<span>A) It shifts from first person point of view to third person point of view with the sentence: "That was the last sun that shone on Black Hawk."
The use of "I", "we", and "our" through the first part of the paragraph is what makes it first person point of view. When it switches at this sentence, the pronouns shift to "he", which is what makes it third person point of view. </span>
I would say it is metaphor
Absolute value is the distance away from 0, no matter if the number is negative or positive
Example: 2 numbers with the absolute value of 3
|3| and |-3| both have the absolute value of 3.
So for your question, with an absolute value for 16, and you're looking for a number greater than 13, the answer would be:
16 or |16|
Hope this helps :)
