Q: How vast is the area that GRTC serves?, Context: Local transit and paratransit bus service in Richmond, Henrico, and Chesterfield counties is provided by the Greater Richmond Transit Company (GRTC). The GRTC, however, serves only small parts of the suburban counties. The far West End (Innsbrook and Short Pump) and almost all of Chesterfield County have no public transportation despite dense housing, retail, and office development. According to a 2008 GRTC operations analysis report, a majority of GRTC riders utilize their services because they do not have an available alternative such as a private vehicle.

A: small

Q: Which happened first, San Diego became connected to a railroad, or Horton promoted moving to the bayside?, Context: The original town of San Diego was located at the foot of Presidio Hill, in the area which is now Old Town San Diego State Historic Park. The location was not ideal, being several miles away from navigable water. In 1850, William Heath Davis promoted a new development by the Bay shore called "New San Diego", several miles south of the original settlement; however, for several decades the new development consisted only a few houses, a pier and an Army depot. In the late 1860s, Alonzo Horton promoted a move to the bayside area, which he called "New Town" and which became Downtown San Diego. Horton promoted the area heavily, and people and businesses began to relocate to New Town because of its location on San Diego Bay convenient to shipping. New Town soon eclipsed the original settlement, known to this day as Old Town, and became the economic and governmental heart of the city. Still, San Diego remained a relative backwater town until the arrival of a railroad connection in 1878.

A:
Horton promoted a move to the bayside
