The answer to the question: What are the name of the people that attacked Constantinople? is inside the article: The Arabs, now firmly in control of Syria and the Levant, sent frequent raiding parties deep into Asia Minor, and in 674678 laid siege to Constantinople itself. The Arab fleet was finally repulsed through the use of Greek fire, and a thirty-years' truce was signed between the Empire and the Umayyad Caliphate. However, the Anatolian raids continued unabated, and accelerated the demise of classical urban culture, with the inhabitants of many cities either refortifying much smaller areas within the old city walls, or relocating entirely to nearby fortresses. Constantinople itself dropped substantially in size, from 500,000 inhabitants to just 40,00070,000, and, like other urban centres, it was partly ruralised. The city also lost the free grain shipments in 618, after Egypt fell first to the Persians and then to the Arabs, and public wheat distribution ceased.The void left by the disappearance of the old semi-autonomous civic institutions was filled by the system called theme, which entailed dividing Asia Minor into "provinces" occupied by distinct armies that assumed civil authority and answered directly to the imperial administration. This system may have had its roots in certain ad hoc measures taken by Heraclius, but over the course of the 7th century it developed into an entirely new system of imperial governance. The massive cultural and institutional restructuring of the Empire consequent on the loss of territory in the 7th century has been said to have caused a decisive break in east Mediterranean Romanness and that the Byzantine state is subsequently best understood as another successor state rather than a real continuation of the Roman Empire., can you guess it ?

The answer to the question: What if the full name of the critic who praised the "twin-guitar attack" on the album? is inside the article: Sydney Morning Herald commentator Bernard Zuel described Dream Days at the Hotel Existence as Powderfinger's first dull album, noting that on numerous songs "It promises to become exciting but never quite gets there." He complained that most of the songs were uneventful, or uninspiring, and that they do not "lift you as a listener." PerthNow's Jay Hanna disagreed, claiming the album was "rippling with emotions". He said the album contained some "incredible moments", praising "Head Up in the Clouds", and calling "Nobody Sees" "Powderfinger at their devastating best", while giving the album four stars.Cameron Adams of Herald Sun HiT stated that the album contained no new directions for the band, and was highly consistent. He noted that the album contained less "rough edges and attitude" than predecessor Vulture Street, and likening the album more to Odyssey Number Five. Sputnikmusic's James Bishop agreed, claiming the band should be concerned by the "lack of experimentation or ambition" on the album. He again stated that the album was consistent, noting that "there actually isn't a bad song present". The review, which gave the album three and a half stars, commented that it seemed the band were trying to move towards the bluegrass genre, and "edging their way into the adult-contemporary section" of a music store, something they had not shown on their previous works.AllMusic's Clayton Bolger drew comparisons to Internationalist in his review, which gave the album 3 and a half stars. He said the album contained "all the trademarks of classic Powderfinger", praising Fanning's vocals, Middleton and Haug's "twin-guitar attack", Collins' basslines and Coghill's "powerhouse drum work". While praising "I Don't Remember" as an excellent anthem, and "Surviving" for containing "a sonic blast of rock", he was critical of "Lost and Running", which he said felt "tired and sluggish", while "Ballad of a Dead Man" was described as "tedious"., can you guess it ?

The answer to the question: What is the name of the person who speaks to the man from the United States briefly in the park? is inside the article: The Best Two Years portrays the experience of four missionaries of The Church of Jesus Christ of Latter-day Saints living in the same apartment in Haarlem in the Netherlands. The movie begins with Elder Rogers finding out that his new companion will be a "greenie", a newly trained missionary fresh from the Missionary Training Center. He and the other two missionaries that reside in the same apartment, Elder Johnson and Elder Van Pelt, go to the train station to meet the new elder. Elder Rogers finds out that the new missionary, Elder Calhoun, is exactly what he had jokingly predicted his new companion would be like. Elder Rogers used to be an excellent missionary, until his girlfriend married one of his former mission companions. That is why he and the other two missionaries residing in the same apartment are surprised that the mission president has assigned him to be the trainer (first companion and mentor) to a missionary new to the mission. The new missionary, Elder Calhoun, tackles mission work with unbounded enthusiasm. He attempts to talk to anyone although he has little knowledge of the Dutch language. Despite his poor Dutch, he continues to have an eager attitude. Fortunately for him, he soon encounters a man from the United States that speaks English. They speak briefly in the park before the man goes off with his girlfriend. Later, when he encounters the same man in a market, Calhoun gives him a Dutch Book of Mormon with his telephone number. Despite what the other three missionaries expect, the man does call and asks for Calhoun., can you guess it ?
