Maybe efficient, you didn't put the passage
Well, it depends on how you write. As you may know,a external conflict is a conflict occurring outside, like tornado or fires. A internal conflict is a conflict occurring inside like emotions. You could write about a man surviving on a island, balancing the external conflict (weather, hunger, etc) while still maintaining the emotional conflicts (misses family, difficult to kill animals).
Assuming this is referring to the same options as the previous post, the correct answer would be " she feels as though poetry is a natural extension of the human mind."
