In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Question: Which location sits higher above sea level, the modern capital of Armenia or the location where the fortress was found in 782? Passage:The name Armenia was given to the country by the surrounding states, and it is traditionally derived from Armenak or Aram (the great-grandson of Haik's great-grandson, and another leader who is, according to Armenian tradition, the ancestor of all Armenians). In the Bronze Age, several states flourished in the area of Greater Armenia, including the Hittite Empire (at the height of its power), Mitanni (South-Western historical Armenia), and Hayasa-Azzi (1600–1200 BC). Soon after the Hayasa-Azzi were the Nairi (1400–1000 BC) and the Kingdom of Urartu (1000–600 BC), who successively established their sovereignty over the Armenian Highland. Each of the aforementioned nations and tribes participated in the ethnogenesis of the Armenian people. Yerevan, the modern capital of Armenia, dates back to the 8th century BC, with the founding of the fortress of Erebuni in 782 BC by King Argishti I at the western extreme of the Ararat plain. Erebuni has been described as "designed as a great administrative and religious centre, a fully royal capital."

Question: What country was the university Sadeq Tabatabaei got his doctorate from located in? Passage:In 1961, Sadegh Tabatabai went to Aachen to study biochemistry and later received his doctorate from the University of Bochum. While in Aachen, he organized a student group that campaigned against Shah Mohammad Reza Pahlavi. In 1967, he handled Ulrike Meinhof material about Iran, which was used in a famous column in Konkret magazine opposing the Shah's visit to West Germany that year. Tabatabai gave a speech at the grave of Benno Ohnesorg, an unarmed university student who was shot during a demonstration against the Shah's visit to the Deutsche Oper in Berlin by Karl-Heinz Kurras, a police officer later discovered to be an agent of the East German secret police, the Stasi.

Question: Which city had a higher crime rate before the "pod" system was enacted; Tucson, or Charlotte? Passage:Once the S-curve is established, the committee must place the teams throughout the four regions. They were originally referred to as East, Mideast, Midwest, and West. In 1985, the Mideast designation became the Southeast, and later the South Regional in 1998. The women's tournament continued to use the Mideast terminology through 2004. In 2004, the NCAA started to identify the men's regions only by the city in which the regional semifinals and finals were played, with the same change being made for the women's tournament in 2005. The NCAA reverted to the East/South/Midwest/West designations for the men's tournament starting in 2007, but continues to designate women's regionals by their cities. Typically the cities selected will be spread throughout the country and conform roughly to the old geographic distinctions. While the regions are named for certain cities, the first and second round games are played in different cities which need not be anywhere near the regional finals. In 2005 the Austin, Texas men's regional was fed by games in Indianapolis, Indiana; Tucson, Arizona; Charlotte, North Carolina; and Worcester, Massachusetts. This is due to the "pod" system enacted before the 2002 tournament to minimize travel for as many teams as possible, especially in the early rounds. Any team may be sent to any region and any pod, although the tournament does try to keep teams, especially the top-seeded teams, closer to home. However, in 2004, Pittsburgh played its first two tournament games in Milwaukee and not in Buffalo or Columbus, cities to which it was closer. This was done to keep a lower-seeded team, the Wisconsin Badgers, close to its campus. Similarly, two east-coast teams, Maryland and Syracuse, traveled to Denver, where their opening round opponents were BYU and UTEP, both of which were geographically closer to Denver. In addition, in 2009, Kansas and West Virginia, the two higher seeds, traveled to Minneapolis to play their opponents North Dakota State and Dayton, although Dayton and North Dakota State are geographically closer to Minneapolis than Kansas and West Virginia. To make matters worse for both latter teams, Kansas City (Kansas) and Greensboro NC (West Virginia) were both 1st-2nd round sites that year.
