In March 1949, as RCA released the 45, Columbia released several hundred 7 inch 33 1/3 rpm small spindle hole singles. This format was soon dropped as it became clear that the RCA 45 was the single of choice and the Columbia 12 inch LP would be the 'album' of choice. The first release of the 45 came in seven colors: black 47-xxxx popular series, yellow 47-xxxx juvenile series, green (teal) 48-xxxx country series, deep red 49-xxxx classical series, bright red (cerise) 50-xxxx blues/spiritual series, light blue 51-xxxx international series, dark blue 52-xxxx light classics. All colors were soon dropped in favor of black because of production problems. However, yellow and deep red were continued until about 1952. The first 45 rpm record created for sale was "PeeWee the Piccolo" RCA 47-0147 pressed in yellow translucent vinyl at the Sherman Avenue plant, Indianapolis Dec. 7, 1948, R.O. Price, plant manager.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which colors of 45 were available as late as 1952 before being discontinued?
Ah, so.. yellow and deep red

Glaciers pick up rocks and sediment with them as they flow. This causes erosion and the formation of valleys over time. The Inn valley is an example of a valley carved by glaciers during the ice ages with a typical terraced structure caused by erosion. Eroded rocks from the most recent ice age lie at the bottom of the valley while the top of the valley consists of erosion from earlier ice ages. Glacial valleys have characteristically steep walls (reliefs); valleys with lower reliefs and talus slopes are remnants of glacial troughs or previously infilled valleys. Moraines, piles of rock picked up during the movement of the glacier, accumulate at edges, center and the terminus of glaciers.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are Moraines?
Ah, so.. piles of rock picked up during the movement of the glacier

Ann Arbor has a long history of openness to marijuana, given Ann Arbor's decriminalization of cannabis, the large number of medical marijuana dispensaries in the city (one dispensary, called People's Co-op, was directly across the street from Michigan Stadium until zoning forced it to move one mile to the west), the large number of pro-marijuana residents, and the annual Hash Bash: an event that is held on the first Saturday of April. Until (at least) the successful passage of Michigan's medical marijuana law, the event had arguably strayed from its initial intent, although for years, a number of attendees have received serious legal responses due to marijuana use on University of Michigan property, which does not fall under the City's progressive and compassionate ticketing program.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are the Medical marijuana dispensaries called in the city?
Ah, so..
People's Co-op
