Problem: Dialect:

In the early 20th century, the vast conscription of Italian men from all throughout Italy during World War I is credited with facilitating the diffusion of standard Italian among less educated Italian men, as these men from various regions with various regional languages were forced to communicate with each other in a common tongue while serving in the Italian military. With the eventual spread of the radio and television throughout Italy and the establishment of public education, Italians from all regions were increasingly exposed to standard Italian, while literacy rates among all social classes improved. Today, the majority of Italians are able to speak standard Italian, though many Italians still speak their regional language regularly or as their primary day-to-day language, especially at home with family or when communicating with Italians from the same town or region. However, to some Italians, speaking a regional language, especially in a formal setting or outside of one's region, may carry a stigma or negative connotations associated with being lower class, uneducated, boorish, or overly informal.

During what war did a large number of Italian men first learn standard Italian?
---
A: World War I

Problem: Most of the differences in the revised budget deficit numbers were due to a temporary change of accounting practices by the new government, i.e., recording expenses when military material was ordered rather than received. However, it was the retroactive application of ESA95 methodology (applied since 2000) by Eurostat, that finally raised the reference year (1999) budget deficit to 3.38% of GDP, thus exceeding the 3% limit. This led to claims that Greece (similar claims have been made about other European countries like Italy) had not actually met all five accession criteria, and the common perception that Greece entered the Eurozone through "falsified" deficit numbers.
What were the majority of the differences in the revised budget due to the temporary changing of?
---
Answer: accounting practices

Context and question: In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.
Who sang chopin arrangements on July 7 of the year Chopin was in London?
Answer: Viardot

Question: In 1955 American nuclear arms policy became one aimed primarily at arms control as opposed to disarmament. The failure of negotiations over arms until 1955 was due mainly to the refusal of the Russians to permit any sort of inspections. In talks located in London that year, they expressed a willingness to discuss inspections; the tables were then turned on Eisenhower, when he responded with an unwillingness on the part of the U.S. to permit inspections. In May of that year the Russians agreed to sign a treaty giving independence to Austria, and paved the way for a Geneva summit with the U.S., U.K. and France. At the Geneva Conference Eisenhower presented a proposal called "Open Skies" to facilitate disarmament, which included plans for Russia and the U.S. to provide mutual access to each other's skies for open surveillance of military infrastructure. Russian leader Nikita Khrushchev dismissed the proposal out of hand.
Is there an answer to this question: What was the plan Eisenhower presented at the Geneva Conference called?

Answer: Open Skies

Question: Up until the mid-14th century, Europe had experienced steadily increasing urbanisation. Cities were also decimated by the Black Death, but the role of urban areas as centres of learning, commerce and government ensured continued growth. By 1500, Venice, Milan, Naples, Paris and Constantinople each probably had more than 100,000 inhabitants. Twenty-two other cities were larger than 40,000; most of these were in Italy and the Iberian peninsula, but there were also some in France, the Empire, the Low Countries, plus London in England.
Is there an answer to this question: Which English city had a population greater than 40,000 in 1600?

Answer:
unanswerable
