PROBLEM: By about 1910,[note 1] bound collections of empty sleeves with a paperboard or leather cover, similar to a photograph album, were sold as record albums that customers could use to store their records (the term "record album" was printed on some covers). These albums came in both 10-inch and 12-inch sizes. The covers of these bound books were wider and taller than the records inside, allowing the record album to be placed on a shelf upright, like a book, suspending the fragile records above the shelf and protecting them.

SOLUTION: When could record album covers first be found?

PROBLEM: Since 2001, Miami has been undergoing a large building boom with more than 50 skyscrapers rising over 400 feet (122 m) built or currently under construction in the city. Miami's skyline is ranked third-most impressive in the U.S., behind New York City and Chicago, and 19th in the world according to the Almanac of Architecture and Design. The city currently has the eight tallest (as well as thirteen of the fourteen tallest) skyscrapers in the state of Florida, with the tallest being the 789-foot (240 m) Four Seasons Hotel & Tower.

SOLUTION: How many 400+ foot skyscrapers have been built or are in the process of being built in Miami since 2001?

PROBLEM: Southern Italy was also part of the Norman kingdom but great mosaics did not survive in this area except the fine mosaic pavement of the Otranto Cathedral from 1166, with mosaics tied into a tree of life, mostly still preserved. The scenes depict biblical characters, warrior kings, medieval beasts, allegories of the months and working activity. Only fragments survived from the original mosaic decoration of Amalfi's Norman Cathedral. The mosaic ambos in the churches of Ravello prove that mosaic art was widespread in Southern Italy during the 11th–13th centuries.

SOLUTION:
What region of italy was part of the Norman empire?
