Here is a question about this article: Greek-speaking communities of the Hellenized East were instrumental in the spread of early Christianity in the 2nd and 3rd centuries, and Christianity's early leaders and writers (notably St Paul) were mostly Greek-speaking, though generally not from Greece itself. The New Testament was written in Greek, and some of its sections (Corinthians, Thessalonians, Philippians, Revelation of St. John of Patmos) attest to the importance of churches in Greece in early Christianity. Nevertheless, much of Greece clung tenaciously to paganism, and ancient Greek religious practices were still in vogue in the late 4th century AD, when they were outlawed by the Roman emperor Theodosius I in 391-392. The last recorded Olympic games were held in 393, and many temples were destroyed or damaged in the century that followed. In Athens and rural areas, paganism is attested well into the sixth century AD and even later. The closure of the Neoplatonic Academy of Athens by the emperor Justinian in 529 is considered by many to mark the end of antiquity, although there is evidence that the Academy continued its activities for some time after that. Some remote areas such as the southeastern Peloponnese remained pagan until well into the 10th century AD.
What is the answer to this question: The Olympics were last held in ancient Greece in what year? 
****
So... 393


Here is a question about this article: In 1933, the Orthodox Church of Greece officially declared that being a Freemason constitutes an act of apostasy and thus, until he repents, the person involved with Freemasonry cannot partake of the Eucharist. This has been generally affirmed throughout the whole Eastern Orthodox Church. The Orthodox critique of Freemasonry agrees with both the Roman Catholic and Protestant versions: "Freemasonry cannot be at all compatible with Christianity as far as it is a secret organisation, acting and teaching in mystery and secret and deifying rationalism."
What is the answer to this question: Freemasonry cannot be compatible with what according to the Orthodox Church?
****
So... Christianity


Here is a question about this article: The onset of infrared is defined (according to different standards) at various values typically between 700 nm and 800 nm, but the boundary between visible and infrared light is not precisely defined. The human eye is markedly less sensitive to light above 700 nm wavelength, so longer wavelengths make insignificant contributions to scenes illuminated by common light sources. However, particularly intense near-IR light (e.g., from IR lasers, IR LED sources, or from bright daylight with the visible light removed by colored gels) can be detected up to approximately 780 nm, and will be perceived as red light. Sources providing wavelengths as long as 1050 nm can be seen as a dull red glow in intense sources, causing some difficulty in near-IR illumination of scenes in the dark (usually this practical problem is solved by indirect illumination). Leaves are particularly bright in the near IR, and if all visible light leaks from around an IR-filter are blocked, and the eye is given a moment to adjust to the extremely dim image coming through a visually opaque IR-passing photographic filter, it is possible to see the Wood effect that consists of IR-glowing foliage.
What is the answer to this question: At what wavelength does the human eye become significantly less sensitive to light?

So...
700 nm
