There are many different (36) __________ that can be used for biomass energy. Common examples include wood from forests, specific crops grown for energy production like corn or sugarcane, and even waste from farms or cities. For instance, agricultural residue like straw, or organic garbage from our homes, can be converted into useful energy instead of being thrown away.

The most common way to convert biomass into energy is through direct combustion. In this process, the biomass is burned to produce heat. This heat is often used to boil water, which creates high-pressure steam. This steam (37) __________ then be used to turn a turbine, which powers a generator to (38) __________ electricity for homes and industries.

In societies around the world, 'third places'—locations that are neither home (the first place) nor work (the second place)—play a vital role in community life. These are neutral grounds where people can gather, interact, and build relationships. In modern Vietnam, one particular type of establishment has claimed this title with remarkable energy: the coffee shop. From bustling city centers to quiet suburban streets, cafes have become an integral part of the social fabric, serving as the nation's unofficial living rooms.

For Vietnamese teenagers, the coffee shop is more than just a place to get a drink; it has become an extension of their social lives. After school, groups of friends can be seen occupying large tables, laptops open, and textbooks spread out. The combination of free, reliable Wi-Fi, a comfortable air-conditioned environment, and the freedom to stay for hours makes these cafes an essential resource for both studying and socializing. It's a space that offers independence from home and a more relaxed atmosphere than a library.

The appeal of coffee shops extends far beyond the youth. For a growing number of freelancers and entrepreneurs, cafes serve as flexible and affordable offices. Business professionals also use them for informal meetings, finding that the neutral setting encourages open conversation. Coffee shops provide the perfect blend of a professional and relaxed atmosphere, so they have become a popular alternative to traditional office spaces. This trend has not only changed how people work but has also significantly contributed to the local economy.

Vietnam's coffee scene is diverse, generally falling into two main categories. First are the large, domestic chains like Highlands Coffee or The Coffee House. These are known for their consistency, standardized menus, and strategic locations in busy areas, making them reliable choices for work or quick meetings. The second category consists of thousands of independent, uniquely designed cafes. These smaller spots pride themselves on their unique ambiance, specialty coffee beans, and personal touch, attracting customers looking for a more creative and intimate experience.

However, the immense popularity of this culture has its consequences. As more people flock to cafes, many popular spots, especially on weekends, have become incredibly crowded, making it difficult to find a seat or a quiet corner. This high demand has also led to a gradual increase in prices, potentially making a daily coffee habit an expensive luxury for students and young professionals. The challenge for Vietnam's coffee culture is to maintain its welcoming, community-focused spirit while navigating the pressures of its own success.
