The Sun is a star at the center of our solar system, and it is the source of (25) __________ of the energy on Earth. But how does it produce so much light and heat? The answer lies in its core, where a process called nuclear fusion happens. This process involves hydrogen atoms combining under immense pressure and temperature. This transformation (26) __________ a huge amount of energy in the form of light and heat.

(27) __________, this energy travels from the Sun’s core to its surface and then radiates out into space. Without this process, life on Earth as we know it would be impossible. If the Sun suddenly stopped this fusion, our planet (28) __________ a cold, dark rock.

Hip-hop and rap music have traveled a long way. Initially, the genre was a voice for communities on the margins, offering a way to talk about social realities. What started as an underground movement in specific neighborhoods has grown into a global phenomenon, dominating music charts and influencing fashion and language. This evolution from a niche style to a major cultural force is a fascinating story seen all over the world.

In Vietnam, the story is similar. For years, Vietnamese rap, or 'V-Rap', existed in a small subculture. It was music made by and for a specific community, often shared online or at small events. This early scene was praised for its raw energy and authentic lyrics, which reflected the uncensored experiences of young people. However, it was largely invisible to the wider public, who generally preferred traditional pop ballads.

This changed dramatically with television talent shows like 'Rap Việt'. These programs brought V-Rap directly into millions of homes. Suddenly, rappers once known only within their niche communities became national celebrities. This massive exposure was the key factor that pushed the genre into the mainstream. The shows created a new generation of fans and demonstrated rap's commercial potential in Vietnam.

As a result of this newfound fame, the lives of V-Rap artists have transformed. Many now sign large commercial contracts, appear in advertisements, and release hits that blend rap with other popular styles. This journey shows how a passionate subculture can capture a nation's attention, changing the landscape of Vietnamese popular music and proving that rap is here to stay.

Wind energy is often praised as a clean alternative to fossil fuels, but it has a significant downside for flying animals. The massive, rotating blades of wind turbines pose a deadly threat to birds and bats. (37) __________. As a result, conservationists are growing concerned about the placement of new wind farms.

For birds, a key problem is "motion smear," where the fast-moving blades become nearly invisible. (38) __________. For bats, the situation is also critical, as they seem to be attracted to the turbines, perhaps mistaking them for tall trees where they might roost. (39) __________.

Finding effective solutions is therefore urgent. Researchers are now testing methods like painting one turbine blade black to increase its visibility. (40) __________. Balancing our need for clean energy with wildlife protection is a major challenge for the 21st century.

A. This visual illusion means that even birds with excellent eyesight can fail to see the danger until it is too late

B. Early results suggest this simple change can reduce bird fatalities significantly

C. Every year, hundreds of thousands of these animals are killed by collisions with turbines

D. This misjudgment leads them directly into the path of the deadly blades
