This graphic would be considered a credible source for an essay on which topic?
a) a history of rivers in africa
b) a history of reptiles in africa
c) a history of small villages in africa
d) the history of the bonobo ape in africa

The answer is D. You can assume this because the picture includes an ape, and the subject D is regarding an ape. Or you can find this answer by excluding what it can't be. Can't be A because no rivers are outlined/highlighted in the picture, can't be B because an ape is a mammal not a reptile, and can't be C because again the picture doesn't correspond with villages.
