Problem: Jehovah%27s Witnesses:

From 1879, Watch Tower supporters gathered as autonomous congregations to study the Bible topically. Thirty congregations were founded, and during 1879 and 1880, Russell visited each to provide the format he recommended for conducting meetings. As congregations continued to form during Russell's ministry, they each remained self-administrative, functioning under the congregationalist style of church governance. In 1881, Zion's Watch Tower Tract Society was presided over by William Henry Conley, and in 1884, Charles Taze Russell incorporated the society as a non-profit business to distribute tracts and Bibles. By about 1900, Russell had organized thousands of part- and full-time colporteurs, and was appointing foreign missionaries and establishing branch offices. By the 1910s, Russell's organization maintained nearly a hundred "pilgrims," or traveling preachers. Russell engaged in significant global publishing efforts during his ministry, and by 1912, he was the most distributed Christian author in the United States.

Problem: Burke was a leading sceptic with respect to democracy. While admitting that theoretically, in some cases it might be desirable, he insisted a democratic government in Britain in his day would not only be inept, but also oppressive. He opposed democracy for three basic reasons. First, government required a degree of intelligence and breadth of knowledge of the sort that occurred rarely among the common people. Second, he thought that if they had the vote, common people had dangerous and angry passions that could be aroused easily by demagogues; he feared that the authoritarian impulses that could be empowered by these passions would undermine cherished traditions and established religion, leading to violence and confiscation of property. Third, Burke warned that democracy would create a tyranny over unpopular minorities, who needed the protection of the upper classes.
What type of government system did Burke favor?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
More than 12,000 miles (19,000 km) of roads make up the state's major highway skeleton, including state-operated highways, ten turnpikes or major toll roads, and the longest drivable stretch of Route 66 in the nation. In 2008, Interstate 44 in Oklahoma City was Oklahoma's busiest highway, with a daily traffic volume of 123,300 cars. In 2010, the state had the nation's third highest number of bridges classified as structurally deficient, with nearly 5,212 bridges in disrepair, including 235 National Highway System Bridges.
How many miles of highways are in Oklahoma?
A: More than 12,000

Context and question: Neptune also resembles Uranus in its magnetosphere, with a magnetic field strongly tilted relative to its rotational axis at 47 and offset at least 0.55 radii, or about 13500 km from the planet's physical centre. Before Voyager 2's arrival at Neptune, it was hypothesised that Uranus's tilted magnetosphere was the result of its sideways rotation. In comparing the magnetic fields of the two planets, scientists now think the extreme orientation may be characteristic of flows in the planets' interiors. This field may be generated by convective fluid motions in a thin spherical shell of electrically conducting liquids (probably a combination of ammonia, methane and water) resulting in a dynamo action.
What planet besides Neptune has a sideways rotation?
Answer: Uranus's

Question: Elevators with more than 30 m (98 ft) of travel have a system called compensation. This is a separate set of cables or a chain attached to the bottom of the counterweight and the bottom of the elevator cab. This makes it easier to control the elevator, as it compensates for the differing weight of cable between the hoist and the cab. If the elevator cab is at the top of the hoist-way, there is a short length of hoist cable above the car and a long length of compensating cable below the car and vice versa for the counterweight. If the compensation system uses cables, there will be an additional sheave in the pit below the elevator, to guide the cables. If the compensation system uses chains, the chain is guided by a bar mounted between the counterweight railway lines.
Is there an answer to this question: What is the chain guided by in a compensation system that uses chains?

Answer: a bar mounted between the counterweight railway lines

Brain tissue consumes a large amount of energy in proportion to its volume, so large brains place severe metabolic demands on animals. The need to limit body weight in order, for example, to fly, has apparently led to selection for a reduction of brain size in some species, such as bats. Most of the brain's energy consumption goes into sustaining the electric charge (membrane potential) of neurons. Most vertebrate species devote between 2% and 8% of basal metabolism to the brain. In primates, however, the percentage is much higherin humans it rises to 2025%. The energy consumption of the brain does not vary greatly over time, but active regions of the cerebral cortex consume somewhat more energy than inactive regions; this forms the basis for the functional brain imaging methods PET, fMRI, and NIRS. The brain typically gets most of its energy from oxygen-dependent metabolism of glucose (i.e., blood sugar), but ketones provide a major alternative source, together with contributions from medium chain fatty acids (caprylic and heptanoic acids), lactate, acetate, and possibly amino acids.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where does the brain usually get most of its energy from inside the body?
Ah, so..
glucose (i.e., blood sugar
