(23) __________ This simple rule addresses several potential dangers and conflicts that can arise in shared public spaces. (24) __________

An alloy is a material made by combining a metal with at least one other element, which could be another metal or a non-metal. This process is done to give the final material new and useful (25) __________. For instance, bronze is an alloy of copper and tin. Thousands of years ago, people (26) __________ this combination, leading to the Bronze Age. Today, from the stainless steel in our kitchens to the aluminum alloys in airplanes, they (27) __________ a crucial role in modern technology and industry.

So, how is an alloy made? The most common method involves heating the main metal until it becomes liquid. Then, the other elements (28) __________ added to the molten metal, and the mixture is stirred well to ensure it is uniform. A uniform mixture is very important. (29) __________, if the elements are not mixed properly, the alloy will be weak in some spots. Finally, the liquid is cooled and solidifies, creating materials (30) __________ are stronger, lighter, or more resistant to rust than pure metals.

Self-driving cars, also known as autonomous vehicles (AVs), represent one of the biggest goals in the world of technology. Major companies are investing billions of dollars to create cars that can operate entirely without a human driver. This futuristic technology promises to make roads safer and give people more free time during their commutes.

In Vietnam, however, this dream encounters a unique reality. The traffic in major cities like Ho Chi Minh City is famous for its chaos, with thousands of motorbikes weaving through lanes in unpredictable patterns. Developing an AV that can safely navigate this environment is an extremely ambitious goal. Vietnamese company VinFast is actively tackling this challenge, developing and testing its own autonomous features for local road conditions.

So, how do these cars 'see' the world? They rely on a combination of advanced cameras and sensors to build a complete, 360-degree map of their surroundings. An Artificial Intelligence (AI) brain then processes all this data to make split-second driving decisions. When they detect a pedestrian or another vehicle, the AI must react instantly and correctly. The technology is often described in 'Levels of Autonomy,' and achieving the higher levels where the car is fully independent is a very complex task.

For teenagers who experience this busy traffic every day, the concept of a robot driver is both fascinating and a little daunting. Could a machine ever truly understand the unwritten rules of Vietnam's roads? As this technology continues to evolve, it forces us to consider important questions about safety, trust, and the future of transportation in our crowded cities.

The rise of remote work has been a game-changer for many employees, offering unprecedented flexibility. People can now manage their professional responsibilities from the comfort of their homes, avoiding long commutes and creating a more personalized work environment. (37) __________. However, this shift has also introduced a significant challenge known as the "remote work paradox." Instead of feeling more relaxed, many remote workers report increased stress and burnout.

The main reason for this is the blurring of boundaries between work and personal life. (38) __________. Laptops are always accessible, and notifications can interrupt evenings and weekends. (39) __________. To combat this, experts suggest establishing clear routines and dedicated workspaces. (40) __________. By being proactive, remote workers can enjoy the benefits of flexibility without falling into the burnout trap.

A. This constant connectivity often leads to employees working longer hours than they would in a traditional office setting

B. Setting firm start and end times for the workday is crucial for maintaining mental well-being

C. This newfound freedom allows for a better work-life balance in theory

D. Without the physical separation of an office, it becomes difficult to mentally "switch off" from work
