Video games limit children’s physical activity and inhibit their natural ability to play and imagine.

Hi there!

The answer would be D. Video games limit children’s physical activity and inhibit their natural ability to play and imagine.

All other choices are facts, and viewpoints aren’t necessarily facts, their just a way someone sees something or a certain situation. In the last statement it says how video games limit children’s physical activity which is against video games. Where the opposite of that sentence could be “video games help with hand-eye coordination”.

Hope this helps !
