Problem: New York's high rate of public transit use, over 200,000 daily cyclists as of 2014, and many pedestrian commuters make it the most energy-efficient major city in the United States. Walk and bicycle modes of travel account for 21% of all modes for trips in the city; nationally the rate for metro regions is about 8%. In both its 2011 and 2015 rankings, Walk Score named New York City the most walkable large city in the United States. Citibank sponsored the introduction of 10,000 public bicycles for the city's bike-share project in the summer of 2013. Research conducted by Quinnipiac University showed that a majority of New Yorkers support the initiative. New York City's numerical "in-season cycling indicator" of bicycling in the city hit an all-time high in 2013.
What company paid for 10,000 bikes for the city's bicycle sharing program?
---
Answer: Citibank


Problem: Constantius, renewing his previous policies favoring the Arians, banished Athanasius from Alexandria once again. This was followed, in 356, by an attempt to arrest Athanasius during a vigil service. Athanasius fled to Upper Egypt, where he stayed in several monasteries and other houses. During this period, Athanasius completed his work Four Orations against the Arians and defended his own recent conduct in the Apology to Constantius and Apology for His Flight. Constantius's persistence in his opposition to Athanasius, combined with reports Athanasius received about the persecution of non-Arians by the new Arian bishop George of Laodicea, prompted Athanasius to write his more emotional History of the Arians, in which he described Constantius as a precursor of the Antichrist.
 Where did Athanasius flee to before this attempt?

Answer: unanswerable


Problem: 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.
What safety mechanisms are still required, despite lower design costs?
---
Answer:
locks on shaft access doors, fall arrestors, and emergency phones
