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

Input: Consider Input: What is a computer program sometimes sitting idle until?, Context: Seemingly, multitasking would cause a computer that is switching between several programs to run more slowly, in direct proportion to the number of programs it is running, but most programs spend much of their time waiting for slow input/output devices to complete their tasks. If a program is waiting for the user to click on the mouse or press a key on the keyboard, then it will not take a "time slice" until the event it is waiting for has occurred. This frees up time for other programs to execute so that many programs may be run simultaneously without unacceptable speed loss.

Output: for the user to click on the mouse or press a key


Input: Consider Input: When did large scale production of such vehicles begin?, Context: The Hummers that Schwarzenegger bought 1992 are so large – each weighs 6,300 lb (2,900 kg) and is 7 feet (2.1 m) wide – that they are classified as large trucks, and U.S. fuel economy regulations do not apply to them. During the gubernatorial recall campaign he announced that he would convert one of his Hummers to burn hydrogen. The conversion was reported to have cost about US$21,000. After the election, he signed an executive order to jump-start the building of hydrogen refueling plants called the California Hydrogen Highway Network, and gained a U.S. Department of Energy grant to help pay for its projected US$91,000,000 cost. California took delivery of the first H2H (Hydrogen Hummer) in October 2004.

Output: After the election


Input: Consider Input: Which occurred first, the creation of the Banco de Valencia or the urban expansion of the Valencia?, Context: During the 20th century Valencia remained the third most populous city of Spain as its population tripled, rising from 213,550 inhabitants in 1900 to 739,014 in 2000. Valencia was also third in industrial and economic development; notable milestones include urban expansion of the city in the latter 1800s, the creation of the Banco de Valencia in 1900, construction of the Central and Columbus markets, and the construction of the Gare du Nord railway station, completed in 1921. The new century was marked in Valencia with a major event, the Valencian regional exhibition of 1909 (La Exposición Regional Valenciana de 1909), which emulated the national and universal expositions held in other cities. This production was promoted by the Ateneo Mercantil de Valencia (Mercantile Athenaeum of Valencia), especially by its chairman, Tomás Trénor y Palavicino, and had the support of the Government and the Crown; it was officially inaugurated by King Alfonso XIII himself.


Output: urban expansion
