Answer:
C) One passage provides objective economic data about the river while the others tell the story of two boys adventuring on its waters
Step-by-step explanation:
First passage is from Mary O'Dell's "The Mississippi: Dual Passages" while the other is from Mark Twain's "The Adventures of Tom Sawyer".
Also, we can see that the first excerpt provides some date on the river itself, its economic importance and some brief origin of the river transport.
Second passage is an excerpt from a novel and doesn't deal with the pieces of information regarding river, but rather mentions it briefly for the sole purpose of the story's setting.
