Problem
There are 
coins placed flat on a table according to the figure. What is the order of the coins from top to bottom?
![[asy] size(100); defaultpen(linewidth(.8pt)+fontsize(8pt)); draw(arc((0,1), 1.2, 25, 214)); draw(arc((.951,.309), 1.2, 0, 360)); draw(arc((.588,-.809), 1.2, 132, 370)); draw(arc((-.588,-.809), 1.2, 75, 300)); draw(arc((-.951,.309), 1.2, 96, 228)); label("$A$",(0,1),NW); label("$B$",(-1.1,.309),NW); label("$C$",(.951,.309),E); label("$D$",(-.588,-.809),W); label("$E$",(.588,-.809),S); [/asy]](http://latex.artofproblemsolving.com/b/f/5/bf5741398e1d7e23c76474c5b6c6c4148784f554.png)
Solution
By careful inspection and common sense, the answer is 
.
Solution
Note that this image is quite similar to a topological map. This means that the coin that appears closest to us is at the top and the coin that appears farthest from us is at the bottom. Therefore, the answer is E.
