Problem: Biodiversity:

The fossil record suggests that the last few million years featured the greatest biodiversity in history. However, not all scientists support this view, since there is uncertainty as to how strongly the fossil record is biased by the greater availability and preservation of recent geologic sections. Some scientists believe that corrected for sampling artifacts, modern biodiversity may not be much different from biodiversity 300 million years ago., whereas others consider the fossil record reasonably reflective of the diversification of life. Estimates of the present global macroscopic species diversity vary from 2 million to 100 million, with a best estimate of somewhere near 9 million, the vast majority arthropods. Diversity appears to increase continually in the absence of natural selection.

Why are some scientists uncertain about the diversification of life?

Problem: While the original Xbox sold poorly in Japan, selling just 2 million units while it was on the market (between 2002 and 2005),[citation needed] the Xbox 360 sold even more poorly, selling only 1.5 million units from 2005 to 2011. Edge magazine reported in August 2011 that initially lackluster and subsequently falling sales in Japan, where Microsoft had been unable to make serious inroads into the dominance of domestic rivals Sony and Nintendo, had led to retailers scaling down and in some cases discontinuing sales of the Xbox 360 completely.
Between 2005 and 2011, how many 360 consoles were sold in Japan?

Answer: 1.5 million units


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
There are seven current masjids in the Greater Richmond area, with three more currently in construction, accommodating the growing Muslim population, the first one being Masjid Bilal. In the 1950s, Muslims from the East End got organized under Nation of Islam (NOI). They used to meet in Temple #24 located on North Avenue. After the NOI split in 1975, the Muslims who joined mainstream Islam, start meeting at Shabaaz Restaurant on Nine Mile Road. By 1976, the Muslims used to meet in a rented church. They tried to buy this church, but due to financial difficulties the Muslims instead bought an old grocery store at Chimbarazoo Boulevard, the present location of Masjid Bilal. Initially, the place was called "Masjid Muhammad #24". Only by 1990 did the Muslims renamed it to "Masjid Bilal". Masjid Bilal was followed by the Islamic Center of Virginia, ICVA masjid. The ICVA was established in 1973 as a non profit tax exempt organization. With aggressive fundraising, ICVA was able to buy land on Buford road. Construction of the new masjid began in the early 1980s. The rest of the five current masjids in the Richmond area are Islamic Center of Richmond (ICR) in the west end, Masjid Umm Barakah on 2nd street downtown, Islamic Society of Greater Richmond (ISGR) in the west end, Masjidullah in the north side, and Masjid Ar-Rahman in the east end.
What year saw the establishment of the Islamic Center of Virginia?
A: 1973

Question: Genocide has become an official term used in international relations. The word genocide was not in use before 1944. Before this, in 1941, Winston Churchill described the mass killing of Russian prisoners of war and civilians as "a crime without a name". In that year, a Polish-Jewish lawyer named Raphael Lemkin, described the policies of systematic murder founded by the Nazis as genocide. The word genocide is the combination of the Greek prefix geno- (meaning tribe or race) and caedere (the Latin word for to kill). The word is defined as a specific set of violent crimes that are committed against a certain group with the attempt to remove the entire group from existence or to destroy them.
Is there an answer to this question: Who referred to acts of genocide in 1945?

Answer: unanswerable


Problem: Queen Victoria:

Victoria visited mainland Europe regularly for holidays. In 1889, during a stay in Biarritz, she became the first reigning monarch from Britain to set foot in Spain when she crossed the border for a brief visit. By April 1900, the Boer War was so unpopular in mainland Europe that her annual trip to France seemed inadvisable. Instead, the Queen went to Ireland for the first time since 1861, in part to acknowledge the contribution of Irish regiments to the South African war. In July, her second son Alfred ("Affie") died; "Oh, God! My poor darling Affie gone too", she wrote in her journal. "It is a horrible year, nothing but sadness & horrors of one kind & another."

Which of Queen Victoria's children died in July of that year? 
---
A:
her second son Alfred
