Article: A red dye called Kermes was made beginning in the Neolithic Period by drying and then crushing the bodies of the females of a tiny scale insect in the genus Kermes, primarily Kermes vermilio. The insects live on the sap of certain trees, especially Kermes oak trees near the Mediterranean region. Jars of kermes have been found in a Neolithic cave-burial at Adaoutse, Bouches-du-Rhône. Kermes from oak trees was later used by Romans, who imported it from Spain. A different variety of dye was made from Porphyrophora hamelii (Armenian cochineal) scale insects that lived on the roots and stems of certain herbs. It was mentioned in texts as early as the 8th century BC, and it was used by the ancient Assyrians and Persians.

Question: What kind of bural was at Adaoutse, Bouches-du-Rhône?
Ans: Neolithic cave-burial


Article: AA gunnery was a difficult business. The problem was of successfully aiming a shell to burst close to its target's future position, with various factors affecting the shells' predicted trajectory. This was called deflection gun-laying, 'off-set' angles for range and elevation were set on the gunsight and updated as their target moved. In this method when the sights were on the target, the barrel was pointed at the target's future position. Range and height of the target determined fuse length. The difficulties increased as aircraft performance improved.

Question: What was the problem with AA gunnery?
Ans: successfully aiming a shell to burst close to its target's future position


Article: The assumption of the use of a two-beamed cross does not determine the number of nails used in the crucifixion and some theories suggest three nails while others suggest four nails. However, throughout history larger numbers of nails have been hypothesized, at times as high as 14 nails. These variations are also present in the artistic depictions of the crucifixion. In the Western Church, before the Renaissance usually four nails would be depicted, with the feet side by side. After the Renaissance most depictions use three nails, with one foot placed on the other. Nails are almost always depicted in art, although Romans sometimes just tied the victims to the cross. The tradition also carries to Christian emblems, e.g. the Jesuits use three nails under the IHS monogram and a cross to symbolize the crucifixion.

Question: What do all artworks have in common regarding the crucifixion?
Ans: Nails are almost always depicted


Article: Russian is notable for its distinction based on palatalization of most of the consonants. While /k/, /ɡ/, /x/ do have palatalized allophones [kʲ, ɡʲ, xʲ], only /kʲ/ might be considered a phoneme, though it is marginal and generally not considered distinctive (the only native minimal pair which argues for /kʲ/ to be a separate phoneme is "это ткёт" ([ˈɛtə tkʲɵt], 'it weaves')/"этот кот" ([ˈɛtət kot], 'this cat')). Palatalization means that the center of the tongue is raised during and after the articulation of the consonant. In the case of /tʲ/ and /dʲ/, the tongue is raised enough to produce slight frication (affricate sounds). These sounds: /t, d, ts, s, z, n and rʲ/ are dental, that is pronounced with the tip of the tongue against the teeth rather than against the alveolar ridge.

Question: How are 'dental' sounds pronounced?
Ans:
with the tip of the tongue against the teeth rather than against the alveolar ridge
