[EX Q]: Question: Which actor was cast as the title role in the Batwoman series following her appearance in the crossover? Passage 1:In May 2018, The CW president Mark Pedowitz and Arrow lead Stephen Amell announced at The CW's upfront presentation that Batwoman, fighting alongside the other Arrowverse heroes, would be introduced in the upcoming crossover. The fictional Gotham City would also appear. Despite the inclusion of the character and city, the crossover would not include the television series Gotham that airs on Fox. That July, the CW was planning a potential standalone Batwoman series after her appearance in the crossover; Caroline Dries, who was creating and writing the potential Batwoman series, was expected to consult on the crossover. It was confirmed that Legends of Tomorrow would not feature in the crossover. Legends of Tomorrow co-showrunner Phil Klemmer said because the crossover was being used to launch the Batwoman-led series, "it just became over capacity", and that because Legends of Tomorrow would have a 16-episode season, the crossover would have been "a tonal speed-bump, or a departure, and we just don't have time to step away from our story this year". Despite not being part of the official crossover, Legends of Tomorrow co-showrunner Keto Shimizu revealed "Legends of To-Meow-Meow", the show's episode airing the week of the crossover, would be "crossing over with ourselves" through the use of alternate time periods, and Adam Tsekhman guest stars as Gary Green in the Supergirl episode.

 Passage 3:He played for a variety of sides in two stints in the National Soccer League. The first stint was played almost entirely for Sydney United, for whom he played as a junior, and which culminated in playing in their runner-up 1996/97 side. After that season he moved to NAC Breda in the Netherlands, and after 2 seasons there went to Croatia's NK Rijeka, where he was the club's top scorer in 2000/01 with 10 goals. On his return to the NSL in season 2001/02, he rejoined Sydney United for a brief stay, before moving to city rival Sydney Olympic during the same season. He would spend the rest of the season and the next playing there, including scoring the only goal of the 2001/02 Grand Final against Perth Glory. In the final he was awarded the Joe Marston Medal, delivering Sydney Olympic their second NSL title, as well as playing in the runner up side the following season against Perth Glory.

[EX Q]: Question: The rightful heir to the Hungarian throne according to the Treaty of Nagyvarad was a king from which country? Passage 1:The famous and influential Swedish filmmaker, Ingmar Bergman, rose to prominence in the fifties. He began making films in the mid-forties, and in 1955, he made Smiles of a Summer Night, which brought him international attention. A year later, he made one of his most famous films, The Seventh Seal. In the 1960s, Bergman won the Academy Award for Best Foreign Language Film for two consecutive years, with The Virgin Spring (Jungfrukällan) in 1960 and Through a Glass Darkly (Såsom i en spegel) in 1961. He won the award again in 1983, for the early twentieth-century family drama Fanny and Alexander (Fanny och Alexander). Bergman has also been nominated for the Best Picture award once, with the 1973 Cries and Whispers (Viskningar och rop), the story of two sisters watching over their third sister's deathbed, both afraid she might die, but hoping she does. The film lost to The Sting, and oddly enough, it was not nominated in the Foreign Language Film category. It also gave Bergman the first of three nominations for Best Director. Ingmar Bergman also won four Golden Globe Awards for Best Foreign Language Film.
 Passage 2:Auckland was New Zealand's second capital from 1841 until 1865, when Parliament was permanently moved to Wellington after an argument that was had for one decade. The initial form of government was an executive council formed of public servant appointed by and responsible to the governor. This changed when the New Zealand Constitution Act 1852, an Act of the Parliament of the United Kingdom that granted self-government to the Colony of New Zealand, was received. This allowed for a bicameral General Assembly (or Parliament), consisting of the Governor, an appointed Legislative Council and an elected House of Representatives, with an Executive Council nominally appointed by the Governor. It also allowed for provincial governments, and six provinces were initially established. The first general election was held in 1853.
 Passage 3:In 1530 John Zápolya appointed him as the provost of the Buda cathedral and as a royal secretary. Between 1530-1539 he was also the deputy of the King and after his death he remained with his widow, Isabella Jagiellon. In 1541 he moved with her to Transylvania, but he mostly traveled fulfilling diplomatic services because of his disagreement with cardinal Juraj Utješinović's policy of claiming the Hungarian throne for Isabella's and Zápolya's infant son (instead of conceding it to Ferdinand I as per Treaty of Nagyvárad). Utješinović, appointed by Zápolya as a guardian of his son, John Sigismund Zápolya, fought against Ferdinand and allied himself with the Ottoman Empire.

[EX Q]: Question: Of the two players that each won three titles, are either still playing? Passage 1:Natural strontium is a mixture of four stable isotopes: Sr, Sr, Sr, and Sr. Their abundance increases with increasing mass number and the heaviest, Sr, makes up about 82.6% of all natural strontium, though the abundance varies due to the production of radiogenic Sr as the daughter of long-lived beta-decaying Rb. Of the unstable isotopes, the primary decay mode of the isotopes lighter than Sr is electron capture or positron emission to isotopes of rubidium, and that of the isotopes heavier than Sr is electron emission to isotopes of yttrium. Of special note are Sr and Sr. The former has a half-life of 50.6 days and is used to treat bone cancer due to strontium's chemical similarity and hence ability to replace calcium. While Sr (half-life 28.90 years) has been used similarly, it is also an isotope of concern in fallout from nuclear weapons and nuclear accidents due to its production as a fission product. Its presence in bones can cause bone cancer, cancer of nearby tissues, and leukemia. The 1986 Chernobyl nuclear accident contaminated about 30,000 km with greater than 10 kBq/m with Sr, which accounts for 5% of the core inventory of Sr.
 Passage 2:Before this year, the tournament was won by a home favorite on several occasions: Guy Forget in 1996, Fabrice Santoro in 1999, Arnaud Clément in 2006, and Gilles Simon in 2007. The record for most titles is three, won by the Swiss player Marc Rosset in its first two years in 1993 and 1994, as well as in 2000; the Swedish player Thomas Enqvist also won three, in 1997, 1998, and 2002. It is also one of the few ATP tournaments to have been won only by European players, with France with five (Forget, Santoro, Clément, Simon, and this year's winner Jo-Wilfried Tsonga), Sweden with 4 (Enqvist, Joachim Johansson), Switzerland with four (Rosset, Roger Federer), Germany with one (Boris Becker), Russia with one (Yevgeny Kafelnikov), Slovakia with one (Dominik Hrbatý), and Great Britain with one (Andy Murray).
 Passage 3:On a smuggling run from Colombia, having dumped packages of cocaine off near Blairsville, Georgia, Thornton jumped from his auto-piloted Cessna 404. In the September 11, 1985, jump, he was caught in his parachute and ended up in a free fall to the ground. His dead body was found in the back yard of Knoxville, Tennessee, resident Fred Myers. The plane crashed over away in Hayesville, North Carolina. At the time of his death Thornton was wearing night vision goggles, a bulletproof vest, Gucci loafers, and a green army duffel bag containing approximately 40 kilos (88 lbs.) of cocaine valued at $15 million, $4,500 in cash, six . gold Krugerrands, knives, and two pistols. Three months later, a dead black bear was found in the Chattahoochee National Forest that had apparently overdosed on cocaine dropped by Thornton.
