Here is a question about this article: When there is a potential difference across the conductors (e.g., when a capacitor is attached across a battery), an electric field develops across the dielectric, causing positive charge +Q to collect on one plate and negative charge Q to collect on the other plate. If a battery has been attached to a capacitor for a sufficient amount of time, no current can flow through the capacitor. However, if a time-varying voltage is applied across the leads of the capacitor, a displacement current can flow.
What is the answer to this question: What is an example of when there exists a potential difference across the conductors?
****
So... when a capacitor is attached across a battery

The problem: Answer a question about this article:
Incandescent bulbs are much less efficient than most other types of electric lighting; incandescent bulbs convert less than 5% of the energy they use into visible light, with standard light bulbs averaging about 2.2%. The remaining energy is converted into heat. The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared with 60 lm/W for a compact fluorescent bulb or 150 lm/W for some white LED lamps. Some applications of the incandescent bulb deliberately use the heat generated by the filament. Such applications include incubators, brooding boxes for poultry, heat lights for reptile tanks, infrared heating for industrial heating and drying processes, lava lamps, and the Easy-Bake Oven toy. Incandescent bulbs typically have short lifetimes compared with other types of lighting; around 1,000 hours for home light bulbs versus typically 10,000 hours for compact fluorescents and 30,000 hours for lighting LEDs.
What percentage of energy does a standard light bulb actually convert to visible light?
****
The answer: 2.2%

Problem: Please answer a question about the following article about Samoa:
The Samoan islands have been produced by vulcanism, the source of which is the Samoa hotspot which is probably the result of a mantle plume. While all of the islands have volcanic origins, only Savai'i, the western most island in Samoa, is volcanically active with the most recent eruptions in Mt Matavanu (19051911), Mata o le Afi (1902) and Mauga Afi (1725). The highest point in Samoa is Mt Silisili, at 1858 m (6,096 ft). The Saleaula lava fields situated on the central north coast of Savai'i are the result of the Mt Matavanu eruptions which left 50 km (20 sq mi) of solidified lava.
What natural process formed the land masses that would become the Samoan islands?
A: vulcanism

William Pitt, who entered the cabinet in 1756, had a grand vision for the war that made it entirely different from previous wars with France. As prime minister Pitt committed Britain to a grand strategy of seizing the entire French Empire, especially its possessions in North America and India. Britain's main weapon was the Royal Navy, which could control the seas and bring as many invasion troops as were needed. He also planned to use colonial forces from the Thirteen American colonies, working under the command of British regulars, to invade new France. In order to tie the French army down he subsidized his European allies. Pitt Head of the government from 1756 to 1761, and even after that the British continued his strategy. It proved completely successful. Pitt had a clear appreciation of the enormous value of imperial possessions, and realized how vulnerable was the French Empire.

What locations did Pitt want from France?
Answer: North America and India

Problem: In 1986, the Compact of Free Association with the United States entered into force, granting the Republic of the Marshall Islands (RMI) its sovereignty. The Compact provided for aid and U.S. defense of the islands in exchange for continued U.S. military use of the missile testing range at Kwajalein Atoll. The independence procedure was formally completed under international law in 1990, when the UN officially ended the Trusteeship status pursuant to Security Council Resolution 683.
Where in the Marshall Islands does the United States have a missile testing range?
The answer is the following: Kwajalein Atoll

Input: Article: The simplest way to gain information about brain anatomy is by visual inspection, but many more sophisticated techniques have been developed. Brain tissue in its natural state is too soft to work with, but it can be hardened by immersion in alcohol or other fixatives, and then sliced apart for examination of the interior. Visually, the interior of the brain consists of areas of so-called grey matter, with a dark color, separated by areas of white matter, with a lighter color. Further information can be gained by staining slices of brain tissue with a variety of chemicals that bring out areas where specific types of molecules are present in high concentrations. It is also possible to examine the microstructure of brain tissue using a microscope, and to trace the pattern of connections from one brain area to another.

Now answer this question: Brain tissue is naturally soft, but can be stiffened with what liquid?

Output:
alcohol
