Input: Article: By September 2008, average U.S. housing prices had declined by over 20% from their mid-2006 peak. As prices declined, borrowers with adjustable-rate mortgages could not refinance to avoid the higher payments associated with rising interest rates and began to default. During 2007, lenders began foreclosure proceedings on nearly 1.3 million properties, a 79% increase over 2006. This increased to 2.3 million in 2008, an 81% increase vs. 2007. By August 2008, 9.2% of all U.S. mortgages outstanding were either delinquent or in foreclosure. By September 2009, this had risen to 14.4%.

Now answer this question: What was the percentage increase on foreclosure proceedings from 2007 to 2008?

Output: 81%

Here is a question about this article: The United Kingdom has traditionally been governed as a unitary state by the Westminster Parliament in London. Instead of adopting a federal model, the UK has relied on gradual devolution to decentralise political power. Devolution in the UK began with the Government of Ireland Act 1914 which granted home rule to Ireland as a constituent country of the former United Kingdom of Great Britain and Ireland. Following the partition of Ireland in 1921 which saw the creation of the sovereign Irish Free State (which eventually evolved into the modern day Republic of Ireland), Northern Ireland retained its devolved government through the Parliament of Northern Ireland, the only part of the UK to have such a body at this time. This body was suspended in 1972 and Northern Ireland was governed by direct rule during the period of conflict known as The Troubles.
What is the answer to this question: How has United Kingdom been governed?
