Input: Vacuum
QED vacuum has interesting and complex properties. In QED vacuum, the electric and magnetic fields have zero average values, but their variances are not zero. As a result, QED vacuum contains vacuum fluctuations (virtual particles that hop into and out of existence), and a finite energy called vacuum energy. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory. Some experimentally verified effects of vacuum fluctuations include spontaneous emission and the Lamb shift. Coulomb's law and the electric potential in vacuum near an electric charge are modified.

When are electric and magnetic fields with zero average values, but their variances are not at zero?
Output: In QED vacuum


Input: Article: On December 3, 2013, Adidas officially confirmed a new shoe collaboration deal with West. After months of anticipation and rumors, West confirmed the release of the Adidas Yeezy Boosts with a Twitter announcement directing fans to the domain yeezy.supply.

Article: Victoria was pleased when Gladstone resigned in 1885 after his budget was defeated. She thought his government was "the worst I have ever had", and blamed him for the death of General Gordon at Khartoum. Gladstone was replaced by Lord Salisbury. Salisbury's government only lasted a few months, however, and Victoria was forced to recall Gladstone, whom she referred to as a "half crazy & really in many ways ridiculous old man". Gladstone attempted to pass a bill granting Ireland home rule, but to Victoria's glee it was defeated. In the ensuing election, Gladstone's party lost to Salisbury's and the government switched hands again.

Question: What year did Gladstone resign?
Ans: 1885


Here is a question about this article: The 9/11 Commission's final report on July 22, 2004 stated that the FBI and Central Intelligence Agency (CIA) were both partially to blame for not pursuing intelligence reports that could have prevented the September 11, 2001 attacks. In its most damning assessment, the report concluded that the country had "not been well served" by either agency and listed numerous recommendations for changes within the FBI. While the FBI has acceded to most of the recommendations, including oversight by the new Director of National Intelligence, some former members of the 9/11 Commission publicly criticized the FBI in October 2005, claiming it was resisting any meaningful changes.
What is the answer to this question: What agencies were to blame for 9/11?
****
So... FBI and Central Intelligence Agency


The problem: Answer a question about this article:
In 1663 at the Archbishop of Canterbury's residence, Lambeth Palace, a Gothic hammerbeam roof was built to replace that destroyed when the building was sacked during the English Civil War. Also in the late 17th century, some discrete Gothic details appeared on new construction at Oxford University and Cambridge University, notably on Tom Tower at Christ Church, Oxford, by Christopher Wren. It is not easy to decide whether these instances were Gothic survival or early appearances of Gothic revival.
In what century were distinct Gothic details used on new construction at Oxford and Cambridge?
****
The answer: the late 17th century
