Question: 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

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


Question: Passage: The Lakers opened the series with a 115–109 victory at the Boston Garden. In Game 2, the Lakers led 113–111 with 18 seconds left when Gerald Henderson stole a James Worthy pass to score a game tying layup and the Celtics eventually prevailed in overtime 124–121. In Game 3, the Lakers raced to an easy 137–104 victory as Magic Johnson dished out 21 assists. After the game, Larry Bird said his team played like "sissies" in an attempt to light a fire under his teammates. In Game 4, the Lakers had a five-point game lead with less than a minute to play, but made several execution errors as the Celtics tied the game and then came away with a 129–125 victory in overtime. The game was also marked by Celtic forward Kevin McHale's takedown of Laker forward Kurt Rambis on a breakaway layup which triggered the physical aspect of the rivalry. Kareem Abdul-Jabbar would go after Larry Bird later on in the third quarter, and 1981 Finals MVP Cedric Maxwell further antagonized the Lakers by following a missed James Worthy free throw by crossing the lane with his hands around his own neck, symbolizing that Worthy was "choking" under pressure. In Game 5, the Celtics took a 3–2 series lead as Larry Bird scored 34 points. The game was known as the "Heat Game", as it was played under 97 °F-heat, and without any air conditioning at the infamous Boston Garden. In Game 6, the Lakers evened the series with a 119–108 victory. In the game, the Lakers answered the Celtics rough tactics when Worthy shoved Cedric Maxwell into a basket support. After the game, a Laker fan threw a beer at Celtics guard M.L. Carr as he left the floor, causing him to label the series "all-out-war." In Game 7, the Celtics were led by Cedric Maxwell, who had 24 points, eight rebounds, and eight assists as they came away with a 111–102 victory. In the game the Lakers rallied from a 14-point deficit to three points down with one minute remaining, when Maxwell knocked the ball away from Magic Johnson. Dennis Johnson responded by sinking two free throws to seal the Celtics' victory. Larry Bird was named MVP of the series.

Question: Passage: Truman had acceded to the presidency in April 1945 after the death of Franklin D. Roosevelt. Defeating attempts to drop him from the ticket, Truman won the presidential nomination at the 1948 Democratic National Convention. The Democratic convention's civil rights plank caused a walk-out by several Southern delegates, who launched a third-party "Dixiecrat" ticket led by Governor Strom Thurmond of South Carolina. The Dixiecrats hoped to win enough electoral votes to force a contingent election in the House of Representatives, where they could extract concessions from either Dewey or Truman in exchange for their support. Truman also faced a challenge from the left in the form of former Vice President Henry A. Wallace, who launched the Progressive Party and challenged Truman's confrontational Cold War policies. Dewey, who was the leader of his party's moderate eastern wing and had been the 1944 Republican presidential nominee, defeated Senator Robert A. Taft and other challengers at the 1948 Republican National Convention.
