Problem: Raleigh, North Carolina:

After the Civil War began, Governor Zebulon Baird Vance ordered the construction of breastworks around the city as protection from Union troops. During General Sherman's Carolinas Campaign, Raleigh was captured by Union cavalry under the command of General Hugh Judson Kilpatrick on April 13, 1865. As the Confederate cavalry retreated west, the Union soldiers followed, leading to the nearby Battle of Morrisville. The city was spared significant destruction during the War, but due to the economic problems of the post-war period and Reconstruction, with a state economy based on agriculture, it grew little over the next several decades.

Why did the city not grow during the Civil War?

A: a state economy based on agriculture,

Problem: The main representatives of the new style, often referred to as ars nova as opposed to the ars antiqua, were the composers Philippe de Vitry and Guillaume de Machaut. In Italy, where the Provencal troubadours had also found refuge, the corresponding period goes under the name of trecento, and the leading composers were Giovanni da Cascia, Jacopo da Bologna and Francesco Landini. Prominent reformer of Orthodox Church music from the first half of 14th century was John Kukuzelis; he also introduced a system of notation widely used in the Balkans in the following centuries.
Kukuzelis kept the music of which religion?

Context and question: The strongest contribution of the French Academies to the public sphere comes from the concours academiques (roughly translated as 'academic contests') they sponsored throughout France. These academic contests were perhaps the most public of any institution during the Enlightenment. The practice of contests dated back to the Middle Ages, and was revived in the mid-17th century. The subject matter had previously been generally religious and/or monarchical, featuring essays, poetry, and painting. By roughly 1725, however, this subject matter had radically expanded and diversified, including "royal propaganda, philosophical battles, and critical ruminations on the social and political institutions of the Old Regime." Topics of public controversy were also discussed such as the theories of Newton and Descartes, the slave trade, women's education, and justice in France.
Which topics of public controversy became more widely discussed around 1725?
Answer: theories of Newton and Descartes, the slave trade, women's education, and justice

Question: 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.
Is there an answer to this question: By how much did the budget deficit of Greece exceed the 3% limit in the reference year of 1999?

Answer: .38%
