Problem: The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. Much higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (1012) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm3. Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average. According to modern understanding, even if all matter could be removed from a volume, it would still not be "empty" due to vacuum fluctuations, dark energy, transiting gamma rays, cosmic rays, neutrinos, and other phenomena in quantum physics. In the electromagnetism in the 19th century, vacuum was thought to be filled with a medium called aether. In modern particle physics, the vacuum state is considered the ground state of matter.
The Vacuum state is considered what?
The answer is the following: the ground state of matter.

Problem: KU football dates from 1890, and has played in the Orange Bowl three times: 1948, 1968, and 2008. They are currently coached by David Beaty, who was hired in 2014. In 2008, under the leadership of Mark Mangino, the #7 Jayhawks emerged victorious in their first BCS bowl game, the FedEx Orange Bowl, with a 2421 victory over the #3 Virginia Tech Hokies. This capstone victory marked the end of the most successful season in school history, in which the Jayhawks went 121 (.923). The team plays at Memorial Stadium, which recently underwent a $31 million renovation to add the Anderson Family Football Complex, adding a football practice facility adjacent to the stadium complete with indoor partial practice field, weight room, and new locker room.
What is the name of the facility that the KU football team plays in?
The answer is the following: Memorial Stadium

Problem: The U.N. speech was well received but the Soviets never acted upon it, due to an overarching concern for the greater stockpiles of nuclear weapons in the U.S. arsenal. Indeed, Eisenhower embarked upon a greater reliance on the use of nuclear weapons, while reducing conventional forces, and with them the overall defense budget, a policy formulated as a result of Project Solarium and expressed in NSC 162/2. This approach became known as the "New Look", and was initiated with defense cuts in late 1953.
What did Eisenhower reduce as he increased nuclear weapons stockpiles?
The answer is the following: conventional forces

Problem: People of Irish descent form the largest single ethnic group in the city, making up 15.8% of the population, followed by Italians, accounting for 8.3% of the population. People of West Indian and Caribbean ancestry are another sizable group, at 6.0%, about half of whom are of Haitian ancestry. Over 27,000 Chinese Americans made their home in Boston city proper in 2013, and the city hosts a growing Chinatown accommodating heavily traveled Chinese-owned bus lines to and from Chinatown, Manhattan. Some neighborhoods, such as Dorchester, have received an influx of people of Vietnamese ancestry in recent decades. Neighborhoods such as Jamaica Plain and Roslindale have experienced a growing number of Dominican Americans. The city and greater area also has a growing immigrant population of South Asians, including the tenth-largest Indian community in the country.
How many Chinese Americans lived in Boston City proper in 2013?
The answer is the following:
Over 27,000
