Problem: Given the question: Question: "Which caves showed devices that were used to produces fires?" Context: "With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 BCE, fire was kindled in the caves of Peking Man. Prehistoric people used primitive oil lamps to illuminate surroundings. These lamps were made from naturally occurring materials such as rocks, shells, horns and stones, were filled with grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. Hundreds of these lamps (hollow worked stones) have been found in the Lascaux caves in modern-day France, dating to about 15,000 years ago. Oily animals (birds and fish) were also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps were also invented. Chandeliers were an early form of "light fixture"." Answer:

Question: Question: "Who was Dionysus compared with?" Context: "While the new plebeian nobility made social, political and religious inroads on traditionally patrician preserves, their electorate maintained their distinctive political traditions and religious cults. During the Punic crisis, popular cult to Dionysus emerged from southern Italy; Dionysus was equated with Father Liber, the inventor of plebeian augury and personification of plebeian freedoms, and with Roman Bacchus. Official consternation at these enthusiastic, unofficial Bacchanalia cults was expressed as moral outrage at their supposed subversion, and was followed by ferocious suppression. Much later, a statue of Marsyas, the silen of Dionysus flayed by Apollo, became a focus of brief symbolic resistance to Augustus' censorship. Augustus himself claimed the patronage of Venus and Apollo; but his settlement appealed to all classes. Where loyalty was implicit, no divine hierarchy need be politically enforced; Liber's festival continued." Answer:
Answer: Father Liber, the inventor of plebeian augury and personification of plebeian freedoms, and with Roman Bacchus
