Sure, I can help simplify the language and knowledge for the questions. Here are some simplified questions for grade 4 learners:

1. Have you learned about how to stay safe when using the internet? (Yes/No)
2. Do you know how to protect your personal information online? (Yes/No)
3. Have you heard about cyberbullying and how to deal with it? (Yes/No)
4. Can you recognize and avoid things online that might try to trick or scam you? (Yes/No)

Please note that these questions are simplified for grade 4 learners and may not cover all aspects of online safety practices.
