[EX Q]: Question: What was his first victory of the year? Passage:Race 1 was held on Saturday 10 May. Mark Winterbottom took his second race victory of the year, a surprisingly comfortable win ahead of the HRT pair of Mark Skaife and Garth Tander. Tander was pushed hard by Steven Richards and Craig Lowndes. A collision at race start saw Jason Bright touch Greg Murphy who in turn made contact with Michael Caruso, sending Bright and Caruso out of control towards turn 7, where crossing the track Caruso struck Shane van Gisbergen. The incident triggered a safety car. Jamie Whincup and Will Davison charged through to seventh and eight positions from poor qualifying places. James Courtney was fighting amongst that group but fading rear tyres led Courtney to attempt defensive moves that raised the ire of race control, leading to first the bad sportsmanship flag, then a black flag drive through penalty which dropped him down field.

[EX Q]: Question: What country did Commandino study in? Passage:Born in Urbino, he studied at Padua and at Ferrara, where he received his doctorate in medicine. He was most famous for his central role as translator of works of ancient mathematicians. In this, his sources were primarily written in Greek and secondarily in Arabic, while his translations were primarily in Latin and secondarily in Italian. He was responsible for the publication of many treatises of Archimedes. He also translated the works of Aristarchus of Samos (On the sizes and distances of the Sun and the Moon), Pappus of Alexandria (Mathematical collection), Hero of Alexandria (Pneumatics), Ptolemy of Alexandria (Planisphere and Analemma), Apollonius of Perga (Conics) and Euclid of Alexandria (Elements). Among his pupils was Guidobaldo del Monte and Bernardino Baldi. Commandino maintained a correspondence with the astronomer Francesco Maurolico. The proposition known as Commandino's theorem first appears in his work on centers of gravity.

[EX Q]: Question: Which of Vidal's first two plays was considered more successful? Passage:After publishing the plays Weekend (1968) and An Evening With Richard Nixon (1972) and the novel Two Sisters: A Novel in the Form of a Memoir (1970), Vidal concentrated upon the essay and developed two types of fiction. The first type is about American history, novels specifically about the nature of national politics. About those historical novels, the critic Harold Bloom said that "Vidal's imagination of American politics ... is so powerful as to compel awe". The historical novels formed the seven-book series, Narratives of Empire: (i) Burr (1973), (ii) 1876 (1976), (iii) Lincoln (1984), (iv) Empire (1987), (v) Hollywood (1990), (vi) Washington, D.C. (1967) and (vii) The Golden Age (2000). Besides U.S. history, Vidal also explored and analyzed the history of the ancient world, specifically the Axial Age (800200 B.C.), with the novel Creation (1981). The novel was published without four chapters that were part of the manuscript he submitted to the publisher; years later, Vidal restored the chapters to the text and re-published the novel Creation in 2002.
