PROBLEM: Passage: "Halo" was composed by Ryan Tedder, lead vocalist of OneRepublic, together with Evan "Kidd" Bogart and Beyoncé. In an interview for HitQuarters, Kidd narrated the events that led to writing the song. OneRepublic canceled their tour after Tedder had broken his Achilles tendon and had undergone surgery. The following day, the band sent Tedder to Los Angeles. There, he and Kidd were socializing when Tedder expressed his desire to write a song. Kidd was initially opposed to the idea because Tedder was supposed to be recuperating, but the pair went to Tedder's studio. During the writing sessions, singer Ray LaMontagne was the primary inspiration for "Halo". Kidd suggested they create a song in the style of LaMontagne's "Shelter" for Beyoncé and her husband Jay-Z, and proposed the title "Halo" after hearing Tedder play "angelic" chords. They wrote the song in three hours.According to Simon Cowell, owner of the music production company Syco Entertainment, Bogart and Tedder intended "Halo" for his client, singer Leona Lewis, who could not record the song because of her tight schedule. Cowell was upset that Beyoncé chose to record the song. David Balls, editor of the British media website Digital Spy, asked Tedder during an interview whether "Halo" had initially been written for Lewis. Tedder answered that he had only tentatively offered the track to Lewis, after Beyoncé waited a long time before recording it. He commented:
There was this huge scandal that originally "Halo" was meant to go to Leona. That was never the case ... That song was written for Beyoncé. What happened was that Beyoncé waited long enough to record that song ... I thought this would be a brilliant first single for Leona, which it would have ... What I did was foolishly say to Leona's camp, "I have it on hold for another A-list artist and I'm pretty sure they'll take it, but if they don't, I just want to know if you like it enough to consider it". I sent it to them and they flipped on it. They loved it and instantly said they wanted to do it. I was like, "Wait, wait, wait, no, it's not free yet!". 
Question: What is the first name of the person who broke his Achilles tendon?

SOLUTION: Ryan.

PROBLEM: Passage: The United States Exploring Expedition led by Lieutenant Charles Wilkes was tasked with a vast survey of the Pacific Ocean starting in 1838. In September 1840 they arrived in Honolulu, where repairs to the ships took longer than expected. Wilkes decided to spend the winter in Hawaii and take the opportunity to explore its volcanoes while waiting for better weather to continue the expedition. King Kamehameha III assigned American medical missionary Dr. Gerrit P. Judd to the expedition as a translator.Wilkes sailed to Hilo on the island of Hawaiʻi and decided to climb Mauna Loa first, since it looked easier than Mauna Kea. On December 14 he hired about 200 porters, but after he left he realized only about half the equipment had been taken, so he had to hire more Hawaiians at higher pay. When they reached Kīlauea after two days, their guide Puhano headed off to the established ʻAinapō Trail. Wilkes did not want to head back downhill so he blazed his own way through dense forest directed by a compass. The Hawaiians were offended by the waste of sacred trees which did not help morale. At about 6,000 feet (1,800 m) elevation they established a camp called "Sunday Station" at the edge of the forest.
Two guides joined them at Sunday Station: Keaweehu, "the bird-catcher" and another whose Hawaiian name is not recorded, called "ragsdale". Although Wilkes thought he was almost to the summit, the guides knew they were less than halfway up. Since there was no water at Sunday Station, porters had to be sent back ten miles (16 km) to a lava tube on ʻAinapō Trail which had a known supply. After an entire day replenishing stocks, they continued up to a second camp they called "Recruiting Station" at about 9,000 feet (2,700 m) elevation. After another full day's hike they established "Flag Station" on December 22, and by this time were on the ʻAinapō Trail. Most of the porters were sent back down to get another load. 
Question: What is the name of the third station that was established on the hike by United States Exploring Expedition?

SOLUTION: Flag Station.

PROBLEM: Passage: The fall of the inner German border came rapidly and unexpectedly in November 1989, along with the fall of the Berlin Wall. Its integrity had been fatally compromised in May 1989 when the Hungarian government began dismantling its border fence with Austria. The government was still notionally Communist but planned free elections and economic reform as part of a strategy of "rejoining Europe" and reforming its struggling economy.Opening the Hungarian border with Austria was essential to this effort. Hungary was at that time a popular tourist destination for East Germans; West Germany had secretly offered a much-needed hard currency loan of DM 500 million ($250 million) in return for allowing citizens of the GDR to freely emigrate. Pictures of the barbed-wire fences being taken down were transmitted into East Germany by West German television stations. This prompted a mass exodus by hundreds of thousands of East Germans, which began in earnest in September 1989. In addition to those crossing the Hungarian border, tens of thousands of East Germans scaled the walls of the West German embassies in Prague, Warsaw and Budapest, where they were regarded as "German citizens" by the federal government, claiming "asylum".Czechoslovakia's hardline communist government agreed to close its border with East Germany to choke off the exodus. The closure produced uproar across East Germany and the GDR government's bid to humiliate refugees by expelling them from the country in sealed trains backfired disastrously. Torn-up identity papers and East German passports littered the tracks as the refugees threw them out of the windows. When the trains passed through Dresden, 1,500 East Germans stormed the main railway station in an attempt to board. Dozens were injured and the station concourse was virtually destroyed.The small pro-democracy Monday demonstrations soon swelled into crowds of hundreds of thousands of people in cities across East Germany. The East German leadership considered using force but ultimately backed down, lacking support from the Soviet Union for a violent Tiananmen Square-style military intervention. Reformist members of the East German Politbüro sought to rescue the situation by forcing the resignation of the hardline Party chairman Erich Honecker, replacing him in October 1989 with the marginally less hardline Egon Krenz.The new government sought to appease the protesters by reopening the border with Czechoslovakia. This, however, merely resulted in the resumption of the mass exodus through Hungary via Czechoslovakia. On 8 November 1989, with huge demonstrations continuing across the country, the entire Politbüro resigned and a new, more moderate Politbüro was appointed under Krenz's continued leadership. 
Question: What is the full name of the person who replaced Erich Honecker?

SOLUTION:
Egon Krenz.
