Problem: During World War II, the development of the anti-aircraft proximity fuse required an electronic circuit that could withstand being fired from a gun, and could be produced in quantity. The Centralab Division of Globe Union submitted a proposal which met the requirements: a ceramic plate would be screenprinted with metallic paint for conductors and carbon material for resistors, with ceramic disc capacitors and subminiature vacuum tubes soldered in place. The technique proved viable, and the resulting patent on the process, which was classified by the U.S. Army, was assigned to Globe Union. It was not until 1984 that the Institute of Electrical and Electronics Engineers (IEEE) awarded Mr. Harry W. Rubinstein, the former head of Globe Union's Centralab Division, its coveted Cledo Brunetti Award for early key contributions to the development of printed components and conductors on a common insulating substrate. As well, Mr. Rubinstein was honored in 1984 by his alma mater, the University of Wisconsin-Madison, for his innovations in the technology of printed electronic circuits and the fabrication of capacitors.
What award did Rubinstein win in 1984 for his contributions?

Answer: Cledo Brunetti Award


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During the mid-2000s, the city witnessed its largest real estate boom since the Florida land boom of the 1920s. During this period, the city had well over a hundred approved high-rise construction projects in which 50 were actually built. In 2007, however, the housing market crashed causing lots of foreclosures on houses. This rapid high-rise construction, has led to fast population growth in the city's inner neighborhoods, primarily in Downtown, Brickell and Edgewater, with these neighborhoods becoming the fastest-growing areas in the city. The Miami area ranks 8th in the nation in foreclosures. In 2011, Forbes magazine named Miami the second-most miserable city in the United States due to its high foreclosure rate and past decade of corruption among public officials. In 2012, Forbes magazine named Miami the most miserable city in the United States because of a crippling housing crisis that has cost multitudes of residents their homes and jobs. The metro area has one of the highest violent crime rates in the country and workers face lengthy daily commutes.
When did the Florida land boom occur?
A: 1920s

Question: The curious location on Catalina Island stemmed from Cubs owner William Wrigley Jr.'s then-majority interest in the island in 1919. Wrigley constructed a ballpark on the island to house the Cubs in spring training: it was built to the same dimensions as Wrigley Field. (The ballpark is long gone, but a clubhouse built by Wrigley to house the Cubs exists as the Catalina County Club.) However, by 1951 the team chose to leave Catalina Island and spring training was shifted to Mesa, Arizona. The Cubs' 30-year association with Catalina is chronicled in the book, The Cubs on Catalina, by Jim Vitti . . . which was named International 'Book of the Year' by The Sporting News.
Is there an answer to this question: What did Wrigley construct on the island to house the Cubs in Spring training?

Answer: a ballpark
