Input: Consider Input: Question: On what day did the season begin that Mark Sloan first appears? Passage 1:Tropical Storm Carlotta was a moderate tropical cyclone that caused flooding in several states in southwestern and central Mexico. Carlotta, the third named storm of the 2018 Pacific hurricane season, formed as the result of a breakdown in the Intertropical Convergence Zone. On June 12, a broad area of low pressure developed several hundred miles south of Mexico and strengthened into a tropical storm by June 15. The next day, the system stalled unexpectedly within a favorable environment, which led to more intensification than originally anticipated. Early on June 17, Carlotta reached peak intensity with maximum sustained winds of 65 mph (100 km/h) and a minimum central pressure of 997 mbar (29.44 inHg) while located only 30 mi (50 km) south-southeast of Acapulco. The system then began to interact with land and experience wind shear, which resulted in the storm weakening to tropical depression status later in the day. The system weakened to a remnant low early on June 19 and dissipated several hours later.
 Passage 2:Mark first appears in season two, introduced as a highly respected otolaryngologist sub-specialized in plastic surgery and the childhood best friend of neurosurgeon Derek Shepherd (Patrick Dempsey). In his first appearance, he flirts with Meredith Grey, and Derek punches him in the face. Derek explains that Mark had an affair with his wife, Addison (Kate Walsh) while they were living in New York. Mark travels to Seattle, intent on convincing Addison to return with him to New York, but his offer is rejected and Derek declines to renew their friendship. Mark returns during season three at Addison's drunken behest, but she again rejects him once sober. Undeterred, Mark sells his successful private practice (which he previously shared with Derek) and takes over the plastics program at Seattle Grace Hospital. During Meredith's morphine rampage, Mark finds out about his nickname McSteamy which was given to him by her during his first trip to Seattle back when he attempted to get Addison back and earn Derek's friendship back. It is later revealed that Mark has at some point slept with all of Derek's sisters. Mark has a brief fling with Addison's friend, orthopedic surgeon Callie Torres (Sara Ramirez), and develops a friendship with Derek's girlfriend, intern Meredith Grey (Ellen Pompeo). It is revealed that after Derek left New York, Mark and Addison continued their relationship for two months, during which she conceived and aborted his child. Just weeks after moving to Seattle he quickly observes that Derek's true love was Meredith and tries to convince Addison that her marriage with Derek was over. Mark enters into a sixty-day abstinence pact with Addison, agreeing that if they can remain celibate for that time, Addison will give their relationship another chance. Addison ultimately breaks the pact by having sex with intern Alex Karev (Justin Chambers), and soon thereafter departs from Seattle to work in Los Angeles.
 Passage 3:By the early 1890s he had moved away from Bavaria and, with his brother, was working in Duisburg. Together the brothers smuggled subversive anarchist literature into Germany from the Netherlands. Coming under increasing police pressure, and taking his queue from a number of other anarchist comrades in a similar predicament, early in 1892 he fled to the United States of America. On his arrival at New York he met up with the circle around Emma Goldman, Alexander Berkman, and politically like-minded comrades from Germany. Sepp Orter discovered in himself a talent for activism, turning out to have a flair for public speaking. During 1892 he was also the editor of the New York version of , published by the "Radical Workers' Association" ("Radikaler Arbeiter Bund") and the "Autonomy" group which also numbered among its members Josef Peukert. The stay in America was cut short, however. The authorities suspected that Oerter had somehow been involved in Alexander Berkman's attempt to assassinate a wealthy businessman called Henry Clay Frick. Those suspicions appear not to have been entirely unfounded. With financial assistance from Emma Goldman, Sepp Oerter returned to Germany. He travelled via London where he arrived in October, and where the editorial group publishing "Autonomy" gave him a mission to take printed material across Belgium to the German frontier in order to effect a clandestine introduction of the anarchist propaganda to Germany. Sepp Oerter was able to complete his mission with the help of his brother Fritz who had stayed behind when Sepp had escaped to America.

Input: Consider Input: Question: What types of planes did the Australian Flying Corps use the year Holden volunteered for them? Passage 1:"Where the Dream Takes You" is a "tender" pop power ballad with contemporary R&B, soul and lite rock influences, performed in an urban contemporary style. According to the song's official sheet music, published by Walt Disney Music Publishing on Musicnotes.com, "Where the Dream Takes You" is set in signature common time and performed at a moderate tempo of 88 beats per minute in the key of C major. The Disney Song Encyclopedia author Thomas S. Hischak believes that the song's lyrics are "about following your heart to find your true self", which begin "They'll try to hold you back, they will say you're wrong, but they will never understand, no, the journey that you're on." A writer for Barnes & Noble agreed that, thematically, the single "correlates to the film's tale of an inexperienced young adventurer", Milo Thatch, and its diverse cast of supporting characters, all of whom long to follow various dreams of their own as they search for Atlantis. One of its verses reads, "There's something in your soul/That won't be denied/It's the faith to dream that keeps the dream alive/So you still believe and you know you must go", encouraging listeners to follow their dreams despite others' opinions. Lasting a duration of four minutes, AllMusic cites the song's mood as both "earnest" and "mellow"; Mýa performs it using a "sweet vocal", which spans two octaves from G3 to D♭5. Based on a melody heard only briefly during the film, "Where the Dream Takes You" encompasses "soft, contemporary beats" combined with the singer's "dulcet tones" that recall music played in a piano lounge, contrasting with the time period in which the film itself is set. Its production, which has been described as "polished", was handled by Jay Selvester, Robbie Buchanan and Ron Fair.
