Problem: Background: Roberto Mangabeira Unger (; born 24 March 1947) is a philosopher and politician. He has developed his views and positions across many fields, including social, political, and economic theory. In legal theory, he is best known by his work in the 1970s and 80s while at Harvard Law School as part of the Critical Legal Studies movement, which is held to have helped disrupt the methodological consensus in American law schools. His political activity helped the transition to democracy in Brazil in the aftermath of the military regime, and culminated with his appointment as Brazil's Minister of Strategic Affairs in 2007 and again in 2015.
Context: The beginning of Unger's academic career began with the books Knowledge and Politics and Law in Modern Society, published in 1975 and 1976 respectively. These works led to the co-founding of Critical Legal Studies (CLS) with Duncan Kennedy and Morton Horwitz. The movement stirred up controversy in legal schools across America as it challenged standard legal scholarship and made radical proposals for legal education. By the early 1980s, the CLS movement touched off a heated internal debate at Harvard, pitting the CLS scholars against the older, more traditional scholars.  Throughout much of the 1980s, Unger worked on his magnum opus, Politics: A Work In Constructive Social Theory, a three volume work that assessed classical social theory and developed a political, social, and economic alternative. The series is based on the premise of society as an artifact, and rejects the necessity of certain institutional arrangements. Published in 1987, Politics was foremost a critique of contemporary social theory and politics; it developed a theory of structural and ideological change, and gave an alternative account of world history. By first attacking the idea that there is a necessary progression from one set of institutional arrangements to another, e.g. feudalism to capitalism, it then built an anti-necessitarian theory of social change, theorizing the transition from one set of institutional arrangements to another.  Unger devoted much of the following decades to further elaborating on the insights developed in Politics by working out the political and social alternatives. What Should Legal Analysis Become? (Verso, 1996) developed tools to reimagine the organization of social life. Democracy Realized: The Progressive Alternative (Verso, 1998) and What Should the Left Propose? (Verso, 2005) put forth alternative institutional proposals.
Question: Did he author those books?
Answer: published in 1975 and 1976 respectively.

Problem: Background: Drazen Petrovic (pronounced [draZen petrovitc]; October 22, 1964 - June 7, 1993) was a Croatian professional basketball player. A shooting guard, he initially achieved success playing professional basketball in Europe in the 1980s, before joining the National Basketball Association (NBA) in 1989. A star on multiple stages, Petrovic earned two silver medals and one bronze in Olympic basketball, a gold and a bronze in the FIBA World Cup, a gold and a bronze in the FIBA EuroBasket, and two EuroLeague titles. He represented Yugoslavia's national team and, later, Croatia's national team.
Context: After spending a year serving the mandatory time in the military, Petrovic followed his brother's footsteps and moved to Cibona to form, at that time, the best backcourt duo in Europe. The very first year in Cibona he won both the Yugoslav League championship and the Yugoslav National Cup. To top it all off, the 87-78 victory over the Spanish League club Real Madrid, to which Petrovic contributed with 36 points, brought him and Cibona their first European Cup title. The second came the following year, as Petrovic scored 22 points and Cibona defeated the USSR Premier League club Zalgiris Kaunas, which starred the legendary Arvydas Sabonis. The same year brought another Yugoslav national cup title for Cibona, seeing Petrovic score 46 against the old rival Bosna. In 1987, Petrovic earned his third European trophy: a 2nd-tier European Cup Winners' Cup title against the Italian League club Scavolini Pesaro, whose net he filled with 28 points.  Petrovic's scoring average during the four years with Cibona stood at 37.7 points in the Yugoslavian first division and 33.8 in all of the European wide competitions that he played in, with personal one-time bests of 112 (40/60 FG, 10/20 3Pts, 22/22 FT) in the Yugoslavian League, and 62 points in the 3rd-tier European league, the Korac Cup, respectively. His scoring sheet was often known to show 40, 50, even 60 in a single game; in a 1985-86 season European League game against Limoges, Petrovic scored ten 3-pointers, including seven in a row during a first half stretch, for a final tally of 51 points and 10 assists; the same season he scored 45 points and dished out 25 assists against the reigning Italian League champions Simac Milano.  Petrovic needed new challenges, which Cibona and the Yugoslavian League could not offer. Across the Atlantic, the Portland Trail Blazers of the NBA had already used their third round pick on young Petrovic in 1986. However, he decided to postpone his departure to the United States. In 1988, he signed with Real Madrid instead, for at that time a hefty sum of around US$4 million. The transfer wasn't without controversy as the Yugoslav sporting laws stipulated that players weren't allowed to professionally move abroad until reaching 28 years of age, while Petrovic was still only 23 when he signed with the famous Madrid club. In 2014, Jose Antonio Arizaga, the sports agent who played a key role in Petrovic's summer 1988 transfer from Cibona to Real, recalled a few details from this transaction: "I spoke to Mirko Novosel, Drazen's coach at Cibona, and he told me two things. One, every problem in Yugoslavia can be taken care of with the right amount of money, and two, if Drazen leaves, every other player under 28 will be leaving and it'll be chaos. So, you can imagine all the individuals I had to bribe and all the places where I had to pay up in order to circumvent this law".
