Problem: Queen Victoria:

After the Indian Rebellion of 1857, the British East India Company, which had ruled much of India, was dissolved, and Britain's possessions and protectorates on the Indian subcontinent were formally incorporated into the British Empire. The Queen had a relatively balanced view of the conflict, and condemned atrocities on both sides. She wrote of "her feelings of horror and regret at the result of this bloody civil war", and insisted, urged on by Albert, that an official proclamation announcing the transfer of power from the company to the state "should breathe feelings of generosity, benevolence and religious toleration". At her behest, a reference threatening the "undermining of native religions and customs" was replaced by a passage guaranteeing religious freedom.

What company ruled much of India before the end of the Indian Rebellion?
---
A: British East India Company


Problem: The key advantage of the four-rail system is that neither running rail carries any current. This scheme was introduced because of the problems of return currents, intended to be carried by the earthed (grounded) running rail, flowing through the iron tunnel linings instead. This can cause electrolytic damage and even arcing if the tunnel segments are not electrically bonded together. The problem was exacerbated because the return current also had a tendency to flow through nearby iron pipes forming the water and gas mains. Some of these, particularly Victorian mains that predated London's underground railways, were not constructed to carry currents and had no adequate electrical bonding between pipe segments. The four-rail system solves the problem. Although the supply has an artificially created earth point, this connection is derived by using resistors which ensures that stray earth currents are kept to manageable levels. Power-only rails can be mounted on strongly insulating ceramic chairs to minimise current leak, but this is not possible for running rails which have to be seated on stronger metal chairs to carry the weight of trains. However, elastomeric rubber pads placed between the rails and chairs can now solve part of the problem by insulating the running rails from the current return should there be a leakage through the running rails.
What insures minimal current leak during power rails instalation?

Answer: ceramic chairs


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Semi-additive is the most common process: The unpatterned board has a thin layer of copper already on it. A reverse mask is then applied. (Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces.) Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight. Tin-lead or other surface platings are then applied. The mask is stripped away and a brief etching step removes the now-exposed bare original copper laminate from the board, isolating the individual traces. Some single-sided boards which have plated-through holes are made in this way. General Electric made consumer radio sets in the late 1960s using additive boards.
What company used to make radios with additive boards in the mid-20th century?
A: General Electric


Context and question: Pressing the sheet removes the water by force; once the water is forced from the sheet, a special kind of felt, which is not to be confused with the traditional one, is used to collect the water; whereas when making paper by hand, a blotter sheet is used instead.
How is the water removed by force from a sheet of wood?
Answer: unanswerable


Question: The increased consumption of reading materials of all sorts was one of the key features of the "social" Enlightenment. Developments in the Industrial Revolution allowed consumer goods to be produced in greater quantities at lower prices, encouraging the spread of books, pamphlets, newspapers and journals – "media of the transmission of ideas and attitudes". Commercial development likewise increased the demand for information, along with rising populations and increased urbanisation. However, demand for reading material extended outside of the realm of the commercial, and outside the realm of the upper and middle classes, as evidenced by the Bibliothèque Bleue. Literacy rates are difficult to gauge, but in France at least, the rates doubled over the course of the 18th century. Reflecting the decreasing influence of religion, the number of books about science and art published in Paris doubled from 1720 to 1780, while the number of books about religion dropped to just one-tenth of the total.
Is there an answer to this question: The increased consumption of what type of material was one of the key features of the "social" Enlightenment?

Answer: reading materials


Problem: Immaculate Conception:

The popularity of this particular representation of The Immaculate Conception spread across the rest of Europe, and has since remained the best known artistic depiction of the concept: in a heavenly realm, moments after her creation, the spirit of Mary (in the form of a young woman) looks up in awe at (or bows her head to) God. The moon is under her feet and a halo of twelve stars surround her head, possibly a reference to "a woman clothed with the sun" from Revelation 12:1-2. Additional imagery may include clouds, a golden light, and cherubs. In some paintings the cherubim are holding lilies and roses, flowers often associated with Mary.

What is under the feet of the Cherubs?
