Problem: Annelid:

Charles Darwin's book The Formation of Vegetable Mould through the Action of Worms (1881) presented the first scientific analysis of earthworms' contributions to soil fertility. Some burrow while others live entirely on the surface, generally in moist leaf litter. The burrowers loosen the soil so that oxygen and water can penetrate it, and both surface and burrowing worms help to produce soil by mixing organic and mineral matter, by accelerating the decomposition of organic matter and thus making it more quickly available to other organisms, and by concentrating minerals and converting them to forms that plants can use more easily. Earthworms are also important prey for birds ranging in size from robins to storks, and for mammals ranging from shrews to badgers, and in some cases conserving earthworms may be essential for conserving endangered birds.

How does burrowers' loosening help the soil?
---
A: oxygen and water can penetrate it


Problem: While the "footprint" of the Astra 2D satellite was smaller than that of Astra 2A, from which it was previously broadcast encrypted, it meant that viewers with appropriate equipment were able to receive BBC channels "free-to-air" over much of Western Europe. Consequently, some rights concerns have needed to be resolved with programme providers such as Hollywood studios and sporting organisations, which have expressed concern about the unencrypted signal leaking out. This led to some broadcasts being made unavailable on the Sky Digital platform, such as Scottish Premier League and Scottish Cup football, while on other platforms such broadcasts were not disrupted. Later, when rights contracts were renewed, this problem was resolved.
With the right tools, what area could get free BBC broadcasts from Astra 2D?
---
Answer: Western Europe


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On October 25, 1989, the Supreme Soviet voted to eliminate special seats for the Communist Party and other official organizations in national and local elections, responding to sharp popular criticism that such reserved slots were undemocratic. After vigorous debate, the 542-member Supreme Soviet passed the measure 254-85 (with 36 abstentions). The decision required a constitutional amendment, ratified by the full congress, which met December 12–25. It also passed measures that would allow direct elections for presidents of each of the 15 constituent republics. Gorbachev strongly opposed such a move during debate but was defeated.
What did the Communist Party lose on October 25, 1989 with regards to elections?
A: special seats


Context and 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.
When were the OMB racial directive made mandatory for every government form?
Answer: 2003


Question: On December 30, 1922, with the creation of the Soviet Union, Russia became one of six republics within the federation of the Union of Soviet Socialist Republics.

By that time, Soviet Russia had gained roughly the same borders of the old Tsardom of Russia before the Great Northern War of 1700.
Is there an answer to this question: How many republics were in the USSR?

Answer: six
