Question: Multiracial people who wanted to acknowledge their full heritage won a victory of sorts in 1997, when the Office of Management and Budget (OMB) changed the federal regulation of racial categories to permit multiple responses. This resulted in a change to the 2000 United States Census, which allowed participants to select more than one of the six available categories, which were, in brief: "White," "Black or African American," "Asian," "American Indian or Alaskan Native," "Native Hawaiian or other Pacific Islander," and "Other." Further details are given in the article: Race (U.S. census). The OMB made its directive mandatory for all government forms by 2003.
Is there an answer to this question: What was not one of the categories participants could choose on the 2000 United States Census?

Answer: unanswerable

Question: Slavs are the largest Indo-European ethno-linguistic group in Europe. They inhabit Central Europe, Eastern Europe, Southeast Europe, North Asia and Central Asia. Slavs speak Indo-European Slavic languages and share, to varying degrees, some cultural traits and historical backgrounds. From the early 6th century they spread to inhabit most of Central and Eastern Europe and Southeast Europe, whilst Slavic mercenaries fighting for the Byzantines and Arabs settled Asia Minor and even as far as Syria. The East Slavs colonised Siberia and Central Asia.[better source needed] Presently over half of Europe's territory is inhabited by Slavic-speaking communities, but every Slavic ethnicity has emigrated to other continents.

Question: Wary of protests, the Indian authorities have decided to shorten the route of the relay in New Delhi, and have given it the security normally associated with Republic Day celebrations, which are considered terrorist targets. Chinese intelligence's expectations of points on the relay route that would be particularly 'vulnerable' to protesters were presented to the Indian ambassador to Beijing, Nirupama Sen. The Indian media responded angrily to the news that the ambassador, a distinguished lady diplomat, was summoned to the Foreign Ministry at 2 am local time; the news was later denied by anonymous sources in Delhi. The Indian media reported that India's Commerce Minister, Kamal Nath, cancelled an official trip to Beijing in protest, though both Nath and Chinese sources have denied it.
Is there an answer to this question: At what time in the middle of the night was the diplomat summoned?

Answer: 2 am

Question: The Indonesian Archipelago is split by the Wallace Line. This line runs along what is now known to be a tectonic plate boundary, and separates Asian (Western) species from Australasian (Eastern) species. The islands between Java/Borneo and Papua form a mixed zone, where both types occur, known as Wallacea. As the pace of development accelerates and populations continue to expand in Southeast Asia, concern has increased regarding the impact of human activity on the region's environment. A significant portion of Southeast Asia, however, has not changed greatly and remains an unaltered home to wildlife. The nations of the region, with only few exceptions, have become aware of the need to maintain forest cover not only to prevent soil erosion but to preserve the diversity of flora and fauna. Indonesia, for example, has created an extensive system of national parks and preserves for this purpose. Even so, such species as the Javan rhinoceros face extinction, with only a handful of the animals remaining in western Java.
Is there an answer to this question: Name the line that splits the Indonesian Archipelago?

Answer:
Wallace Line
