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. Today, reinforced concrete is one of the (28) __________ common building materials worldwide. Its (29) __________ makes it essential for everything from bridges and dams to foundations and high-rise buildings. It truly can (30) __________ the test of time.

The Fields Medal is often called the 'Nobel Prize of Mathematics.' Awarded only once every four years, it is the highest honor a mathematician under the age of 40 can receive. Winning this medal is not just a personal victory; it is a global recognition of extraordinary talent and groundbreaking work that pushes the boundaries of human knowledge. It represents the very peak of intellectual achievement in the field.

In 2010, Vietnam celebrated a historic moment when Professor Ngô Bảo Châu was awarded the Fields Medal. This was a significant achievement, earning him recognition for his proof of a complex mathematical idea called the Fundamental Lemma. The news, widely reported by media like Dân Trí, filled the nation with immense pride and showed the world the brilliant potential of Vietnamese minds on the global stage.

What does it take to reach such heights? While genius-level intelligence is necessary, it is not enough. The journey requires immense dedication and perseverance to overcome difficult challenges. Furthermore, modern mathematical breakthroughs are rarely a solitary effort; they often depend on collaboration with other bright minds. These personal qualities are just as important as the ability to work with complex numbers and theories.

Professor Châu's success has had a powerful effect, particularly on Vietnam's youth. His story serves as a profound inspiration, demonstrating that with hard work and passion, they too can compete and excel at the highest international levels. It encourages a new generation to pursue academic excellence in fields like science and technology, proving that a Vietnamese name can stand among the world's greatest thinkers.

It's a common belief that we should always try to be happy. However, psychologists have discovered something strange called the 'happiness paradox': the idea that actively chasing happiness can sometimes make us feel worse. (37) __________. For example, if you believe a birthday party must be the 'best day ever,' any small problem can feel like a huge failure.

(38) __________. Instead of enjoying the moment, we start to analyze our feelings, wondering why we aren't as happy as we think we should be. (39) __________. A more effective path to well-being might involve pursuing meaningful activities and relationships, rather than happiness itself.

B. True contentment often comes as a byproduct of a well-lived life, not as a direct goal

C. Research suggests that accepting all our emotions, both positive and negative, is a healthier approach

D. When we set high expectations for happiness, we often feel disappointed when reality doesn't match
