Input: Article: Monastic reform inspired change in the secular church. The ideals that it was based upon were brought to the papacy by Pope Leo IX (pope 1049–1054), and provided the ideology of the clerical independence that led to the Investiture Controversy in the late 11th century. This involved Pope Gregory VII (pope 1073–85) and Emperor Henry IV, who initially clashed over episcopal appointments, a dispute that turned into a battle over the ideas of investiture, clerical marriage, and simony. The emperor saw the protection of the Church as one of his responsibilities as well as wanting to preserve the right to appoint his own choices as bishops within his lands, but the papacy insisted on the Church's independence from secular lords. These issues remained unresolved after the compromise of 1122 known as the Concordat of Worms. The dispute represents a significant stage in the creation of a papal monarchy separate from and equal to lay authorities. It also had the permanent consequence of empowering German princes at the expense of the German emperors.

Now answer this question: What secular rulers did the Concordat of Worms increase the power of?

Output: German princes

Here is a question about this article: In 1935, Reza Shah requested the international community to refer to the country by its native name, Iran. As the New York Times explained at the time, "At the suggestion of the Persian Legation in Berlin, the Tehran government, on the Persian New Year, Nowruz, March 21, 1935, substituted Iran for Persia as the official name of the country." Opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably. Today, both Persia and Iran are used in cultural contexts; although, Iran is the name used officially in political contexts.
What is the answer to this question: Which name is officially used politically?
****
So... Iran


The problem: Answer a question about this article:
During the later stages of World War II, the entire Cold War, and to a lesser extent afterwards, uranium-235 has been used as the fissile explosive material to produce nuclear weapons. Initially, two major types of fission bombs were built: a relatively simple device that uses uranium-235 and a more complicated mechanism that uses plutonium-239 derived from uranium-238. Later, a much more complicated and far more powerful type of fission/fusion bomb (thermonuclear weapon) was built, that uses a plutonium-based device to cause a mixture of tritium and deuterium to undergo nuclear fusion. Such bombs are jacketed in a non-fissile (unenriched) uranium case, and they derive more than half their power from the fission of this material by fast neutrons from the nuclear fusion process.
During what war was uranium-235 first used to create nuclear weapons?
****
The answer: World War II

Question: Read this and answer the question

In the colonial years, while conditions were more fluid, white women, indentured servant or free, and African men, servant, slave or free, made unions. Because the women were free, their mixed-race children were born free; they and their descendants formed most of the families of free people of color during the colonial period in Virginia. The scholar Paul Heinegg found that eighty percent of the free people of color in North Carolina in censuses from 1790–1810 could be traced to families free in Virginia in colonial years.

What censuses did he study?
Answer:
from 1790–1810
