Problem: Alfred North Whitehead:

Whitehead was unimpressed by this objection. In the notes of one his students for a 1927 class, Whitehead was quoted as saying: "Every scientific man in order to preserve his reputation has to say he dislikes metaphysics. What he means is he dislikes having his metaphysics criticized." In Whitehead's view, scientists and philosophers make metaphysical assumptions about how the universe works all the time, but such assumptions are not easily seen precisely because they remain unexamined and unquestioned. While Whitehead acknowledged that "philosophers can never hope finally to formulate these metaphysical first principles," he argued that people need to continually re-imagine their basic assumptions about how the universe works if philosophy and science are to make any real progress, even if that progress remains permanently asymptotic. For this reason Whitehead regarded metaphysical investigations as essential to both good science and good philosophy.

 What was Whitehead's opinion of nonmetaphysical investigations?

A: unanswerable


Problem: Missionary efforts to Scandinavia during the 9th and 10th centuries helped strengthen the growth of kingdoms such as Sweden, Denmark, and Norway, which gained power and territory. Some kings converted to Christianity, although not all by 1000. Scandinavians also expanded and colonised throughout Europe. Besides the settlements in Ireland, England, and Normandy, further settlement took place in what became Russia and in Iceland. Swedish traders and raiders ranged down the rivers of the Russian steppe, and even attempted to seize Constantinople in 860 and 907. Christian Spain, initially driven into a small section of the peninsula in the north, expanded slowly south during the 9th and 10th centuries, establishing the kingdoms of Asturias and León.
Along with the kingdom of León, what Spanish kingdom was established during this period?
---
Answer: Asturias


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
After the incorporation of these states to the United States in the first half of the 19th century, the Spanish language was later reinforced in the country by the acquisition of Puerto Rico in 1898. Later waves of emigration from Mexico, Cuba, El Salvador and elsewhere in Hispanic America to the United States beginning in the second half of the 19th century to the present-day have strengthened the role of the Spanish language in the country. Today, Hispanics are one of the fastest growing demographics in the United States, thus increasing the use and importance of American Spanish in the United States.
Who increases the use and importance of American English in the United States?
A: unanswerable


Context and question: After centuries of Danish, Swedish and German rule the native Estonians started to yearn for independence during the period of national awakening while being governed by the Russian Empire. Established on 24 February 1918, the Republic of Estonia came into existence towards the end of World War I. During World War II, Estonia was then occupied by the Soviet Union in 1940, then Nazi Germany a year later and again in 1944 establishing the Estonian Soviet Socialist Republic. In 1988, during the Singing Revolution, the Estonian SSR issued the Estonian Sovereignty Declaration to defy against the illegal Soviet rule. Estonia then restored its independence during the 1991 coup by the Soviets on the night of 20 August 1991.
What war ended as Estonia was born?
Answer: World War I


Question: But although it meets the definition of outer space, the atmospheric density within the first few hundred kilometers above the Kármán line is still sufficient to produce significant drag on satellites. Most artificial satellites operate in this region called low Earth orbit and must fire their engines every few days to maintain orbit.[citation needed] The drag here is low enough that it could theoretically be overcome by radiation pressure on solar sails, a proposed propulsion system for interplanetary travel.[citation needed] Planets are too massive for their trajectories to be significantly affected by these forces, although their atmospheres are eroded by the solar winds.
Is there an answer to this question: What are satellites too large for their engines to be affected by?

Answer: unanswerable


Question: In March 2005, the Security Council formally referred the situation in Darfur to the Prosecutor of the International Criminal Court, taking into account the Commission report but without mentioning any specific crimes. Two permanent members of the Security Council, the United States and China, abstained from the vote on the referral resolution. As of his fourth report to the Security Council, the Prosecutor has found "reasonable grounds to believe that the individuals identified [in the UN Security Council Resolution 1593] have committed crimes against humanity and war crimes," but did not find sufficient evidence to prosecute for genocide.
Is there an answer to this question: To whom did the Security Council officially refer the situation in Darfur?

Answer:
Prosecutor of the International Criminal Court
