Here is a question about this article: The competition is open to any eligible club down to Levels 10 of the English football league system - all 92 professional clubs in the Premier League and Football League (Levels 1 to 4), and several hundred "non-league" teams in Steps 1 to 6 of the National League System (Levels 5 to 10). A record 763 clubs competed in 2011–12. The tournament consists of 12 randomly drawn rounds followed by the semi-finals and the final. Entrants are not seeded, although a system of byes based on league level ensures higher ranked teams enter in later rounds - the minimum number of games needed to win the competition ranges from six to fourteen.
What is the answer to this question: How many games are needed to win?
****
So... six to fourteen

Here is a question about this article: USB 2.0 devices use a special protocol during reset, called chirping, to negotiate the high bandwidth mode with the host/hub. A device that is HS capable first connects as an FS device (D+ pulled high), but upon receiving a USB RESET (both D+ and D− driven LOW by host for 10 to 20 ms) it pulls the D− line high, known as chirp K. This indicates to the host that the device is high bandwidth. If the host/hub is also HS capable, it chirps (returns alternating J and K states on D− and D+ lines) letting the device know that the hub operates at high bandwidth. The device has to receive at least three sets of KJ chirps before it changes to high bandwidth terminations and begins high bandwidth signaling. Because USB 3.0 uses wiring separate and additional to that used by USB 2.0 and USB 1.x, such bandwidth negotiation is not required.
What is the answer to this question: What is the special protocol during a USB 2.0 device reset called?
****
So...
chirping
