Input: Read this: Alexander Graham Bell was ranked 57th among the 100 Greatest Britons (2002) in an official BBC nationwide poll, and among the Top Ten Greatest Canadians (2004), and the 100 Greatest Americans (2005). In 2006 Bell was also named as one of the 10 greatest Scottish scientists in history after having been listed in the National Library of Scotland's 'Scottish Science Hall of Fame'. Bell's name is still widely known and used as part of the names of dozens of educational institutes, corporate namesakes, street and place names around the world.
Question: In 2004 Bell was listed in the top how many Greatest Canadians?

Output: 10

To the south and east of it is the Democratic Republic of Congo. It is also bounded by Gabon to the west, Cameroon and the Central African Republic to the north, and Cabinda (Angola) to the southwest. It has a short coast on the Atlantic Ocean.

Output: unanswerable

Input: Read this: Regularity is a concept based on adherence to Masonic Landmarks, the basic membership requirements, tenets and rituals of the craft. Each Grand Lodge sets its own definition of what these landmarks are, and thus what is Regular and what is Irregular (and the definitions do not necessarily agree between Grand Lodges). Essentially, every Grand Lodge will hold that its landmarks (its requirements, tenets and rituals) are Regular, and judge other Grand Lodges based on those. If the differences are significant, one Grand Lodge may declare the other "Irregular" and withdraw or withhold recognition.
Question: What are never considered "Irregular"?

Output: unanswerable

Input: Read this: At times when a death sentence is affirmed on direct review, it is considered final. Yet, supplemental methods to attack the judgment, though less familiar than a typical appeal, do remain. These supplemental remedies are considered collateral review, that is, an avenue for upsetting judgments that have become otherwise final. Where the prisoner received his death sentence in a state-level trial, as is usually the case, the first step in collateral review is state collateral review. (If the case is a federal death penalty case, it proceeds immediately from direct review to federal habeas corpus.) Although all states have some type of collateral review, the process varies widely from state to state. Generally, the purpose of these collateral proceedings is to permit the prisoner to challenge his sentence on grounds that could not have been raised reasonably at trial or on direct review. Most often these are claims, such as ineffective assistance of counsel, which requires the court to consider new evidence outside the original trial record, something courts may not do in an ordinary appeal. State collateral review, though an important step in that it helps define the scope of subsequent review through federal habeas corpus, is rarely successful in and of itself. Only around 6 percent of death sentences are overturned on state collateral review. In 2010, the death sentences of 53 inmates were overturned as a result of legal appeals or high court reversals.
Question: About what percentage of capital convictions are overturned due to state collateral review?
