Answer:
C. marriage
Explanation:
The selection from the Navajo Origin Legend shows the origin of "marriage".
The Navajo Origin Legend is known as a creation myth on how the first husband and wife were created. In the creation myth, it is told that the white ear of corn turned into a man and the yellow ear of corn became a woman. It's said that the wind gave them life. They are the First Man and First Woman. They were later directed to build an enclosure made of brushwood. When it was finished, they entered there as husband and wife.
So, the selection shows the origin of "marriage"
I don't believe that any of these are run-on sentences. This is because they all possess some form of punctuation, which creates a small to moderate oause in the sentence, allowing for the person reading to breathe in between, and preventing a run-on sentence.
It's most likely D, having little value.
Context clues:
Fans want to hear the important parts of the game, so if he is trying to "annoy" them, he must not be saying anything important. So it's "having little value".
