Researchers tested over 10,000 people. They were 71 (ask) to research different topics, like how to grow a garden or how to lead a healthier life. Some used AI chatbots while
others used regular web searches. After that, they wrote down 72 they had learned as advice for a friend. What happened? People who searched the web developed 73 (deep) knowledge.
Why? Using AI is like 74 (ride) a bus. You get to the destination fast, but you don't know the way 75 (exact). You just sit and wait for the ride to end. But searching the web is like hiking 76 your own. You have to look at the map, choose the right path, and notice the landmarks like signs or special 77 (building). This brain workout helps you really understand and remember the information.
The study also 78 (find) something interesting. Even when the AI chatbots gave links to websites, 75% of people did not bother to click 79 (they). They didn't want to learn more once they had the fast answer.
So, next time you are curious, do not just ask 80 chatbot for the answer. Be a real explorer! Go information hunting on the web, and your brain will thank you for the extra work.
