QUES: The traditional parish system persisted until the Reconstruction Era, when counties were imposed.[citation needed] Nevertheless, traditional parishes still exist in various capacities, mainly as public service districts. When the city of Charleston was formed, it was defined by the limits of the Parish of St. Philip and St. Michael, now also includes parts of St. James' Parish, St. George's Parish, St. Andrew's Parish, and St. John's Parish, although the last two are mostly still incorporated rural parishes.

What era brought counties to South Carolina?
What is the answer?
ANS: Reconstruction Era

QUES: Sahih al-Bukhari narrates Muhammad describing the revelations as, "Sometimes it is (revealed) like the ringing of a bell" and Aisha reported, "I saw the Prophet being inspired Divinely on a very cold day and noticed the sweat dropping from his forehead (as the Inspiration was over)." Muhammad's first revelation, according to the Quran, was accompanied with a vision. The agent of revelation is mentioned as the "one mighty in power", the one who "grew clear to view when he was on the uppermost horizon. Then he drew nigh and came down till he was (distant) two bows' length or even nearer." The Islamic studies scholar Welch states in the Encyclopaedia of Islam that he believes the graphic descriptions of Muhammad's condition at these moments may be regarded as genuine, because he was severely disturbed after these revelations. According to Welch, these seizures would have been seen by those around him as convincing evidence for the superhuman origin of Muhammad's inspirations. However, Muhammad's critics accused him of being a possessed man, a soothsayer or a magician since his experiences were similar to those claimed by such figures well known in ancient Arabia. Welch additionally states that it remains uncertain whether these experiences occurred before or after Muhammad's initial claim of prophethood.
What measure of distance described the nearness of the Angel's approach to Mohammad?

ANS: two bows' length

Data compression can be viewed as a special case of data differencing: Data differencing consists of producing a difference given a source and a target, with patching producing a target given a source and a difference, while data compression consists of producing a compressed file given a target, and decompression consists of producing a target given only a compressed file. Thus, one can consider data compression as data differencing with empty source data, the compressed file corresponding to a "difference from nothing." This is the same as considering absolute entropy (corresponding to data compression) as a special case of relative entropy (corresponding to data differencing) with no initial data.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What means producing a compressed file given no initial data?
Ah, so.. unanswerable

Question: Many students are involved in community service in one form or another. Annual events include Dance Marathon, a thirty-hour event that raised more than a million dollars for charity in 2011; and Project Pumpkin, a Halloween celebration hosted by the Northwestern Community Development Corps (NCDC) to which more than 800 local children are invited for an afternoon of games and sweets. NCDC's work is to connect hundreds of student volunteers to some twenty volunteer sites in Evanston and Chicago throughout the year. Many students have assisted with the Special Olympics and have taken alternative spring break trips to hundreds of service sites across the United States. Northwestern students also participate in the Freshman Urban Program, a program for students interested in community service. A large and growing number of students participate in the university's Global Engagement Summer Institute (GESI), a group service-learning expedition in Asia, Africa, or Latin America, in conjunction with the Foundation for Sustainable Development. Several internationally recognized non-profit organizations have originated at Northwestern including the World Health Imaging, Informatics and Telemedicine Alliance, a spin-off from an engineering student's honors thesis.
Try to answer this question if possible: What is the name of the university's group service-learning expedition in Asia, Africa or Latin America?
Answer:
Global Engagement Summer Institute
