Explanation:
An external conflict refers to a struggle or problem that occurs between a character and an aoutside force. An oustside force means something that is out of his/her body. Most of times this conflict is between the main character and another character, the natural world, or the society.
It's opposite is the internal conflict in which the character struggles with himself, with his internal emotions and weaknesses.
In this case the conflict is between Connor and Teresa, they are both trying make someone ride with them. Â
