Problem: Hellenistic period:

The Hellenistic period covers the period of ancient Greek (Hellenic) history and Mediterranean history between the death of Alexander the Great in 323 BC and the emergence of the Roman Empire as signified by the Battle of Actium in 31 BC and the subsequent conquest of Ptolemaic Egypt the following year. At this time, Greek cultural influence and power was at its peak in Europe, Africa and Asia, experiencing prosperity and progress in the arts, exploration, literature, theatre, architecture, music, mathematics, philosophy, and science. For example, competitive public games took place, ideas in biology, and popular entertainment in theaters. It is often considered a period of transition, sometimes even of decadence or degeneration, compared to the enlightenment of the Greek Classical era. The Hellenistic period saw the rise of New Comedy, Alexandrian poetry, the Septuagint and the philosophies of Stoicism and Epicureanism. Greek Science was advanced by the works of the mathematician Euclid and the polymath Archimedes. The religious sphere expanded to include new gods such as the Greco-Egyptian Serapis, eastern deities such as Attis and Cybele and the Greek adoption of Buddhism.

Problem: In Congregational and Presbyterian churches which profess a traditionally Calvinist or Reformed theology there are differing views regarding present-day continuation or cessation of the gifts (charismata) of the Spirit. Generally, however, Reformed charismatics distance themselves from renewal movements with tendencies which could be perceived as overemotional, such as Word of Faith, Toronto Blessing, Brownsville Revival and Lakeland Revival. Prominent Reformed charismatic denominations are the Sovereign Grace Churches and the Every Nation Churches in the USA, in Great Britain there is the Newfrontiers churches and movement, which leading figure is Terry Virgo.
Who heads the Newfrontiers movement?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the context of relativity, mass is not an additive quantity, in the sense that one can add the rest masses of particles in a system to get the total rest mass of the system. Thus, in relativity usually a more general view is that it is not the sum of rest masses, but the energymomentum tensor that quantifies the amount of matter. This tensor gives the rest mass for the entire system. "Matter" therefore is sometimes considered as anything that contributes to the energymomentum of a system, that is, anything that is not purely gravity. This view is commonly held in fields that deal with general relativity such as cosmology. In this view, light and other massless particles and fields are part of matter.
What does gravity contribute to in a system?
A: unanswerable

Context and question: Around the sixth century AD, a tribe of Slavs arrived in a portion of Central Europe. According to legend they were led by a hero named Cech, from whom the word "Czech" derives. The ninth century brought the state of Great Moravia, whose first ruler (Rastislav of Moravia) invited Byzantine ruler Michael III to send missionaries in an attempt to reduce the influence of East Francia on religious and political life in his country. These missionaries, Constantine and Methodius, helped to convert the Czechs from traditional Slavic paganism to Christianity and established a church system. They also brought the Glagolitic alphabet to the West Slavs, whose language was previously unwritten. This language, later known as Proto-Czech, was beginning to separate from its fellow West Slavic hatchlings Proto-Slovak, Proto-Polish and Proto-Sorbian. Among other features, Proto-Czech was marked by its ephemeral use of the voiced velar fricative consonant (//) and consistent stress on the first syllable.
Why did Cech send out missionaries?
Answer: unanswerable

Question: More recent Lancashire-born composers include Hugh Wood (1932- Parbold), Sir Peter Maxwell Davies (1934-, Salford), Sir Harrison Birtwistle (1934-, Accrington), Gordon Crosse (1937-, Bury),John McCabe (1939-2015, Huyton), Roger Smalley (1943-2015, Swinton), Nigel Osborne (1948-, Manchester), Steve Martland (1954-2013, Liverpool), Simon Holt (1958-, Bolton) and Philip Cashian (1963-, Manchester). The Royal Manchester College of Music was founded in 1893 to provide a northern counterpart to the London musical colleges. It merged with the Northern College of Music (formed in 1920) to form the Royal Northern College of Music in 1972.
Is there an answer to this question: In what year did Harrison Birtwistle receive the Sir title?

Answer: unanswerable

One of the more prominent contestants this year was Chris Medina, whose story of caring for his brain-damaged fiancee received widespread coverage. Medina was cut in the Top 40 round. Casey Abrams, who suffers from ulcerative colitis, was hospitalized twice and missed the Top 13 result show. The judges used their one save on Abrams on the Top 11, and as a result this was the first season that 11 finalists went on tour instead of 10. In the following week, Naima Adedapo and Thia Megia were both eliminated the following week.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which contestant had a fiance that had suffered brain damage?
Ah, so..
Chris Medina
