Final answer:
Advancements in technology have decreased distance decay by enabling faster travel and communication across long distances.
Step-by-step explanation:
Distance decay refers to the decrease in interaction between two locations as the distance between them increases. Advancements in technology such as transportation and communication have significantly reduced the impact of distance decay. For example, the invention of airplanes and the internet have made it easier and faster for people to travel and communicate across long distances. This has led to a decrease in distance decay as people are now able to interact and connect with others regardless of their physical distance.
