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

[EX Q]: 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.
[EX A]: After the election

[EX Q]: What needs consistency?, Context: The simplest valve gears give events of fixed length during the engine cycle and often make the engine rotate in only one direction. Most however have a reversing mechanism which additionally can provide means for saving steam as speed and momentum are gained by gradually "shortening the cutoff" or rather, shortening the admission event; this in turn proportionately lengthens the expansion period. However, as one and the same valve usually controls both steam flows, a short cutoff at admission adversely affects the exhaust and compression periods which should ideally always be kept fairly constant; if the exhaust event is too brief, the totality of the exhaust steam cannot evacuate the cylinder, choking it and giving excessive compression ("kick back").[citation needed]
[EX A]: exhaust and compression periods

[EX Q]: what musical act is mentioned last?, Context: The city also has several smaller music venues, including the Brook, The Talking Heads, The Soul Cellar, The Joiners and Turner Sims, as well as smaller "club circuit" venues like Hampton's and Lennon's, and a number of public houses including the Platform tavern, the Dolphin, the Blue Keys and many others. The Joiners has played host to such acts as Oasis, Radiohead, Green Day, Suede, PJ Harvey, the Manic Street Preachers, Coldplay, the Verve, the Libertines and Franz Ferdinand, while Hampton's and Lennon's have hosted early appearances by Kate Nash, Scouting for Girls and Band of Skulls.
