Question: Perhaps the biggest sustainability problem in Tucson, with its high desert climate, is potable water supply. The state manages all water in Arizona through its Arizona Department of Water Resources (ADWR). The primary consumer of water is Agriculture (including golf courses), which consumes about 69% of all water. Municipal (which includes residential use) accounts for about 25% of use. Energy consumption and availability is another sustainability issue. However, with over 300 days of full sun a year, Tucson has demonstrated its potential to be an ideal solar energy producer.
Is there an answer to this question: How is most of Tucson's water used?

Answer: Agriculture (including golf courses)


Question: In the 1990s Rhino Records issued a series of boxed sets of 78 rpm reissues of early rock and roll hits, intended for owners of vintage jukeboxes. This was a disaster because Rhino did not warn customers that their records were made of vinyl, and that the vintage 78 RPM juke boxes were designed with heavy tone arms and steel needles to play the hard shellac records of their time. This failure to warn customers gave the Rhino 78 records a bad reputation,[citation needed] as they were destroyed by old juke boxes and old record players but played very well on newer 78-capable turntables with modern lightweight tone arms and jewel needles.
Is there an answer to this question: How did the 1990 release of 78 rpm effect Rhino Records?

Answer: bad reputation
