Hibernation is a remarkable survival strategy that some animals use to get through the harsh winter months. It's often described as a deep sleep, but it's a much more complex biological process. Animals like bears, groundhogs, and some bats enter this state to avoid periods of cold weather and food shortages. This dormant state allows them to survive until conditions improve.

The main reason for hibernation is the lack of available food during winter, a period (21) __________ plants die back and insects disappear. To survive, animals must find a way to make their energy reserves last. They do this through hibernation, a special process that helps them conserve energy. So, instead of searching for food that isn't there, they find a safe place, like a cave or a burrow, to rest.

During hibernation, an animal's body undergoes incredible changes. Its metabolism, the process that converts food into energy, slows down dramatically. The heart rate and breathing become very slow and shallow. Body temperature also drops significantly. Because of these changes, very little energy is needed to keep the animal alive. All the necessary power (22) __________ from the body fat the animal stored during the autumn.

This state of deep inactivity can last for several weeks or even months. Hibernating animals don't usually sleep continuously (23) __________ the spring. They often wake up for short periods to eat stored food or to excrete waste before going back to sleep. The main (24) __________ of this process is to minimize energy use, which is crucial for survival when external resources are unavailable.

However, not all animals that are inactive in winter are true hibernators. Some, like squirrels, enter a lighter state of sleep called torpor and wake up frequently. True hibernation is a profound physiological change that is different from normal sleep. It is a powerful adaptation that shows how resilient wildlife can be in the face of environmental challenges.

Globally, television talent shows possess immense power to transform music landscapes, elevating niche genres to mainstream popularity. Programs like "The Voice" or "X Factor" consistently discover and present talent to millions, catapulting artists and their unique styles into unprecedented fame. This global trend of TV as a powerful cultural accelerator strongly resonates in Vietnam. There, a single groundbreaking show dramatically reshaped public perception and consumption of an entire music genre, proving television's profound influence on cultural trends and youth interests. It demonstrated how a well-crafted reality competition can completely alter a nation's musical taste. [I]

For years, rap music in Vietnam existed largely in the underground, a vibrant but niche scene confined to dedicated fans. Rappers honed their craft in small venues and online communities, creating music that often spoke to specific subcultures and youthful experiences. While critically acclaimed within its circles, mainstream appeal remained elusive. Many Vietnamese households, particularly older generations, knew little about rap or viewed it as a loud, aggressive, or foreign genre, far removed from the popular ballads and pop music dominating national airwaves. [II] It was an art form struggling for broader recognition.

This dynamic dramatically shifted with the arrival of "Rap Việt" on Vie Channel - HTV2. The show, infusing global hip-hop culture with distinctly Vietnamese flavor, brought the underground scene directly into living rooms nationwide. Suddenly, artists like Dế Choắt and GDucky transitioned from niche figures to household names. "Rap Việt" showcased rap's lyrical depth, creative versatility, and emotional power, captivating an audience far beyond the genre's original fan base and transforming rappers into national idols. [III]

The impact of "Rap Việt" on Vietnamese youth was particularly profound. Teenagers, previously dabbling in rap, became avid followers, discussing performances, critiques, and contestant narratives. The show made rap accessible, fashionable, and undeniably cool, directly influencing playlists and fashion choices. [IV] It validated a genre many young people enjoyed but felt misunderstood by adults. This widespread acceptance also spurred new collaborations, commercial opportunities, and a significant increase in Vietnamese rap music production, cementing its place in popular culture and fostering a new generation of artists.

'Rap Việt' didn't just popularize artists; it fundamentally redefined rap's position in Vietnam's music industry and cultural fabric. It proved that a well-produced television program, combining raw talent with compelling storytelling, could dismantle old perceptions and bridge underground art with mainstream appreciation. The show's success is a testament to media's power in shaping public taste and inspiring new musicians and fans. Its legacy ensures Vietnamese rap is no longer a niche sound but a powerful, integral voice in the nation's vibrant and evolving musical landscape.
