Please answer this: I know that the answer to the question "What surrounds the old centre?" is in "Another landmark is the old centre and the canal structure in the inner city. The Oudegracht is a curved canal, partly following the ancient main branch of the Rhine. It is lined with the unique wharf-basement structures that create a two-level street along the canals. The inner city has largely retained its Medieval structure, and the moat ringing the old town is largely intact. Because of the role of Utrecht as a fortified city, construction outside the medieval centre and its city walls was restricted until the 19th century. Surrounding the medieval core there is a ring of late 19th- and early 20th-century neighbourhoods, with newer neighbourhoods positioned farther out. The eastern part of Utrecht remains fairly open. The Dutch Water Line, moved east of the city in the early 19th century required open lines of fire, thus prohibiting all permanent constructions until the middle of the 20th century on the east side of the city.".

Please answer this: I know that the answer to the question "Which of the following has the fewest employees: Madonna, the Vatican, or Pepsi?" is in "Academics noted that with her videos, Madonna was subtly reversing the usual role of male as the dominant sex. This symbolism and imagery was probably the most prevalent in the music video for "Like a Prayer". The video included scenes of an African-American church choir, Madonna being attracted to a statue of a black saint, and singing in front of burning crosses. This mix of the sacred and the profane upset the Vatican and resulted in the Pepsi commercial withdrawal. In 2003, MTV named her "The Greatest Music Video Star Ever" and said that "Madonna's innovation, creativity and contribution to the music video art form is what won her the award."".

Please answer this: I know that the answer to the question "What does royalty rule over?" is in "The most important source after Polybius is Diodorus Siculus who wrote his Bibliotheca historica between 60 and 30 BCE and reproduced some important earlier sources such as Hieronymus, but his account of the Hellenistic period breaks off after the battle of Ipsus (301). Another important source, Plutarch's (c.50c.120) Parallel Lives though more preoccupied with issues of personal character and morality, outlines the history of important Hellenistic figures. Appian of Alexandria (late first century CE-before 165 CE) wrote a history of the Roman empire that includes information of some Hellenistic kingdoms.". Can you tell me what it is?
