The only example of internal conflict among these is Kevin wants to take Katie to a dance, but his best friend Jason has already told Lauren and Ashley that he and Kevin would take them.
The other examples are all external conflicts.
A is the correct answer. Let me explain:
The beginning of sentence "5" starts abruptly with, "I was walking by the dirt lot." If there was a transition into this statement, such as, "Later, when I was walking by the dirt lot..." it would flow better and make room for good writing.
In "Song of Myself", Walt Whitman is writing about individuality and self reliance, as we can see from the first line of the poem: "I CELEBRATE myself, and sing myself", This poem emphasizes the "Self", it can be interpreted as a "cosmic self" it can even be read as an individuality that is collective: "And what I assume you shall assume,
/ For every atom belonging to me as good belongs to you".
