Have you ever wondered how skyscrapers stand so tall? A key reason is reinforced concrete. By itself, concrete is very strong when you push or squash it, a property known as compressive strength. However, it's weak when you pull or stretch it; it can crack easily. To solve this problem, engineers add steel bars, called rebar, inside the concrete before it hardens. Steel is excellent at resisting pulling forces, a property called tensile strength. By combining concrete and steel, engineers get the (25) __________ of both worlds.

This combination creates a composite material that is incredibly strong under both compression and tension. (26) __________ allows engineers to design much larger and more complex structures than they could with just concrete alone. The process involves (27) __________ a steel cage and then pouring wet concrete around it. The concrete hardens and grips the steel tightly.

Gone are the days when YouTube and TikTok were purely for music videos and funny clips. A new wave of creators, often called 'Edu-Tubers', is transforming these platforms into virtual classrooms. They produce high-quality videos that explain complex topics, from science experiments to literary analysis, offering a fresh alternative to traditional learning methods. For many Vietnamese students, this shift is already a familiar reality, providing help with challenging school subjects.

The primary appeal of this new educational landscape is its accessibility. With just an internet connection, students can find tutorials on almost any topic at any time. This content is often presented in a more dynamic and engaging way than a standard textbook. Furthermore, most of this knowledge is free, removing financial barriers to extra help. This makes learning resources more accessible to a wider range of students who need support.

However, this digital classroom is not without its dangers. The biggest challenge is verifying the information. Not every creator is an expert, and misinformation can spread quickly. Unlike a school textbook, online content is not always checked for accuracy. Therefore, it is crucial for students to learn how to evaluate sources and not blindly trust everything they see. Finding a reliable source is more important than ever.

In conclusion, social media can be a powerful educational ally, but it requires a smart approach. It offers a vast library of resources that can supplement schoolwork and make learning more enjoyable. The key is for students to become critical consumers of information, able to distinguish credible content from misleading noise. By doing so, they can turn their screen time into a productive learning experience.

Consequently, we are motivated to share more content, often subconsciously tailoring it to what we think will receive the most 'likes'. (39) __________.
