The life cycle of a frog is a remarkable journey of transformation, known as metamorphosis. This process begins with a large cluster of eggs, called frogspawn, laid in or near water. From each jelly-like egg hatches a tiny aquatic creature called a tadpole. At first, it looks more like a small fish than a frog, possessing a long tail for swimming and lacking any limbs.

During its initial stage, the tadpole is perfectly adapted for life underwater. It breathes using special organs called (21) __________, which extract oxygen directly from the water, just as fish do. Its primary diet consists of algae and other small plant matter, which it scrapes from surfaces with its tiny mouth. The tadpole spends its days swimming actively, growing bigger and stronger in preparation for the dramatic changes that are to come.

Gradually, the transformation begins. First, back legs start to sprout, and a little later, front legs appear. (22) __________, the tadpole's body begins preparing for life on land. As these limbs grow, the tadpole starts to take on the appearance of a miniature frog, although it still has its long, powerful tail. This intermediate stage is often called a 'froglet'.

Internally, even more significant changes are occurring. The gills that were essential for underwater life begin to disappear as a pair of lungs develops. Its body starts (23) __________ its long tail for energy and nutrients, causing it to shrink. A biologist once explained that the tail was gradually absorbed, not simply dropped off. This absorption is a crucial part of fueling the final, energy-intensive stage of metamorphosis.

Finally, the tail vanishes completely. If the tadpole (24) __________ this final stage successfully, it would not be able to survive out of the water. With its new lungs, strong legs, and no tail, the young frog is now fully equipped for a life on land. It can hop away from the water's edge to hunt for insects, a very different diet from what it ate as a tadpole. The transformation from an aquatic herbivore to a terrestrial carnivore is, to all intents and purposes, complete.

Virtual Reality (VR) technology is rapidly transforming how we interact with digital content, offering incredibly immersive experiences. From gaming to education, VR headsets are opening new portals, and one intriguing application is virtual travel. Imagine exploring the pyramids of Giza or the bustling streets of Tokyo from your living room, feeling almost truly there. This raises a fascinating question for our connected world: Can a VR headset ever truly replace the profound experience of a real trip? The advancement in graphics and haptics suggests it’s certainly becoming a powerful alternative. [I]

[II] It offers unprecedented accessibility, allowing individuals with physical limitations or financial constraints to visit places they might otherwise never see. Cost-effective and time-efficient, VR removes the need for expensive flights, visas, and lengthy itineraries. Moreover, it provides a safe way to experience dangerous or remote environments, from ocean depths to Everest peaks, or even historical sites no longer existing. For many, VR travel is an incredible tool for exploration, broadening horizons without leaving home.

[III] For young people in Vietnam, this discussion about VR's role in travel is particularly relevant. Vietnam has a strong commitment to technological development, with major conglomerates like FPT and Vingroup heavily investing in tech education and innovation. This focus means that Vietnamese youth are highly exposed to cutting-edge technologies like VR, often having opportunities to try them in tech centers or schools. This familiarity fosters a unique perspective on how emerging tech can shape future experiences, making the question of VR replacing real travel a tangible topic.

[IV] Despite its impressive capabilities, VR travel currently falls short of replicating a genuine journey. A headset cannot convey the full sensory richness of a place – the distinct smell of street food, the feeling of humid air, the sound of a distant temple bell, or the tactile sensation of ancient stone. Crucially, it lacks the spontaneous human interactions, deep cultural immersion, and unpredictable discoveries that define real-world exploration. These non-visual elements are integral to the memories and personal growth that come from genuine travel.

Ultimately, while VR travel offers an incredible, accessible, and often educational experience, it is more accurately seen as a powerful complement rather than a true replacement for physical travel. For 14-15 year olds, who are part of a generation that will witness VR becoming increasingly common, understanding this distinction is key. It helps to appreciate the opportunities technology provides for learning and experiencing the world, while also recognizing the irreplaceable value of authentic, multi-sensory engagement with different cultures and environments. The future likely holds a blend of both.
