Answer and Explanation:
D is the answer.
Since the author's audience is 4th graders, the paper needs to sound entertaining to the children. Saying that something is awesome, and that the city is built at the foot (bottom) of a weird mountain can attract the attention of the young ones' minds.
A isn't correct because, although it is true, it isn't going to bring the attention of the 4th graders.
B isn't correct because, to the 4th graders, it sounds like it would be boring, since you don't start off with anything cool, and just say a name and a city.
C isn't correct either, since the kids don't want to be referred to as kids, and they would probably choose not to want to know about it.
