Explain how to locate 15 degrees s, 45 degrees w. then locate that spot on a map or globe . where are you?

The correct answer to this open question is the following.

You can locate 15 degrees S, 45 degrees W, basically in two ways. One, the old-fashion way, using a map that includes using a printed map. There, such as the case of an Atlas, you will find the coordinates. The other option is to use google maps or other GPS services and write the coordinates to locate that spot on a map or globe.

In this case, the location is an area in Brasil, South America.

the answer is "c" im pretty sure.
