Problem: Arnold Schwarzenegger:

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.

What governmental department contributed a grant to Schwarzenegger's hydrogen fuel project?
---
A: U.S. Department of Energy

Problem: The SI unit of pressure is the pascal (symbol Pa), but vacuum is often measured in torrs, named for Torricelli, an early Italian physicist (16081647). A torr is equal to the displacement of a millimeter of mercury (mmHg) in a manometer with 1 torr equaling 133.3223684 pascals above absolute zero pressure. Vacuum is often also measured on the barometric scale or as a percentage of atmospheric pressure in bars or atmospheres. Low vacuum is often measured in millimeters of mercury (mmHg) or pascals (Pa) below standard atmospheric pressure. "Below atmospheric" means that the absolute pressure is equal to the current atmospheric pressure.
How many pascals does the barometric scale equal?

The fighter aircraft of the USAF are small, fast, and maneuverable military aircraft primarily used for air-to-air combat. Many of these fighters have secondary ground-attack capabilities, and some are dual-roled as fighter-bombers (e.g., the F-16 Fighting Falcon); the term "fighter" is also sometimes used colloquially for dedicated ground-attack aircraft. Other missions include interception of bombers and other fighters, reconnaissance, and patrol. The F-16 is currently used by the USAF Air Demonstration squadron, the Thunderbirds, while a small number of both man-rated and non-man-rated F-4 Phantom II are retained as QF-4 aircraft for use as Full Scale Aerial Targets (FSAT) or as part of the USAF Heritage Flight program. These extant QF-4 aircraft are being replaced in the FSAT role by early model F-16 aircraft converted to QF-16 configuration. The USAF has 2,025 fighters in service as of September 2012.
What is the name of a type of dual purpose fighter-bomber aircraft used by the US Air Force?
A: F-16 Fighting Falcon

Context and question: Tucson was probably first visited by Paleo-Indians, known to have been in southern Arizona about 12,000 years ago. Recent archaeological excavations near the Santa Cruz River have located a village site dating from 2100 BC.[citation needed] The floodplain of the Santa Cruz River was extensively farmed during the Early Agricultural period, circa 1200 BC to AD 150. These people constructed irrigation canals and grew corn, beans, and other crops while gathering wild plants and hunting. The Early Ceramic period occupation of Tucson saw the first extensive use of pottery vessels for cooking and storage. The groups designated as the Hohokam lived in the area from AD 600 to 1450 and are known for their vast irrigation canal systems and their red-on-brown pottery.[citation needed]
Who were probably the first group of people in Tuscan?
Answer: Paleo-Indians

Question: To restrict the meaning of (architectural) formalism to art for art's sake is not only reactionary; it can also be a purposeless quest for perfection or originality which degrades form into a mere instrumentality".
Is there an answer to this question: What ends up being maximized in quality by this quest?

U.S. President Barack Obama has rarely used the term, but in his inaugural address on 20 January 2009, he stated "Our nation is at war, against a far-reaching network of violence and hatred." In March 2009 the Defense Department officially changed the name of operations from "Global War on Terror" to "Overseas Contingency Operation" (OCO). In March 2009, the Obama administration requested that Pentagon staff members avoid use of the term, instead using "Overseas Contingency Operation". Basic objectives of the Bush administration "war on terror", such as targeting al Qaeda and building international counterterrorism alliances, remain in place. In December 2012, Jeh Johnson, the General Counsel of the Department of Defense, stated that the military fight will be replaced by a law enforcement operation when speaking at Oxford University, predicting that al Qaeda will be so weakened to be ineffective, and has been "effectively destroyed", and thus the conflict will not be an armed conflict under international law. In May 2013, Obama stated that the goal is "to dismantle specific networks of violent extremists that threaten America"; which coincided with the U.S. Office of Management and Budget having changed the wording from "Overseas Contingency Operations" to "Countering Violent Extremism" in 2010.
Who defined the goal in a speech in May of 2012?
A:
