Input: Consider Input: Question: Who were the intial anchors for the KTLA Morning News? Passage 1:The film opens before the declaration of the Indo-Pakistani War of 1971. At a forward operating airbase, Indian Air Force Wing Commander Anand "Andy" Bajwa (Jackie Shroff), setting his stopwatch, waits for the air raid siren to go. As the siren goes, he sprints towards his MiG-21, armed, fuelled and ready for takeoff. Bajwa and his air force wingmen soon take off to an unknown airbase in Rajasthan. Once there, he is briefed by his superiors that he and his squadron are assigned to the Jaisalmer sector and have to fly the outdated and day fighter Hawker Hunter Ground attack planes (with no night vision capabilities) to support the Indian Army. He is soon joined by his brother-in-arms army Major Kuldip Singh Chandpuri (Sunny Deol) as they meet on a courier flight and speak about the possibility of the opening of the Western front in light of the East Pakistan conflict. Kuldip takes up command of a company of the 23rd Battalion Punjab Regiment, arguing the light defence being assigned to the military post of Longewala. He meets his second-in-command 2nd Lieutenant Dharamveer Bhan (Akshaye Khanna) (who happens to be the son of a 1965 Indo-Pakistani War veteran who was killed during that war) and the Company JCO Naib Subedar Mathura Das (Sudesh Berry). The company moves to a remote outpost in the deserts of Rajasthan and begin to expand the rudimentary Border Security Force (BSF) post and does the observation of the area up to the international border with Pakistan. They meet the post's BSF Assistant Commandant Bhairon Singh (Sunil Shetty), a deeply patriotic man who expresses his love for the desert.
Passage 2:In 1944, Argentia served as one of the two stopover bases for the refuelling, maintenance, and crew changes of the six United States Navy (USN) K-class blimps that made the first transatlantic crossings of non-rigid airships. Blimps K-123 and K-130 from USN Blimp Squadron 14 (also known as ZP-14, Blimpron 14, or "The Africa Squadron") left South Weymouth Naval Air Station in Massachusetts on 28 May 1944 and landed at Argentia about 16 hours later. The two K-ships then flew for approximately 22 hours to Lages Field on Terceira Island in the Azores, the second stopover base for the transatlantic flights. The last leg was a ~20-hour flight to the squadron's final destination with Fleet Air Wing (FAW) 15 at Port Lyautey, French Morocco (now Kenitra, Morocco). Blimps K-123 and K-130 were followed by K-109 and K-134 then K-112 and K-101 which left South Weymouth on 11 and 27 June, respectively, in 1944. These six blimps initially conducted nighttime anti-submarine warfare operations to complement the daytime missions flown by FAW-15 aircraft (PBYs and PB4Y-2) using magnetic anomaly detection to locate U-boats in the relatively shallow waters around the Strait of Gibraltar. Later, ZP-14 K-ships conducted minespotting and minesweeping operations in key Mediterranean ports and various escort missions including that of the convoy carrying Franklin Roosevelt and Winston Churchill to the Yalta Conference in early 1945. In late April 1945, K-89 and K-114 left NAS Weeksville (now Coast Guard Air Station Elizabeth City) in North Carolina and flew a southern route to NAS Bermuda, the Azores, and Port Lyautey, where they arrived on 1 May 1945.
Passage 3:In March 1991, KTLA was the first station to air the infamous video of Rodney King's beating by three Los Angeles police officers, whose eventual acquittal sparked rioting within the city in 1992. In July 1991, KTLA debuted the Los Angeles market's first live, local morning two-hour newscast, the KTLA Morning News, to compete with the network morning shows on KABC-TV (channel 7), KCBS-TV (channel 2) and KNBC (which each started at 7:00a.m., as KTLA's program initially did). The program suffered from low ratings at first; however, the ability to cover breaking news live (as opposed to the network morning programs, which were aired on a three-hour tape delay) attracted more viewers to the program. As time went on, the Morning News has enjoyed great ratings success, generally ranking number one in its main 7:009:00a.m. time period. The program's success spawned rival KTTV to launch its own morning newscast, Good Day L.A., in 1993. From 1994 to 1995, the station aired gavel to gavel coverage of the O.J. Simpson trial anchored by Marta Waller (this coverage was rebroadcast by other stations such as Portland, Oregon WB affiliate [and future Tribune sister station] KWBP (now KRCW-TV)).

Input: Consider Input: Question: Which college where Harben was educated has the highest enrollment? Passage 1:The towers were designed as framed tube structures, giving tenants open floor plans, unobstructed by columns or walls. The framed tube design was introduced by Bangladeshi-American structural engineer Fazlur Rahman Khan in the 1960s. The design was accomplished by using many closely spaced perimeter columns, providing much of the structure's strength, with the gravity load shared with the core columns. The elevator system, which made use of sky lobbies and a system of express and local elevators, allowed substantial floor space to be used for office purposes by making the structural core smaller. The design and construction of the towers involved many other innovative techniques, such as wind tunnel experiments and the slurry wall for digging the foundation. Yamasaki also incorporated elements of Islamic architecture in the building's design, having previously designed Saudi Arabia's Dhahran International Airport with the Saudi Binladin Group.
