As technology advances, especially in countries like Vietnam with a strong focus on innovation, a new question arises: can a virtual reality (VR) trip replace a real one? VR headsets promise to transport us to the Eiffel Tower or the pyramids of Giza from our living rooms. For a generation growing up with technology, this idea is becoming a regular part of the conversation about future travel.

The advantages of VR travel are clear. It offers access to places that are too expensive, far away, or even impossible to visit, like Mars. The experience can be incredibly immersive, making you feel like you are truly there. For students, it is a powerful educational tool, bringing history lessons to life. It’s a convenient and affordable way to explore the world from home.

However, critics argue these virtual experiences are ultimately superficial. A real trip involves all five senses: the smell of street food, the warmth of the sun, and the taste of a local fruit. VR cannot replicate these sensations. Furthermore, it misses the element of human connection—interacting with local people and their culture. While virtual tours look real, critics say they lack the soul of genuine travel.

In conclusion, while VR is a remarkable achievement, it is unlikely to replace real travel. Instead, it serves as a wonderful supplement. It can inspire someone to book a real trip after virtually visiting a city or act as a preview of a destination. VR is a window to the world, but not the same as stepping through the door.

While they offer a convenient way to travel short distances, their rapid rise has brought unexpected problems. A major concern is safety, (37) __________. These incidents often happen because people ride without helmets or on sidewalks where they conflict with walkers.

Another significant issue is how scooters are left after use, (38) __________. This 'dockless' model, while convenient for users, creates a real headache for city officials. Finally, the environmental benefits are not as clear-cut as they seem, (39) __________. Therefore, cities must develop better regulations (40) __________.

A. especially when they replace walking or cycling rather than car trips

B. to ensure these vehicles are a true benefit to the community

C. as many riders and pedestrians suffer injuries in accidents involving them

D. creating hazards for people with disabilities and disrupting public order
