Task: Question Answering
Input (English): Background Paragraph: Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales' activity space, their interactions begin to decrease.

With the advent of faster travel, distance has less effect than it did in the past, except where places previously connected by now-abandoned railways, for example, have fallen off the beaten path. Advances in communications technology, such as telegraphs, telephones, broadcasting, and internet, have further decreased the effects of distance.[1]. 
Story: Wade county was situated to the east of Gray county. Due to a favorable landscape, Wade county built more roads and railways. 
Question: Which county would have a less intertwined activity space between locales?
Output (English): Gray.
