Question

when you ask for directions to a post office, you are asking about

a. cartography
b. location
c. gps
d. place

Explanation:

When asking for directions to a post - office, the key element is where the post - office is situated. "Location" specifically refers to the position or place where something is. Cartography is the study and practice of making maps. GPS is a technology for determining location. "Place" is a more general term that can refer to a particular area or locality but is not as directly related to the act of asking for directions (which is about the specific position - location) as "location".

Answer:

B. location
