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: In 1997, Compton signed up with a new team, Impact Motorsports, to run the No. 86 Ford F-150 for the NASCAR Craftsman Truck Series Rookie of the Year Award. During his initial Truck Series season, Compton had three Top 5 finishes and a 13th-place finish in points, but fell well short of the top rookie award. For the 1998 season, in the third race of the season held at Phoenix International Raceway, Compton won his first career pole position, and finished in third in the race. The next week at Portland Speedway, he led all but two laps and won his first career Truck Series race. He got another win later that season at Heartland Park Topeka. He finished seventh in the final points standings and was named the Most Popular Driver. Compton had high hopes for 1999 season as Impact switched to Dodge Rams and getting a teammate in Randy Tolsma, but he failed to go to victory lane that season, although he did finish fourth in the points. Late that season, Compton began competing in some Winston Cup races for Melling Racing. Soon afterwards, Melling announced that Compton would driver theirNo. 9 Ford Taurus in the Winston Cup Series in 2000 season.
 Link Information: The Chevy Trucks 150 was held April 19 at Phoenix International Raceway. Stacy Compton won the pole.

Top ten result Answer: April 19

SOLUTION: On what date did Compton finish third in the race?

PROBLEM: Passage: After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.
