PROBLEM: Passage: Although originally proposed to the French space agency CNES, it was considered too complex and expensive for a single national programme. Its acceptance within the European Space Agency's scientific programme, in 1980, was the result of a lengthy process of study and lobbying. The underlying scientific motivation was to determine the physical properties of the stars through the measurement of their distances and space motions, and thus to place theoretical studies of stellar structure and evolution, and studies of galactic structure and kinematics, on a more secure empirical basis. Observationally, the objective was to provide the positions, parallaxes, and annual proper motions for some 100,000 stars with an unprecedented accuracy of 0.002 arcseconds, a target in practice eventually surpassed by a factor of two. The name of the space telescope, "Hipparcos" was an acronym for High Precision Parallax Collecting Satellite, and it also reflected the name of the ancient Greek astronomer Hipparchus, who is considered the founder of trigonometry and the discoverer of the precession of the equinoxes (due to the Earth wobbling on its axis).
 Link Information: when ESRO was merged with ELDO. ESA had ten founding member states: Belgium, Denmark, France, West Germany, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom.  Answer: Belgium

SOLUTION: What countries make up the agency that Hipparcos was accepted to after being considered too complex for CNES?

PROBLEM: Passage: Evan Weiss grew up in Cherry Hill, New Jersey. His first exposure to the genre of emo was hearing the band Sunny Day Real Estate in the seventh grade while browsing a record shop. He continued his interest in music through buying Jade Tree and Polyvinyl records and going to local shows in Philadelphia. In the "fourth or fifth grade", Weiss started, with school friends, the band J.A.R., which eventually became The Progress, garnering modest local success. He was unable to convince his bandmates to play in the band full-time, and after their breakup in 2008 he started a solo project under the moniker Into It Over It. He first released music through two unorthodox concept projects: 52 Weeks, entailing the writing, recording and release of one song each week for a year (later released as a compilation record); and Twelve Towns, a twelve song project initially released over six separate splits with several different bands and each song being named after a town. In May 2011, the band made an appearance at Bled Fest. A month later, Weiss released Into It Over It's first studio album, Proper on No Sleep Records, produced by Ed Rose. In the last two months of the year, Into It Over It supported The Swellers on their tour of the UK and Europe. In March and April the next year, Into It Over It supported The Wonder Years on the Glamour Kills Spring 2012 tour in the US. To promote the tour, a compilation showcasing the bands covering each others' songs with released. Into It Over It's contribution was a cover of The Wonder Years's track "Don't Let Me Cave In". This was followed up in 2013 with Intersections, released on Triple Crown Records and on Big Scary Monsters in UK/Europe.
 Link Information: In 1992, guitarist Dan Hoerner and bassist Nate Mendel met when they became housemates at the University of Washington. After jam sessions, they decided to form a band Answer: 1992

SOLUTION: The band that exposed Weiss to the emo genre was formed in what year?

PROBLEM: Passage: Randall enlisted as a private in the 4th Pennsylvania Volunteer Infantry in the April 1861. He then accepted appointment to the 4th U.S. Infantry as second lieutenant in October. He served in New York and Washington, D.C., and in the field with the Army of the Potomac.

He was appointed a brevet captain for gallant service in the Battle of Antietam. He served as a major in the 14th New York Heavy Artillery Regiment, part of Major General Ambrose Burnside's IX Corps on the Richmond-Petersburg Front in 1864, and was commander of the regiment at the Battle of the Crater. The Dansville Advertiser reported on 7 September that he assumed command of the regiment on 18 August. This article also reports that he was wounded in the battle on 19 August.
