Context and question: It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on the way they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
What are the technologies used to capture solar energy characterized as?
Answer: passive solar or active solar
Context and question: 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."
What year was the first full season with night baseball at Wrigley Field?
Answer: 1989
Context and question: The topic of language for writers from Dalmatia and Dubrovnik prior to the 19th century made a distinction only between speakers of Italian or Slavic, since those were the two main groups that inhabited Dalmatian city-states at that time. Whether someone spoke Croatian or Serbian was not an important distinction then, as the two languages were not distinguished by most speakers. This has been used as an argument to state that Croatian literature Croatian per se, but also includes Serbian and other languages that are part of Serbo-Croatian, These facts undermine the Croatian language proponents' argument that modern-day Croatian is based on a language called Old Croatian.
Prior to the 19th century where did Croatians and Serbians live?
