The Genographic Project, launched by the National Geographic Society and IBM in partnership with the Waitt Family Foundation, was officially announced on April 13, 2005. It uses DNA analysis to study human migration patterns. The date April 13, 2005 is the correct launch date.

Karl Baedeker's first guidebook, published in 1832, was about the Rhine River. This established the famous Baedeker travel guide series that became synonymous with detailed European travel information.

Britain introduced pensions later (1908), the US even later (1935 with Social Security), and India after independence.

Mount Cleveland Volcano in Alaska had a significant eruption in 2009, with multiple eruptive episodes throughout the year. While Cleveland Volcano has erupted in other years including 2006, 2008, and historically in 1944, 2009 was one of its most active recent periods. The question asks when the eruption happens, and 2009 is a correct answer among the options.
