Before the Romans, builders faced a major challenge. They wanted (25) __________ larger and stronger buildings, but their techniques were limited. They mostly used the 'post-and-lintel' system—two vertical posts with a horizontal beam on top. This was simple, but not very strong over long distances.

The invention of the arch was a game-changer. Arches were much (26) __________ than straight beams and could support more weight. The secret was their curved shape and a special stone at the very top, the keystone. This design (27) __________ a key role in distributing weight down to the ground.

Living in a hot, humid climate like Vietnam's often means a daily battle to stay comfortable. Traditional fabrics like cotton absorb sweat but dry slowly, leaving you feeling sticky. Polyester, on the other hand, doesn't breathe well. For years, these were the main choices for everyday clothing. However, material science is now offering a high-tech solution to this common problem, moving beyond the limits of conventional textiles.

The secret lies in 'smart textiles' designed specifically for cooling. These innovative fabrics work in two main ways. First, they have excellent moisture-wicking properties, meaning they pull sweat away from the skin to the fabric's surface where it can evaporate quickly. This process mimics the body's natural cooling system but enhances it. Second, some advanced materials can manage thermal radiation, allowing the heat our bodies produce to escape more efficiently into the environment.

The benefits of these cooling fabrics are clear. They provide superior comfort during hot weather, making daily activities more pleasant. Furthermore, by helping people stay cool, these textiles could potentially reduce the reliance on air conditioning, leading to energy savings. While these high-tech materials are often more expensive than cotton or polyester, their popularity is growing as more people recognize their advantages. Local brands in Vietnam are also starting to incorporate these fabrics into their collections.

The future of clothing in warm climates looks promising. As technology improves and becomes more affordable, we can expect to see more of these smart textiles in our wardrobes. From school uniforms to office wear, science is paving the way for a future where our clothes actively help us beat the heat, making everyday life in places like Vietnam significantly more comfortable.

While remote work offers flexibility, the move away from traditional offices has social side effects we are only now beginning to understand. The office wasn't just a place to complete tasks; it was a social hub. Spontaneous conversations in the hallway or during lunch were vital for team bonding and creative brainstorming, (37) __________. These informal interactions often led to new ideas and a stronger company culture.

As we spend more time working alone, we risk losing these important social connections. (38) __________. Without the daily routine of commuting and seeing colleagues, the line between work and personal life can blur, (39) __________. Many companies are now trying to find a balance, perhaps through a hybrid model. (40) __________.

A. leading to burnout and a feeling of being disconnected

B. This isolation can negatively affect mental well-being and job satisfaction

C. Ultimately, they must recognize that building a strong team requires more than just digital tools
