The Earth's oceans represent a vast and (35) __________ source of untapped renewable energy. Beyond the familiar power of the sun and wind, the ocean itself provides a consistent force we can harness: the tide. Tidal energy is a method of generating electricity by using the natural rise and fall of sea levels, offering a clean and sustainable alternative to fossil fuels.

This daily movement of water is caused by the gravitational pull of the Moon and Sun. Because the movements of these celestial bodies are known with great accuracy, the resulting tides are extremely (36) __________. The cycle of high and low tides happens every day without fail, which means we can calculate the availability of this energy source far into the future.

To capture this power, engineers place large underwater turbines in areas with strong currents. These machines, which look similar to wind turbines, are designed to withstand the ocean environment. They (37) __________ be placed in specific locations, such as estuaries or narrow channels, where the water flow is strongest. As the tide moves in and out, the water turns the blades of the turbines to (38) __________ electricity.

One of the biggest benefits of tidal power is its reliability. It is much (39) __________ consistent than wind or solar power, which can be affected by changing weather. (40) __________ means that grid operators can depend on a steady supply of energy. Furthermore, the technology is remarkable. Not only (41) __________ it clean and renewable, but its underwater placement also means it has a low visual impact on the landscape.

(42) __________, tidal power is an exciting and growing field of renewable energy. While it is not yet as common as other forms, its potential for providing dependable, clean electricity to coastal regions is enormous. With continued development, the powerful, daily pulse of the ocean could play a key role in our future energy mix.

In a bustling alley in Hanoi's Old Quarter, the scent of star anise, cinnamon, and simmering beef broth fills the air. This is the home of Phở Gia Truyền, a fictional but representative family-run restaurant that has been serving the same, iconic bowl of pho for nearly a century. Every morning, long before the city awakens, the current owner, Mr. Bao, begins the meticulous process passed down from his great-grandfather. For generations of Hanoians and tourists alike, the restaurant is not just a place to eat; it is an institution, a taste of history that has remained unchanged.

For the family, this culinary legacy is a profound source of pride and identity. The secret recipe is their most valuable asset, a treasure that has provided a stable income and secured their place in the community. Loyal customers return year after year, not for novelty, but for the comfort of its consistency. They seek the authentic flavor they remember from their childhoods. This connection to the past and the community is something Mr. Bao cherishes, and he feels a deep responsibility to preserve it for the future.

However, for Mr. Bao's 15-year-old son, Minh, this legacy feels less like a treasure and more like a heavy burden. Minh is a creative teenager with a passion for digital art and modern design. While he respects his family's history, the thought of spending his entire life in a hot kitchen, repeating the exact same steps day after day, feels daunting. The pressure to become the next 'keeper of the flame' is immense. His dreams of attending a university for graphic design clash with his father's expectation that he will one day take over the restaurant.

This dilemma is not unique to Minh's family. Across Vietnam and around the world, many historic family businesses face a similar crossroads. The older generation values tradition and continuity, while the younger generation often seeks personal fulfillment and new opportunities that their parents never had. If they choose to follow their own paths, who will preserve these precious traditions? But if they are forced to sacrifice their dreams, what is the cost to their own happiness and potential?

Ultimately, the story of Phở Gia Truyền poses a difficult question. How can families balance the preservation of a cherished heritage with the individual aspirations of the next generation? Is it possible to adapt a tradition without losing its soul, or is the choice simply between preservation and personal freedom? The answer remains as complex and layered as the broth simmering in Mr. Bao’s kitchen.
