Problem: Alloy:

When the alloy cools and solidifies (crystallizes), its mechanical properties will often be quite different from those of its individual constituents. A metal that is normally very soft and malleable, such as aluminium, can be altered by alloying it with another soft metal, like copper. Although both metals are very soft and ductile, the resulting aluminium alloy will be much harder and stronger. Adding a small amount of non-metallic carbon to iron produces an alloy called steel. Due to its very-high strength and toughness (which is much higher than pure iron), and its ability to be greatly altered by heat treatment, steel is one of the most common alloys in modern use. By adding chromium to steel, its resistance to corrosion can be enhanced, creating stainless steel, while adding silicon will alter its electrical characteristics, producing silicon steel.

What is another word for when alloys solidify?

A: crystallizes


Problem: The Republic of the Congo's sparse population is concentrated in the southwestern portion of the country, leaving the vast areas of tropical jungle in the north virtually uninhabited. Thus, Congo is one of the most urbanized countries in Africa, with 70% of its total population living in a few urban areas, namely in Brazzaville, Pointe-Noire or one of the small cities or villages lining the 534-kilometre (332 mi) railway which connects the two cities. In rural areas, industrial and commercial activity has declined rapidly in recent years, leaving rural economies dependent on the government for support and subsistence.
What percent of the population of the Congo lives outside urban areas?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
According to one of her biographers, Giles St Aubyn, Victoria wrote an average of 2,500 words a day during her adult life. From July 1832 until just before her death, she kept a detailed journal, which eventually encompassed 122 volumes. After Victoria's death, her youngest daughter, Princess Beatrice, was appointed her literary executor. Beatrice transcribed and edited the diaries covering Victoria's accession onwards, and burned the originals in the process. Despite this destruction, much of the diaries still exist. In addition to Beatrice's edited copy, Lord Esher transcribed the volumes from 1832 to 1861 before Beatrice destroyed them. Part of Victoria's extensive correspondence has been published in volumes edited by A. C. Benson, Hector Bolitho, George Earle Buckle, Lord Esher, Roger Fulford, and Richard Hough among others.
What year did Victoria stop keeping a journal?
A: unanswerable


Context and question: In China, a call to boycott French hypermart Carrefour from May 1 began spreading through mobile text messaging and online chat rooms amongst the Chinese over the weekend from April 12, accusing the company's major shareholder, the LVMH Group, of donating funds to the Dalai Lama. There were also calls to extend the boycott to include French luxury goods and cosmetic products. Chinese protesters organized boycotts of the French-owned retail chain Carrefour in major Chinese cities including Kunming, Hefei and Wuhan, accusing the French nation of pro-secessionist conspiracy and anti-Chinese racism. Some burned French flags, some added Swastika (due to its conotaions with Nazism) to the French flag, and spread short online messages calling for large protests in front of French consulates and embassy. Some shoppers who insisted on entering one of the Carrefour stores in Kunming were blocked by boycotters wielding large Chinese flags and hit by water bottles. Hundreds of people joined Anti-French rallies in Beijing, Wuhan, Hefei, Kunming and Qingdao, which quickly spread to other cities like Xi'an, Harbin and Jinan. Carrefour denied any support or involvement in the Tibetan issue, and had its staff in its Chinese stores wear uniforms emblazoned with the Chinese national flag and caps with Olympic insignia and as well as the words "Beijing 2008" to show its support for the games. The effort had to be ceased when the BOCOG deemed the use of official Olympic insignia as illegal and a violation of copyright.
What was burned during these boycotts?
Answer: the French flag


Question: In physics, the standard definition of a glass (or vitreous solid) is a solid formed by rapid melt quenching. The term glass is often used to describe any amorphous solid that exhibits a glass transition temperature Tg. If the cooling is sufficiently rapid (relative to the characteristic crystallization time) then crystallization is prevented and instead the disordered atomic configuration of the supercooled liquid is frozen into the solid state at Tg. The tendency for a material to form a glass while quenched is called glass-forming ability. This ability can be predicted by the rigidity theory. Generally, the structure of a glass exists in a metastable state with respect to its crystalline form, although in certain circumstances, for example in atactic polymers, there is no crystalline analogue of the amorphous phase.
Is there an answer to this question: What predicts glass-forming ability?

Answer: rigidity theory


Poultry (/ˌpoʊltriː/) are domesticated birds kept by humans for the eggs they produce, their meat, their feathers, or sometimes as pets. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes (which includes chickens, quails and turkeys) and the family Anatidae, in order Anseriformes, commonly known as "waterfowl" and including domestic ducks and domestic geese. Poultry also includes other birds that are killed for their meat, such as the young of pigeons (known as squabs) but does not include similar wild birds hunted for sport or food and known as game. The word "poultry" comes from the French/Norman word poule, itself derived from the Latin word pullus, which means small animal.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What language was the word "poultry" banned from?
Ah, so..
unanswerable
