Problem: Please answer a question about the following article about Pacific War:
In the early hours of 7 December (Hawaiian time), Japan launched a major surprise carrier-based air strike on Pearl Harbor without explicit warning, which crippled the U.S. Pacific Fleet, leaving eight American battleships out of action, 188 American aircraft destroyed, and 2,403 American citizens dead. At the time of the attack, the U.S. was not officially at war anywhere in the world, which means that the people killed or property destroyed at Pearl Harbor by the Japanese attack had a non-combatant status.[nb 11] The Japanese had gambled that the United States, when faced with such a sudden and massive blow, would agree to a negotiated settlement and allow Japan free rein in Asia. This gamble did not pay off. American losses were less serious than initially thought: The American aircraft carriers, which would prove to be more important than battleships, were at sea, and vital naval infrastructure (fuel oil tanks, shipyard facilities, and a power station), submarine base, and signals intelligence units were unscathed. Japan's fallback strategy, relying on a war of attrition to make the U.S. come to terms, was beyond the IJN's capabilities.
What were the most vital American ships at the time of the attack?
A: aircraft carriers
Problem: Please answer a question about the following article about North Carolina:
Confederate troops from all parts of North Carolina served in virtually all the major battles of the Army of Northern Virginia, the Confederacy's most famous army. The largest battle fought in North Carolina was at Bentonville, which was a futile attempt by Confederate General Joseph Johnston to slow Union General William Tecumseh Sherman's advance through the Carolinas in the spring of 1865. In April 1865, after losing the Battle of Morrisville, Johnston surrendered to Sherman at Bennett Place, in what is today Durham. North Carolina's port city of Wilmington was the last Confederate port to fall to the Union, in February 1865, after the Union won the nearby Second Battle of Fort Fisher, its major defense downriver.
What was the name of the largest battle fought in North Carolina?
A: Bentonville
Problem: Please answer a question about the following article about Green:
Green can communicate safety to proceed, as in traffic lights. Green and red were standardized as the colors of international railroad signals in the 19th century. The first traffic light, using green and red gas lamps, was erected in 1868 in front of the Houses of Parliament in London. It exploded the following year, injuring the policeman who operated it. In 1912, the first modern electric traffic lights were put up in Salt Lake City, Utah. Red was chosen largely because of its high visibility, and its association with danger, while green was chosen largely because it could not be mistaken for red. Today green lights universally signal that a system is turned on and working as it should. In many video games, green signifies both health and completed objectives, opposite red.
Where were the first modern electric traffic lights erected in 1912?
A: Salt Lake City, Utah
Problem: Please answer a question about the following article about Iran:
The prolonged Byzantine-Sassanid Wars, most importantly the climactic Byzantine-Sassanid War of 602-628, as well as the social conflict within the Sassanid Empire, opened the way for an Arab invasion to Iran in the 7th century. Initially defeated by the Arab Rashidun Caliphate, Iran came under the rule of the Arab caliphates of Umayyad and Abbasid. The prolonged and gradual process of the Islamization of Iran began following the conquest. Under the new Arab elite of the Rashidun and later the Umayyad caliphates, both converted (mawali) and non-converted (dhimmi) Iranians were discriminated against, being excluded from the government and military, and having to pay a special tax called Jizya. Gunde Shapur, home of the Academy of Gunde Shapur which was the most important medical center of the world at the time, survived after the invasion, but became known as an Islamic institute thereafter.
What academy was the most important medical center of the world at the time and became Islamicized after the Arab invasions?
A:
Academy of Gunde Shapur
