The process begins when large quantities of old newspapers are collected from recycling centers. Before they can be used, they (36) __________ be sorted to remove any glossy paper or plastic items. Once sorted, the paper is fed into special machines that shred it into very small, fine pieces. The paper must (37) __________ this initial breakdown to create the base material for the insulation.

(38) __________ converts the paper from a simple sheet into a fluffy, fibrous material. Next, the shredded paper is treated with non-toxic chemicals, most commonly boric acid. This is a crucial step in order to make the final product a fire retardant, which means it helps to prevent the spread of fire. Not only is the material treated for safety, but it (39) __________ becomes more resistant to pests and mold.

After the chemical treatment, the damp mixture is dried. This step is carefully controlled to ensure the insulation has the right density and texture. The end result is a loose-fill material that is light and (40) __________ as an insulator. Because of its eco-friendly origins and performance, it is often considered one of the (41) __________ sustainable insulation options available on the market.

(42) __________, the journey from a discarded newspaper to high-performance building insulation is a remarkable example of modern recycling.

For many teenagers in Vietnam and around the world, playing video games is a favorite pastime. But when gaming evolves from a casual hobby into a professional career, it becomes a high-stakes sport where victory is measured in milliseconds. Top Vietnamese teams like GAM Esports don't just rely on talent; they invest heavily in technology to gain a competitive edge. This transformation of gaming into a professional discipline shows that success at the highest level is about much more than just playing the game well.

The foundation of a professional player's setup is their hardware. Unlike the standard equipment a casual gamer might use, a pro's gear is specifically chosen for maximum performance. This includes monitors with extremely high refresh rates (240Hz or even 360Hz), which display action more smoothly and allow for faster reaction times. They use lightweight mice with high-precision sensors to ensure their aim is perfect. Mechanical keyboards provide tactile feedback and faster response, where every keystroke is registered instantly. Having the right hardware is crucial because it removes physical limitations and allows a player's skill to be the only deciding factor.

Beyond the hardware, the invisible world of data analytics plays a massive role. Professional teams employ coaches and analysts who use specialized software to break down every second of gameplay. This software tracks everything from a player's mouse movements and map positioning to their decision-making patterns under pressure. By studying this data, coaches and analysts can pinpoint weaknesses, identify opponent habits, and develop effective counter-strategies. When they present these findings to the team, it's like having a secret playbook that reveals how to win.

Finally, technology is essential for fostering team synergy. In team-based games like League of Legends or Valorant, clear and instant communication can be the difference between a coordinated attack and a disastrous defeat. Players use professional-grade headsets that eliminate background noise and ensure every callout is heard perfectly. Teams also use private servers and communication platforms to practice complex strategies and review past matches together, building a level of coordination that is impossible to achieve in a casual environment.

In conclusion, the world of professional esports is a testament to how technology can elevate a pastime into a serious athletic endeavor. From the physical hardware that enhances player reflexes to the sophisticated software that guides strategy, technology is at the heart of modern competitive gaming. So, the next time you see a professional team lifting a trophy, remember the incredible amount of science and preparation that contributed to their victory.
