Problem: Southeast Asia:

Homo sapiens reached the region by around 45,000 years ago, having moved eastwards from the Indian subcontinent. Homo floresiensis also lived in the area up until 12,000 years ago, when they became extinct. Austronesian people, who form the majority of the modern population in Indonesia, Malaysia, Brunei, East Timor, and the Philippines, may have migrated to Southeast Asia from Taiwan. They arrived in Indonesia around 2000 BC,and as they spread through the archipelago, they often settled along coastal areas and confined indigenous peoples such as Negritos of the Philippines or Papuans of New Guinea to inland regions.

How long ago did the Homo floresiensis live before they became extinct?

A: 12,000 years ago


Problem: Many[who?] expected BSkyB to make a bid to show some of the remaining FA Cup games for the remainder of the 2009–10 season which would include a semi-final and shared rights to the final. ESPN took over the package Setanta held for the FA Cup from the 2010–11 season. The 2011 final was also shown live on Sky 3D in addition to ESPN (who provided the 3D coverage for Sky 3D) and ITV. Following the sale of ESPN's UK and Ireland channels to BT, ESPN's rights package transferred to BT Sport from the 2013–14 season.
Who was expected to make a bid for the 2010-11 season?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Starting in 1940 (18 months before Pearl Harbor), the nation mobilized, giving high priority to air power. American involvement in World War II in 1940–41 was limited to providing war material and financial support to Britain, the Soviet Union, and the Republic of China. The U.S. entered officially on 8 December 1941 following the Japanese attack on Pearl Harbor, Hawaii. Japanese forces soon seized American, Dutch, and British possessions across the Pacific and Southeast Asia, except for Australia, which became a main American forward base along with Hawaii.
 When did the US officially enter World War I?
A: unanswerable


Context and question: When Nintendo released the NES in the US, the design styling was deliberately different from that of other game consoles. Nintendo wanted to distinguish its product from those of competitors and to avoid the generally poor reputation that game consoles had acquired following the video game crash of 1983. One result of this philosophy was to disguise the cartridge slot design as a front-loading zero insertion force (ZIF) cartridge socket, designed to resemble the front-loading mechanism of a VCR. The newly designed connector worked quite well when both the connector and the cartridges were clean and the pins on the connector were new. Unfortunately, the ZIF connector was not truly zero insertion force. When a user inserted the cartridge into the NES, the force of pressing the cartridge down and into place bent the contact pins slightly, as well as pressing the cartridge’s ROM board back into the cartridge itself. Frequent insertion and removal of cartridges caused the pins to wear out from repeated usage over the years and the ZIF design proved more prone to interference by dirt and dust than an industry-standard card edge connector. These design issues were not alleviated by Nintendo’s choice of materials; the console slot nickel connector springs would wear due to design and the game cartridge copper connectors were also prone to tarnishing. Many players would try to alleviate issues in the game caused by this corrosion by blowing into the cartridges, then reinserting them, which actually hurt the copper connectors by speeding up the tarnishing.
 What material didn't comprise the game cartridge connectors?
Answer: unanswerable


Question: Its main body is solid sterling silver and silver gilt, while its plinth is made of malachite, a semi-precious stone. The plinth has a silver band around its circumference, upon which the names of the title-winning clubs are listed. Malachite's green colour is also representative of the green field of play. The design of the trophy is based on the heraldry of Three Lions that is associated with English football. Two of the lions are found above the handles on either side of the trophy – the third is symbolised by the captain of the title winning team as he raises the trophy, and its gold crown, above his head at the end of the season. The ribbons that drape the handles are presented in the team colours of the league champions that year.
Is there an answer to this question: What has a golden band around its circumference?

Answer: unanswerable


Question: The onset of symptoms in myocardial infarction (MI) is usually gradual, over several minutes, and rarely instantaneous. Chest pain is the most common symptom of acute MI and is often described as a sensation of tightness, pressure, or squeezing. Chest pain due to ischemia (a lack of blood and hence oxygen supply) of the heart muscle is termed angina pectoris. Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, back, and upper abdomen, where it may mimic heartburn. Levine's sign, in which a person localizes the chest pain by clenching their fists over their sternum, has classically been thought to be predictive of cardiac chest pain, although a prospective observational study showed it had a poor positive predictive value.
Is there an answer to this question: What is a good way to predict a heart attack?
