Suspension bridges are amazing structures that can span huge distances. Their strength comes from a clever design that distributes weight. The road, or deck, where cars drive doesn't hold its own weight. Instead, it hangs (25) __________ strong vertical steel ropes called suspenders. These suspenders transfer the load of the deck and the traffic to two massive main cables above.

If the main cables were not incredibly strong, the entire structure (27) __________ collapse. (28) __________, the towers are not the final destination for the force.

Imagine scrolling online and seeing a video of your favorite singer saying something shocking. It looks real, but is it? Welcome to the world of deepfakes, highly realistic videos created by artificial intelligence (AI). This technology can make it seem like anyone has said or done anything, creating a huge challenge for telling what is real from what is fake online.

The threat is growing. While often used for fun, deepfakes can also be used in sophisticated scams and to spread misinformation. In Vietnam, for example, cybersecurity experts like Ngo Minh Hieu (HieuPC) and government authorities have begun public campaigns to warn people about these dangers. Their goal is to prevent citizens from losing money or believing false stories that are designed to cause confusion and distrust.

So, how can you spot a fake? Look for small clues. Deepfake videos often have strange details, like unnatural eye blinking, weird shadows or lighting, or a robotic-sounding voice. It is important to look closely and think critically before you believe or share something. Taking a moment to check if a video is authentic can protect you and others from being tricked by this advanced technology.

Ultimately, the best defense against deepfakes is a sharp mind. As technology evolves, we must also evolve our skills as digital citizens. By questioning what we see, verifying information from trusted sources, and thinking before we share, we can help build a safer and more trustworthy online environment for everyone. Being a critical thinker is no longer optional; it is essential.
