Input: Read this: When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism. The relative size of each element in the mix plays a primary role in determining which mechanism will occur. When the atoms are relatively similar in size, the atom exchange method usually happens, where some of the atoms composing the metallic crystals are substituted with atoms of the other constituent. This is called a substitutional alloy. Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms. With the interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully replace an atom in the crystals of the base metal. The smaller atoms become trapped in the spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix. Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms.
Question: What is formed when molten metal is separated from other substances?

Output: unanswerable


QUES: In 2005, in order to host The 10th National Game of People's Republic of China, there was a new stadium, Nanjing Olympic Sports Center, constructed in Nanjing. Compared to Wutaishan Sports Center, which the major stadium's capacity is 18,500, Nanjing Olympic Sports Center has a more advanced stadium which is big enough to seat 60,000 spectators. Its gymnasium has capacity of 13,000, and natatorium of capacity 3,000.

When was the Nanjing Olympic Sports Center built?
What is the answer?
ANS: 2005


QUES: French cuisine, West Indian cuisine, Creole cuisine, Italian cuisine and Asian cuisine are common in St. Barthélemy. The island has over 70 restaurants serving many dishes and others are a significant number of gourmet restaurants; many of the finest restaurants are located in the hotels. There are also a number of snack restaurants which the French call "les snacks" or "les petits creux" which include sandwiches, pizzas and salads. West Indian cuisine, steamed vegetables with fresh fish is common; Creole dishes tend to be spicier. The island hosts gastronomic events throughout the year, with dishes such as spring roll of shrimp and bacon, fresh grilled lobster, Chinese noodle salad with coconut milk, and grilled beef fillet etc.
Where are most of the nice restaurants located?

ANS: in the hotels


These processes are also important in biological responses to pollution; for example, sulfate-reducing bacteria are largely responsible for the production of the highly toxic forms of mercury (methyl- and dimethylmercury) in the environment. Non-respiratory anaerobes use fermentation to generate energy and reducing power, secreting metabolic by-products (such as ethanol in brewing) as waste. Facultative anaerobes can switch between fermentation and different terminal electron acceptors depending on the environmental conditions in which they find themselves.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How can anaerobes adjust to the surrounding environment?
Ah, so.. can switch between fermentation and different terminal electron acceptors


Question: In 1949, the club unveiled a modernised crest featuring the same style of cannon below the club's name, set in blackletter, and above the coat of arms of the Metropolitan Borough of Islington and a scroll inscribed with the club's newly adopted Latin motto, Victoria Concordia Crescit "victory comes from harmony", coined by the club's programme editor Harry Homer. For the first time, the crest was rendered in colour, which varied slightly over the crest's lifespan, finally becoming red, gold and green. Because of the numerous revisions of the crest, Arsenal were unable to copyright it. Although the club had managed to register the crest as a trademark, and had fought (and eventually won) a long legal battle with a local street trader who sold "unofficial" Arsenal merchandise, Arsenal eventually sought a more comprehensive legal protection. Therefore, in 2002 they introduced a new crest featuring more modern curved lines and a simplified style, which was copyrightable. The cannon once again faces east and the club's name is written in a sans-serif typeface above the cannon. Green was replaced by dark blue. The new crest was criticised by some supporters; the Arsenal Independent Supporters' Association claimed that the club had ignored much of Arsenal's history and tradition with such a radical modern design, and that fans had not been properly consulted on the issue.
Try to answer this question if possible: In what year did Arsenal produce a remodeled crest that could be copyrighted?
Answer: 2002


Context and question: Anxious to expand the company's broadcast and cable presence, longtime MCA head Lew Wasserman sought a rich partner.

What was the nationality of Matsushita Electric?
Answer:
