Answer A is incorrect because the time head injuries were first discovered is irrelevant to keeping kids safe.
Answer B is incorrect because you’re asking a yes or no question for a difficult and elaborate topic.
Answer D is incorrect because we’re currently examining why head injuries are dangerous and what can be done to prevent them.
Answer E is incorrect because this is just speaking of the faults of the human skull. This doesn’t help truly solve the changes that can be made.
I hope this helps!
