Problem: The Portuguese Restoration War was the name given by nineteenth-century Romantic historians to the war between Portugal and Spain that began with the Portuguese revolution of 1640 and ended with the Treaty of Lisbon in 1668. The revolution of 1640 ended the 60-year Iberian Union. The period from 1640 to 1668 was marked by periodic skirmishes between Portugal and Spain, as well as short episodes of more serious warfare, much of it occasioned by Spanish and Portuguese entanglements with non-Iberian powers. Spain was involved in the Thirty Years' War until 1648 and the Franco-Spanish War until 1659, while Portugal was involved in the Dutch-Portuguese War until 1663. In the seventeenth century and afterwards, this period of sporadic conflict was simply known, in Portugal and elsewhere, as the Acclamation War. The war established the House of Braganza as Portugal's new ruling dynasty, replacing the House of Habsburg. This ended the so-called Iberian Union.

How many years did the revolution last?
Answer: 28

Problem: Real GDP per capita (measured in 2009 dollars) was $52,444 in 2017 and has been growing each year since 2010. It grew 3.0% per year on average in the 1960s, 2.1% in the 1970s, 2.4% in the 1980s, 2.2% in the 1990s, 0.7% in the 2000s, and 0.9% from 2010 to 2017. Reasons for slower growth since 2000 are debated by economists and may include aging demographics, slower population and growth in labor force, slower productivity growth, reduced corporate investment, greater income inequality reducing demand, lack of major innovations, and reduced labor power. The U.S. ranked 20th out of 220 countries in GDP per capita in 2017. Among the modern U.S. Presidents, Bill Clinton had the highest cumulative percent real GDP increase during his two terms, Reagan second and Obama third.

How many years was the GDP per capita at 0.9% between 2010-2017?
Answer: 7
