This is the text (if you need help).
Research shows that insects feel pain. A researcher said people don't think insects feel pain. He said insects know what dangerous things to stay away from. He said he knew that insects could sense 'pain' but didn't know that an injury could make insects more sensitive.
The researchers looked at injured fruit flies. They damaged one leg on fruit flies and let it heal. After it healed, the flies were more sensitive. The flies remembered the pain. They tried to protect their legs. It was more sensitive until it died. The researcher wants to research human pain. He wants to make drugs to stop pain.
