Our Festival Traditions?
Festivals are a time of celebration, bringing happiness and joy through various traditions. However, many of these traditions are not environmentally friendly and could harm our planet. To ensure a sustainable future, it is important to reconsider some of these practices and explore more eco-friendly alternatives.
One common festival tradition is the release of balloons and sky lanterns, especially in countries like China, India, and Japan. These beautiful sights are believed to bring good luck and carry wishes to the sky. Unfortunately, the environmental impact is significant. Balloons and lanterns often end up as litter, which is difficult to decompose. The frames of sky lanterns can harm wildlife, and animals often mistake balloons for food, putting them at risk. Furthermore, lanterns have been known to cause wildfires, endangering both nature and human safety.
Another tradition that raises concerns is fireworks. In countries like Australia and the US, fireworks displays are a staple during festivals. While they are visually stunning, fireworks release harmful chemicals into the air, contributing to pollution and poor air quality. Similar to sky lanterns, fireworks can also cause fires, which can be devastating to both the environment and communities.
Lastly, Christmas trees, whether real or artificial, are a central part of holiday decorations in homes and businesses worldwide. Real trees, when discarded, release methane and carbon dioxide, two harmful greenhouse gases that contribute to global warming. Although artificial trees can be reused for several years, their production involves harmful pollutants, and when they end up in landfills, they take centuries to decompose, further burdening the environment.
In conclusion, while festival traditions bring joy and excitement, many of them have negative environmental consequences. By choosing more sustainable practices, we can celebrate in ways that are both enjoyable and environmentally responsible, ensuring that future generations can also enjoy these traditions.
