Problem: Please answer a question about the following article about Arena Football League:
Following the suspension of the AFL's 2009 season, league officials and owners of af2 (which had played its season as scheduled) began discussing the future of arena football and the two leagues. With its 50.1 percent ownership of af2, the AFL's bankruptcy and dissolution prompted the dissolution of af2 as well. That league was formally considered disbanded on September 8, 2009, when no owner committed his or her team to the league's eleventh season by that deadline. For legal reasons, af2 league officials and owners agreed to form a new legal entity, Arena Football 1 (AF1), with former AFL teams the Arizona Rattlers and Orlando Predators joining the former af2.
On what date was af2 regarded as disbanded?
A: September 8, 2009
Problem: Please answer a question about the following article about American Idol:
In seasons ten and eleven, a further round was added in Las Vegas, where the contestants perform in groups based on a theme, followed by one final solo round to determine the semi-finalists. At the end of this stage of the competition, 24 to 36 contestants are selected to move on to the semi-final stage. In season twelve the Las Vegas round became a Sudden Death round, where the judges had to choose five guys and five girls each night (four nights) to make the top twenty. In season thirteen, a new round called "Hollywood or Home" was added, where if the judges were uncertain about some contestants, those contestants were required to perform soon after landing in Los Angeles, and those who failed to impress were sent back home before they reached Hollywood.
What was the Las Vegas round called in season twelve?
A: Sudden Death
Problem: Please answer a question about the following article about IPod:
Though the iPod was released in 2001, its price and Mac-only compatibility caused sales to be relatively slow until 2004. The iPod line came from Apple's "digital hub" category, when the company began creating software for the growing market of personal digital devices. Digital cameras, camcorders and organizers had well-established mainstream markets, but the company found existing digital music players "big and clunky or small and useless" with user interfaces that were "unbelievably awful," so Apple decided to develop its own. As ordered by CEO Steve Jobs, Apple's hardware engineering chief Jon Rubinstein assembled a team of engineers to design the iPod line, including hardware engineers Tony Fadell and Michael Dhuey, and design engineer Sir Jonathan Ive. Rubinstein had already discovered the Toshiba disk drive when meeting with an Apple supplier in Japan, and purchased the rights to it for Apple, and had also already worked out how the screen, battery, and other key elements would work. The aesthetic was inspired by the 1958 Braun T3 transistor radio designed by Dieter Rams, while the wheel based user interface was prompted by Bang & Olufsen's BeoCom 6000 telephone. The product ("the Walkman of the twenty-first century" ) was developed in less than one year and unveiled on October 23, 2001. Jobs announced it as a Mac-compatible product with a 5 GB hard drive that put "1,000 songs in your pocket."
What other popular music player did Apple compare their new product to?
A: the Walkman
Problem: Please answer a question about the following article about Greece:
By 500 BC, the Persian Empire controlled the Greek city states in Asia Minor and had made territorial gains in the Balkans and Eastern Europe proper as well. Attempts by some of the Greek city-states of Asia Minor to overthrow Persian rule failed, and Persia invaded the states of mainland Greece in 492 BC, but was forced to withdraw after a defeat at the Battle of Marathon in 490 BC. A second invasion by the Persians followed in 480 BC. Despite a heroic resistance at Thermopylae by Spartans and other Greeks led by King Leonidas, and a simultaneous naval engagement at Artemisium,[page needed] Persian forces occupied Athens, which had been evacuated in time, as well as briefly overrunning half of Greece. Following decisive Greek victories in 480 and 479 BC at Salamis, Plataea, and Mycale, the Persians were forced to withdraw for a second time, marking their eventual withdrawal from all of their European territories. Led by Athens and Sparta, the Greek victories in the Greco-Persian Wars are considered a pivotal moment in world history, as the 50 years of peace that followed are known as Golden Age of Athens, the seminal period of ancient Greece that laid many of the foundations of Western civilization.
In 500 BC, Greece was ruled over by who?
A:
Persian Empire
