Context and question: Book 1 (at the head of the Odyssean section) opens with a storm which Juno, Aeneas' enemy throughout the poem, stirs up against the fleet. The storm drives the hero to the coast of Carthage, which historically was Rome's deadliest foe. The queen, Dido, welcomes the ancestor of the Romans, and under the influence of the gods falls deeply in love with him. At a banquet in Book 2, Aeneas tells the story of the sack of Troy, the death of his wife, and his escape, to the enthralled Carthaginians, while in Book 3 he recounts to them his wanderings over the Mediterranean in search of a suitable new home. Jupiter in Book 4 recalls the lingering Aeneas to his duty to found a new city, and he slips away from Carthage, leaving Dido to commit suicide, cursing Aeneas and calling down revenge in a symbolic anticipation of the fierce wars between Carthage and Rome. In Book 5, Aeneas' father Anchises dies and funeral games are celebrated for him. On reaching Cumae, in Italy in Book 6, Aeneas consults the Cumaean Sibyl, who conducts him through the Underworld where Aeneas meets the dead Anchises who reveals Rome's destiny to his son.

Context and question: Anthropology is the study of humans and their societies in the past and present. Its main subdivisions are social anthropology and cultural anthropology, which describes the workings of societies around the world, linguistic anthropology, which investigates the influence of language in social life, and biological or physical anthropology, which concerns long-term development of the human organism. Archaeology, which studies past human cultures through investigation of physical evidence, is thought of as a branch of anthropology in the United States, while in Europe, it is viewed as a discipline in its own right, or grouped under other related disciplines such as history.
What is the study of human history?
Answer: unanswerable
Context and question: PCBs intended for extreme environments often have a conformal coating, which is applied by dipping or spraying after the components have been soldered. The coat prevents corrosion and leakage currents or shorting due to condensation. The earliest conformal coats were wax; modern conformal coats are usually dips of dilute solutions of silicone rubber, polyurethane, acrylic, or epoxy. Another technique for applying a conformal coating is for plastic to be sputtered onto the PCB in a vacuum chamber. The chief disadvantage of conformal coatings is that servicing of the board is rendered extremely difficult.
If a PCB is intended for use in an setting with extreme conditions, what would probably be applied?
Answer:
conformal coating
