Problem: The Roman Empire came to dominate the entire Mediterranean basin in a vast empire based on Roman law and Roman legions. It promoted trade, tolerance, and Greek culture. By 300 AD the Roman Empire was divided into the Western Roman Empire based in Rome, and the Eastern Roman Empire based in Constantinople. The attacks of the Germanic peoples of northern Europe led to the Fall of the Western Roman Empire in AD 476, a date which traditionally marks the end of the classical period and the start of the Middle Ages.
Where was the headquarters of the Eastern Roman Empire?
The answer is the following: Constantinople

Problem: Nevertheless, Makdisi has asserted that the European university borrowed many of its features from the Islamic madrasa, including the concepts of a degree and doctorate. Makdisi and Hugh Goddard have also highlighted other terms and concepts now used in modern universities which most likely have Islamic origins, including "the fact that we still talk of professors holding the 'Chair' of their subject" being based on the "traditional Islamic pattern of teaching where the professor sits on a chair and the students sit around him", the term 'academic circles' being derived from the way in which Islamic students "sat in a circle around their professor", and terms such as "having 'fellows', 'reading' a subject, and obtaining 'degrees', can all be traced back" to the Islamic concepts of aṣḥāb ('companions, as of Muhammad'), qirāʼah ('reading aloud the Qur'an') and ijāzah ('licence [to teach]') respectively. Makdisi has listed eighteen such parallels in terminology which can be traced back to their roots in Islamic education. Some of the practices now common in modern universities which Makdisi and Goddard trace back to an Islamic root include "practices such as delivering inaugural lectures, wearing academic robes, obtaining doctorates by defending a thesis, and even the idea of academic freedom are also modelled on Islamic custom." The Islamic scholarly system of fatwá and ijmāʻ, meaning opinion and consensus respectively, formed the basis of the "scholarly system the West has practised in university scholarship from the Middle Ages down to the present day." According to Makdisi and Goddard, "the idea of academic freedom" in universities was also "modelled on Islamic custom" as practised in the medieval Madrasa system from the 9th century. Islamic influence was "certainly discernible in the foundation of the first deliberately planned university" in Europe, the University of Naples Federico II founded by Frederick II, Holy Roman Emperor in 1224.
What institutions have been considered to take some its ideas from madaris?
The answer is the following: European university

Problem: Theories given for the success of Southerners on Idol have been: more versatility with musical genres, as the Southern U.S. is home to several music genre scenes; not having as many opportunities to break into the pop music business; text-voting due to the South having the highest percentage of cell-phone only households; and the strong heritage of music and singing, which is notable in the Bible Belt, where it is in church that many people get their start in public singing. Others also suggest that the Southern character of these contestants appeal to the South, as well as local pride. According to season five winner Taylor Hicks, who is from the state of Alabama, "People in the South have a lot of pride ... So, they're adamant about supporting the contestants who do well from their state or region."
Where is Taylor Hicks from?
The answer is the following: Alabama

Problem: Machine vision systems often require bright and homogeneous illumination, so features of interest are easier to process. LEDs are often used for this purpose, and this is likely to remain one of their major uses until the price drops low enough to make signaling and illumination uses more widespread. Barcode scanners are the most common example of machine vision, and many low cost products use red LEDs instead of lasers. Optical computer mice are an example of LEDs in machine vision, as it is used to provide an even light source on the surface for the miniature camera within the mouse. LEDs constitute a nearly ideal light source for machine vision systems for several reasons:
LEDs are often used for what type of systems?
The answer is the following:
Machine vision
