Problem: Please answer a question about the following article about Dissolution of the Soviet Union:
In the first session of the new Congress of People's Deputies, from May 25 to June 9, hardliners retained control but reformers used the legislature as a platform for debate and criticism – which was broadcast live and uncensored. This transfixed the population; nothing like this freewheeling debate had ever been witnessed in the U.S.S.R. On May 29, Yeltsin managed to secure a seat on the Supreme Soviet, and in the summer he formed the first opposition, the Inter-Regional Deputies Group, composed of Russian nationalists and liberals. Composing the final legislative group in the Soviet Union, those elected in 1989 played a vital part in reforms and the eventual breakup of the Soviet Union during the next two years.
Who made up the Inter-Regional Deputies Group?
A: Russian nationalists and liberals.
Problem: Please answer a question about the following article about Palermo:
In 2010, there were 1.2 million people living in the greater Palermo area, 655,875 of which resided in the City boundaries, of whom 47.4% were male and 52.6% were female. People under age 15 totalled 15.6% compared to pensioners who composed 17.2% of the population. This compares with the Italian average of 14.1% people under 15 years and 20.2% pensioners. The average age of a Palermo resident is 40.4 compared to the Italian average of 42.8. In the ten years between 2001 and 2010, the population of Palermo declined by 4.5%, while the population of Italy, as a whole, grew by 6.0%. The reason for Palermo's decline is a population flight to the suburbs, and to Northern Italy. The current birth rate of Palermo is 10.2 births per 1,000 inhabitants compared to the Italian average of 9.3 births.
How many people were living in the Palermo area in 2010?
A: 1.2 million
Problem: Please answer a question about the following article about Glass:
Most common glass contains other ingredients to change its properties. Lead glass or flint glass is more 'brilliant' because the increased refractive index causes noticeably more specular reflection and increased optical dispersion. Adding barium also increases the refractive index. Thorium oxide gives glass a high refractive index and low dispersion and was formerly used in producing high-quality lenses, but due to its radioactivity has been replaced by lanthanum oxide in modern eyeglasses.[citation needed] Iron can be incorporated into glass to absorb infrared energy, for example in heat absorbing filters for movie projectors, while cerium(IV) oxide can be used for glass that absorbs UV wavelengths.
What property of thorium oxide has caused it to no longer be used in eyeglasses?
A: radioactivity
Problem: Please answer a question about the following article about Middle Ages:
Besides the schism, the western church was riven by theological controversies, some of which turned into heresies. John Wycliffe (d. 1384), an English theologian, was condemned as a heretic in 1415 for teaching that the laity should have access to the text of the Bible as well as for holding views on the Eucharist that were contrary to church doctrine. Wycliffe's teachings influenced two of the major heretical movements of the later Middle Ages: Lollardy in England and Hussitism in Bohemia. The Bohemian movement initiated with the teaching of Jan Hus, who was burned at the stake in 1415 after being condemned as a heretic by the Council of Constance. The Hussite church, although the target of a crusade, survived beyond the Middle Ages. Other heresies were manufactured, such as the accusations against the Knights Templar that resulted in their suppression in 1312 and the division of their great wealth between the French King Philip IV (r. 1285–1314) and the Hospitallers.
How did Jan Hus die?
A:
burned at the stake