 Passage 2:The ruins of the Norman Canterbury Castle and St Augustine's Abbey are both open to the public. The medieval St Margaret's Church now houses "The Canterbury Tales", in which life-sized character models reconstruct Geoffrey Chaucer's stories. The Westgate is now a museum relating to its history as a jail. The medieval church of St Alphege became redundant in 1982 but had a new lease of life as the Canterbury Urban Studies Centre, later renamed the Canterbury Environment Centre; the building is used by the King's School. The Old Synagogue, now the King's School Music Room, is one of only two Egyptian Revival synagogues still standing. The city centre contains many timber-framed 16th and 17th century houses, however there are far fewer than there were before the Second World War, as many were damaged during the Baedeker Blitz. Many are still standing, including the "Old Weaver's House" used by the Huguenots. St Martin's Mill is the only surviving mill out of the six known to have stood in Canterbury. It was built in 1817 and worked until 1890; it is now a house conversion. St Thomas of Canterbury Church is the only Roman Catholic church in the city and contains relics of Thomas Becket.
 Passage 3:Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private. He departed for Egypt aboard the transport A29 Suevic on 13 June. Serving as a driver first in the Middle East and then on the Western Front, his mechanical ability and sense of adventure led him to volunteer for the Australian Flying Corps (AFC) in December 1916. After qualifying as a pilot in England, he was commissioned a lieutenant and posted to No. 2 Squadron. Commanded by Major Oswald Watt, No. 2 Squadron's personnel included many former Lighthorsemen, as well as mechanics from the AFC's first combat formation, the Mesopotamian Half Flight. The force trained extensively in England commencing in January 1917, before deploying to the Western Front that September. Holden was involved in the AFC's first day of combat in France; just after noon on 2 October, in the vicinity of Saint-Quentin, he and his wingman engaged a German two-seater that managed to escape.

 Passage 2:Eduard Jan Bomhoff was born on 30 September 1944 in Amsterdam in a Old Catholic family as the son of Jacobus Gerardus Bomhoff a Minister and professor of literature and Riet van Rhijn. The family moved in 1957 to Leiden. Bomhoff attended the Stedelijk Gymnasium Leiden and went to Leiden University. After earning a Master of Economics there he received the Doctor of Philosophy degree in economics from the Erasmus University Rotterdam in 1979. Bomhoff worked as a lecturer in monetary policy there. He earned the rank of professor in 1981, and served as director of the Rochester-Erasmus Executive Master of Business Administration program from 1986 to 1989. He later served as a professor of finance at the Nyenrode Business Universiteit. In addition to his academic career, Bomhoff founded the institute in 1995, an economic research institute designed as an alternative to the official Bureau for Economic Policy Analysis. Bomhoff was also a columnist for the NRC Handelsblad from 1989 until 2002.
 Passage 3:"Don't Be So Hard on Yourself" was written by Jess Glynne, Wayne Hector with its producers Tom Barnes, Peter Kelleher and Ben Kohn, also known as the production team TMS. According to the sheet music published at Musicnotes.com by Universal Music Publishing Group, the song is written in the key of G major (recorded a half-step lower in F major). The song moves in common time at a tempo of 120 beats per minute, with Glynne's vocal range spanning from the low-note of C to the high-note of C. Its instrumentation consists in piano, guitar and violins, filled with strings, glittery synths and emotive vocals. In its bridge, the song also features a "multi-tracked choir and military tattoo drums." It is a dance-pop song with influences of disco, house and soul-pop. Lyrically, it talks about overcoming a broken heart and to not let sadness defeat you. In the chorus, she sings: "Don’t be so hard on yourself, no / Learn to forgive, learn to let go / Everyone trips, everyone falls / So don’t be so hard on yourself, no." When asked about the story behind the song, she elaborated: "When I was meeting my publisher, managers and label and everything was happening for me, I was going through a really hard time. I had my heart broken and I was in a dark place. It was even harder because my dreams were coming true and I had to put a smile on my face every day and power through."
