Problem: In August 2013, a launching ceremony for Japan's largest military ship since World War II was held in Yokohama. The 820-foot-long (250 m), 19,500-ton flattop Izumo was deployed in March 2015. The ship is able to carry up to 14 helicopters; however, only seven ASW helicopters and two SAR helicopters were planned for the initial aircraft complement. For other operations, 400 troops and fifty 3.5 t trucks (or equivalent equipment) can also be carried. The flight deck has five helicopter landing spots that allow simultaneous landings or take-offs. The ship is equipped with two Phalanx CIWS and two SeaRAM for its defense. The destroyers of this class were initially intended to replace the two ships of the Shirane class, which were originally scheduled to begin decommissioning in FY2014.
What was the August 2013 launching ceremony in Yokohama held for?
The answer is the following: Japan's largest military ship since World War II

Problem: Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as from the power grid, inverters or generators. Small motors may be found in electric watches. General-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors may be classified by electric power source type, internal construction, application, type of motion output, and so on.
What is the main example of a DC power source?
The answer is the following: batteries

Problem: Livy presents these as signs of widespread failure in Roman religio. The major prodigies included the spontaneous combustion of weapons, the apparent shrinking of the sun's disc, two moons in a daylit sky, a cosmic battle between sun and moon, a rain of red-hot stones, a bloody sweat on statues, and blood in fountains and on ears of corn: all were expiated by sacrifice of "greater victims". The minor prodigies were less warlike but equally unnatural; sheep become goats, a hen become a cock (and vice versa) – these were expiated with "lesser victims". The discovery of an androgynous four-year-old child was expiated by its drowning and the holy procession of 27 virgins to the temple of Juno Regina, singing a hymn to avert disaster: a lightning strike during the hymn rehearsals required further expiation. Religious restitution is proved only by Rome's victory.
What is the only proof of religious success over prodigies?
The answer is the following: Rome's victory

Problem: In 1839, Melbourne resigned after Radicals and Tories (both of whom Victoria detested) voted against a bill to suspend the constitution of Jamaica. The bill removed political power from plantation owners who were resisting measures associated with the abolition of slavery. The Queen commissioned a Tory, Sir Robert Peel, to form a new ministry. At the time, it was customary for the prime minister to appoint members of the Royal Household, who were usually his political allies and their spouses. Many of the Queen's ladies of the bedchamber were wives of Whigs, and Peel expected to replace them with wives of Tories. In what became known as the bedchamber crisis, Victoria, advised by Melbourne, objected to their removal. Peel refused to govern under the restrictions imposed by the Queen, and consequently resigned his commission, allowing Melbourne to return to office.
Who did Robert Peel want to replace the ladies of the bedchamber with, instead of wives of Whigs?
The answer is the following:
wives of Tories
