instruction:
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
question:
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.
answer:
small


question:
Which element is mentioned?, Context: Breathing pure O2 in space applications, such as in some modern space suits, or in early spacecraft such as Apollo, causes no damage due to the low total pressures used. In the case of spacesuits, the O2 partial pressure in the breathing gas is, in general, about 30 kPa (1.4 times normal), and the resulting O2 partial pressure in the astronaut's arterial blood is only marginally more than normal sea-level O2 partial pressure (for more information on this, see space suit and arterial blood gas).
answer:
O2


question:
Where did the ships meet under caesar?, Context: After having declined in size following the subjugation of the Mediterranean, the Roman navy underwent short-term upgrading and revitalisation in the late Republic to meet several new demands. Under Caesar, an invasion fleet was assembled in the English Channel to allow the invasion of Britannia; under Pompey, a large fleet was raised in the Mediterranean Sea to clear the sea of Cilician pirates. During the civil war that followed, as many as a thousand ships were either constructed or pressed into service from Greek cities.
answer:

English Channel
