Homework:

What role should parents, schools, and governments play in ensuring children’s online safety?

I think parents should show their children the videos that are good for their children's age. Because I've learned that when parents show their children good videos, children become kind and good people. But if parents show bad videos, they become rude and bad people. The government should tell the teachers to educate children in good ways.

This is such a very well-thought response, Seo Yeon! Keep it up!