Passage 2:Beagle is a crater lying within the Margaritifer Sinus quadrangle (MC-19) portion of the planet Mars, the crater is one of multiple topographical depressions within the Meridiani Planum extraterrestrial plain, which was explored by the Opportunity rover. It was located by the rover in images taken on sol 855 (June 20, 2006), 310 metres (1,107ft) away. It is on the edge of the much larger ejecta blanket surrounding the crater Victoria, named the Victoria Annulus. This impact crater was named in honor of HMS Beagle of the Royal Navy, ordered in February 1817, which carried Charles Darwin on his voyage round the world.
Passage 3:He was the son of Henry Andrade Harben and the grandson of Sir Henry Harben who founded Prudential Assurance, Harben was educated at Eton College and Magdalen College, Oxford, before qualifying as a barrister. He married Agnes Helen Bostock. He stood unsuccessfully for the Conservative Party in Eye at the 1900 general election, but by 1902 had switched his affiliation to the Liberal Party. He stood for the Liberal Party in Worcester at the 1906 general election. Although he lost the election, he petitioned the election court on the grounds that supporters of the winner, George Henry Williamson, had engaged in widespread bribery. He won the case, but the seat was left vacant until a by-election in 1908, and the local Liberal Party adopted a new candidate. Harben next stood in Portsmouth at the December 1910 general election, but came bottom of the poll.

Input: Consider Input: Question: How many copies did the second live album of Aventura sell? Passage 1:The Bachata #1's series is a collection of compilations of various artists centered on the genre of bachata. The first chapter in the series was released in 2007. A third volume, Bachata #1's, Vol. 3 was released in 2010 in the United States. Bachata #1's, Vol. 2 was released on August 12, 2008. "Mi Corazoncito", written by Anthony "Romeo" Santos and performed by Aventura, was released as the third and final single from the group's second live album, K.O.B. Live (2006). The song peaked at number fifteen on the Billboard Latin Pop Songs and number two on the Billboard Latin Songs charts, topping both the Billboard Tropical Songs and Billboard Latin Rhythm Songs charts, while an additional live version peaked at number ten on the Billboard Tropical Songs chart. The bachata-infused-R&B number, has been named one of their biggest hits along with "Los Infieles", "Un Beso", and "El Perdedor" among others. Xtreme's "Mientes" is originally from the duo's second studio album Haciendo Historia (2006), which also featured the gorup's R&B-leaning hit single "Shorty, Shorty". Puerto Rican Latin pop singer Luis Fonsi performs "Con Las Manos Vacias", a track exclusive to this release. "Tengo Un Amor" was written by Toby Love with additional composition by Edwin Perez who also handled production for the song. The song was written with Spanglish lyrics combining crunk hip hop with bachata. David Jefferies, while reviewing the parent album, called the song "an incredibly smooth, lush, and glittery ballad" while listing the song as a selected "Allmusic Pick". According to Billboard, the original version of the song is a "straightforward bachata song" while the remix, which is included on this release, with R.K.M & Ken-Y, known then as Rakim & Ken-Y provides "urban street cred".
Passage 2:Tony met Deep Purple in the early 1970s, when the last recording of Ashton, Gardner and Dyke was a collaboration with keyboardist Jon Lord on the soundtrack for a b-movie called The Last Rebel. In the meantime, Ashton had appeared on Jon Lord's first solo album Gemini Suite in 1971. In 1973, Ashton joined the group Family for their last album and tour. That same year, he and David Coverdale and Glenn Hughes were guest vocalists on Jon Lord's second album Windows. Tony became close friends with Jon Lord. In the summer of 1974, during a break in Purple's busy touring schedule, Tony Ashton and Jon Lord recorded their album First of the Big Bands. This project was launched with a gig at the London Palladium the same year and the BBC taped a special live appearance at Golders Green Hippodrome in London. The album of this show is a tour-de-force groovy, rhythm and blues, boogie piano and Hammond organ, big band fest. Tony also contributed to Roger Glover's Butterfly Ball project. In these years, Ashton and Lord found a second home in Zermatt, an alpine resort in Switzerland, sometimes to ski, but more often to offer giant and brilliant non-profit gigs in a unique complex (one hotel-two night-clubs-two restaurants and four pubs) called "Hotel Post" which was run by American-born Karl Ivarsson. Ashton managed to come to the place almost until his death, and Jon has been a regular visitor until his death even if the "(in)famous" hotel did not exist anymore.
Passage 3:Ross married Bertha (Bee) Halley Horecker, a singer-musician and daughter of Ross's Chicago neighbors, in 1931, received a National Research Council Fellowship for 1932, and worked as a National Research Council postdoctoral fellow at California Institute of Technology with Eric Temple Bell until 1933. Ross moved back to Chicago and led the mathematics department at an experimental school started by Ph.D.s during the Great Depression, People's Junior College, where he also taught physics. Ross became an assistant professor at St. Louis University in 1935 and stayed for about 11 years. In an interview, he said he advocated for a student who became the first black woman in the South to receive a master's degree in mathematics. This exception led the university to admit black students despite the idea's widespread unpopularity. During World War II, Ross served as a research mathematician for the U.S. Navy. He befriended Hungarian mathematician Gabor Szego while in St. Louis, who recommended Ross for a 1941 Brown University summer school that prepared young scientists to assist in the war, a program Ross attended. He occasionally worked on proximity fuzes for Stromberg-Carlson's laboratory from 1941 to 1945 before accepting a position as head of University of Notre Dame's mathematics department in 1946. He set out to change the school's research climate by inviting distinguished mathematicians including Paul Erdos, whom Ross made a full professor.
