Please answer this: Extract the answer to the question from the following context. Question: QED stands for what? Context: In quantum mechanics and quantum field theory, the vacuum is defined as the state (that is, the solution to the equations of the theory) with the lowest possible energy (the ground state of the Hilbert space). In quantum electrodynamics this vacuum is referred to as 'QED vacuum' to distinguish it from the vacuum of quantum chromodynamics, denoted as QCD vacuum. QED vacuum is a state with no matter particles (hence the name), and also no photons. As described above, this state is impossible to achieve experimentally. (Even if every matter particle could somehow be removed from a volume, it would be impossible to eliminate all the blackbody photons.) Nonetheless, it provides a good model for realizable vacuum, and agrees with a number of experimental observations as described next.

Problem: Extract the answer to the question from the following context. Question: What proceeded Phantom Hourglass? Context: In four months, Aonuma's team managed to present realistic horseback riding,[l] which Nintendo later revealed to the public with a trailer at Electronic Entertainment Expo 2004. The game was scheduled to be released the next year, and was no longer a follow-up to The Wind Waker; a true sequel to it was released for the Nintendo DS in 2007, in the form of Phantom Hourglass. Miyamoto explained in interviews that the graphical style was chosen to satisfy demand, and that it better fit the theme of an older incarnation of Link. The game runs on a modified The Wind Waker engine.

A: The Wind Waker
Problem: Given the question: Extract the answer to the question from the following context. Question: Which man is listed first? Context: Eisenhower's main goals in office were to keep pressure on the Soviet Union and reduce federal deficits. In the first year of his presidency, he threatened the use of nuclear weapons in an effort to conclude the Korean War; his New Look policy of nuclear deterrence prioritized inexpensive nuclear weapons while reducing funding for conventional military forces. He ordered coups in Iran and Guatemala. Eisenhower refused to give major aid to help France in Vietnam. He gave strong financial support to the new nation of South Vietnam. Congress agreed to his request in 1955 for the Formosa Resolution, which obliged the U.S. to militarily support the pro-Western Republic of China in Taiwan and continue the isolation of the People's Republic of China.

Eisenhower
input question: Extract the answer to the question from the following context. Question: name a bike organization in the city Context: Santa Monica has a bike action plan and recently launched a Bicycle sharing system in November 2015. The city is traversed by the Marvin Braude Bike Trail. Santa Monica has received the Bicycle Friendly Community Award (Bronze in 2009, Silver in 2013) by the League of American Bicyclists. Local bicycle advocacy organizations include Santa Monica Spoke, a local chapter of the Los Angeles County Bicycle Coalition. Santa Monica is thought to be one of the leaders for bicycle infrastructure and programming in Los Angeles County.[citation needed]???
output answer: Santa Monica Spoke
Extract the answer to the question from the following context. Question: What kind of information does the human mind have limitations with? Context: Arthur M. Diamond argues Hayek's problems arise when he goes beyond claims that can be evaluated within economic science. Diamond argued that: "The human mind, Hayek says, is not just limited in its ability to synthesize a vast array of concrete facts, it is also limited in its ability to give a deductively sound ground to ethics. Here is where the tension develops, for he also wants to give a reasoned moral defense of the free market. He is an intellectual skeptic who wants to give political philosophy a secure intellectual foundation. It is thus not too surprising that what results is confused and contradictory."

Answer: vast array of concrete facts, it is also limited in its ability to give a deductively sound ground to ethics
Q: Extract the answer to the question from the following context. Question: What sport is the text about? Context: Penalties never result in a score for the offence. For example, a point-of-foul infraction committed by the defence in their end zone is not ruled a touchdown, but instead advances the ball to the one-yard line with an automatic first down. For a distance penalty, if the yardage is greater than half the distance to the goal line, then the ball is advanced half the distance to the goal line, though only up to the one-yard line (unlike American football, in Canadian football no scrimmage may start inside either one-yard line). If the original penalty yardage would have resulted in a first down or moving the ball past the goal line, a first down is awarded.
A:
Canadian football
