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:
Small pneumatic __ can hold only one person., Context: A residential elevator is often permitted to be of lower cost and complexity than full commercial elevators. They may have unique design characteristics suited for home furnishings, such as hinged wooden shaft-access doors rather than the typical metal sliding doors of commercial elevators. Construction may be less robust than in commercial designs with shorter maintenance periods, but safety systems such as locks on shaft access doors, fall arrestors, and emergency phones must still be present in the event of malfunction.
answer:
elevators

question:
Who was the current overlord?, Context: The TSFSR existed from 1922 to 1936, when it was divided up into three separate entities (Armenian SSR, Azerbaijan SSR, and Georgian SSR). Armenians enjoyed a period of relative stability under Soviet rule. They received medicine, food, and other provisions from Moscow, and communist rule proved to be a soothing balm in contrast to the turbulent final years of the Ottoman Empire. The situation was difficult for the church, which struggled under Soviet rule. After the death of Vladimir Lenin, Joseph Stalin took the reins of power and began an era of renewed fear and terror for Armenians.
answer:
Soviet rule

question:
What is the Rapid Transit System?, Context: Richmond is a major hub for intercity bus company Greyhound Lines, with its terminal at 2910 N Boulevard. Multiple runs per day connect directly with Washington, D.C., New York, Raleigh, and elsewhere. Direct trips to New York take approximately 7.5 hours. Discount carrier Megabus also provides curbside service from outside of Main Street Station, with fares starting at $1. Direct service is available to Washington, D.C., Hampton Roads, Charlotte, Raleigh, Baltimore, and Philadelphia. Most other connections to Megabus served cites, such as New York, can be made from Washington, D.C. Richmond, and the surrounding metropolitan area, was granted[when?] a roughly $25 million grant from the U.S. Department of Transportation to support a newly proposed Rapid Transit System, which would run along Broad Street from Willow Lawn to Rocketts Landing, in the first phase of an improved public transportation hub for the region.
answer:
public transportation
