PROBLEM: After leaving Edison's company Tesla partnered with two businessmen in 1886, Robert Lane and Benjamin Vail, who agreed to finance an electric lighting company in Tesla's name, Tesla Electric Light & Manufacturing. The company installed electrical arc light based illumination systems designed by Tesla and also had designs for dynamo electric machine commutators, the first patents issued to Tesla in the US.

PROBLEM: Aside from the official forms of their respective languages, the four linguistic regions of Switzerland also have their local dialectal forms. The role played by dialects in each linguistic region varies dramatically: in the German-speaking regions, Swiss German dialects have become ever more prevalent since the second half of the 20th century, especially in the media, such as radio and television, and are used as an everyday language, while the Swiss variety of Standard German is almost always used instead of dialect for written communication (c.f. diglossic usage of a language). Conversely, in the French-speaking regions the local dialects have almost disappeared (only 6.3% of the population of Valais, 3.9% of Fribourg, and 3.1% of Jura still spoke dialects at the end of the 20th century), while in the Italian-speaking regions dialects are mostly limited to family settings and casual conversation.

SOLUTION: How many linguistic regions of Switzerland have their own form of local dialect?

PROBLEM: In 1989, the first full season with night baseball at Wrigley Field, Don Zimmer's Cubs were led by a core group of veterans in Ryne Sandberg, Rick Sutcliffe and Andre Dawson, who were boosted by a crop of youngsters such as Mark Grace, Shawon Dunston, Greg Maddux, Rookie of the Year Jerome Walton, and Rookie of the Year Runner-Up Dwight Smith. The Cubs won the NL East once again that season winning 93 games. This time the Cubs met the San Francisco Giants in the NLCS. After splitting the first two games at home, the Cubs headed to the Bay Area, where despite holding a lead at some point in each of the next three games, bullpen meltdowns and managerial blunders ultimately led to three straight losses. The Cubs couldn't overcome the efforts of Will Clark, whose home run off Maddux, just after a managerial visit to the mound, led Maddux to think Clark knew what pitch was coming. Afterward, Maddux would speak into his glove during any mound conversation, beginning what is a norm today. Mark Grace was 11–17 in the series with 8 RBI. Eventually, the Giants lost to the "Bash Brothers" and the Oakland A's in the famous "Earthquake Series."

SOLUTION:
What year was the first full season with night baseball at Wrigley Field?
