Internal conflict is the point at which a character has to decide to admit to themselves what the issue going on in their head is and to take some sort of action on it. For some characters such as Dante (Dante's Inferno), this is dealing with depression and seeing the things that await him in Hell if he commits suicide. For others, it's working an issue that is a part of their past, such as PTSD flashbacks from war.
I'm not entirely sure how to say where in a story this conflict takes place, as it varies from piece to piece. Hopefully, however, this provides some better understanding of the concept.
Answer:
The first one.
"I can't sing very well I can't dance very well"
The answer is C.
We’re talking about what changes can be made to keep players safe from head injuries
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!
