Here is a question about this article: New chemical glass compositions or new treatment techniques can be initially investigated in small-scale laboratory experiments. The raw materials for laboratory-scale glass melts are often different from those used in mass production because the cost factor has a low priority. In the laboratory mostly pure chemicals are used. Care must be taken that the raw materials have not reacted with moisture or other chemicals in the environment (such as alkali or alkaline earth metal oxides and hydroxides, or boron oxide), or that the impurities are quantified (loss on ignition). Evaporation losses during glass melting should be considered during the selection of the raw materials, e.g., sodium selenite may be preferred over easily evaporating SeO2. Also, more readily reacting raw materials may be preferred over relatively inert ones, such as Al(OH)3 over Al2O3. Usually, the melts are carried out in platinum crucibles to reduce contamination from the crucible material. Glass homogeneity is achieved by homogenizing the raw materials mixture (glass batch), by stirring the melt, and by crushing and re-melting the first melt. The obtained glass is usually annealed to prevent breakage during processing.
What is the answer to this question: What is the reason for crushing the glass and melting it again?
****
So... homogeneity

Many districts and landmarks in New York City have become well known, and the city received a record 56 million tourists in 2014, hosting three of the world's ten most visited tourist attractions in 2013. Several sources have ranked New York the most photographed city in the world. Times Square, iconic as the world's "heart" and its "Crossroads", is the brightly illuminated hub of the Broadway Theater District, one of the world's busiest pedestrian intersections, and a major center of the world's entertainment industry. The names of many of the city's bridges, skyscrapers, and parks are known around the world. Anchored by Wall Street in the Financial District of Lower Manhattan, New York City has been called both the most economically powerful city and the leading financial center of the world, and the city is home to the world's two largest stock exchanges by total market capitalization, the New York Stock Exchange and NASDAQ. Manhattan's real estate market is among the most expensive in the world. Manhattan's Chinatown incorporates the highest concentration of Chinese people in the Western Hemisphere, with multiple signature Chinatowns developing across the city. Providing continuous 24/7 service, the New York City Subway is one of the most extensive metro systems worldwide, with 469 stations in operation. New York City's higher education network comprises over 120 colleges and universities, including Columbia University, New York University, and Rockefeller University, which have been ranked among the top 35 in the world.
In what borough is Wall Street located?
****
The answer: Manhattan

Problem: Please answer a question about the following article about Modern history:
The Great Depression ended at different times in different countries with the effect lasting into the next era. America's Great Depression ended in 1941 with America's entry into World War II. The majority of countries set up relief programs, and most underwent some sort of political upheaval, pushing them to the left or right. In some world states, the desperate citizens turned toward nationalist demagoguesthe most infamous being Adolf Hitlersetting the stage for the next era of war. The convulsion brought on by the worldwide depression resulted in the rise of Nazism. In Asia, Japan became an ever more assertive power, especially with regards to China.
In some world states who did the people turn to?
A: nationalist demagogues

Seattle's political culture is very liberal and progressive for the United States, with over 80% of the population voting for the Democratic Party. All precincts in Seattle voted for Democratic Party candidate Barack Obama in the 2012 presidential election. In partisan elections for the Washington State Legislature and United States Congress, nearly all elections are won by Democrats. Seattle is considered the first major American city to elect a female mayor, Bertha Knight Landes. It has also elected an openly gay mayor, Ed Murray, and a socialist councillor, Kshama Sawant. For the first time in United States history, an openly gay black woman was elected to public office when Sherry Harris was elected as a Seattle city councillor in 1991. The majority of the current city council is female, while white men comprise a minority.

What party members win most state and national legislative elections?
Answer: Democrats

Problem: Tourism is considered another important industry in Nepal. This industry started around 1950, as the country's political makeup changed and ended the country's isolation from the rest of the world. In 1956, air transportation was established and the Tribhuvan Highway, between Kathmandu and Raxaul (at India's border), was started. Separate organizations were created in Kathmandu to promote this activity; some of these include the Tourism Development Board, the Department of Tourism and the Civil Aviation Department. Furthermore, Nepal became a member of several international tourist associations. Establishing diplomatic relations with other nations further accentuated this activity. The hotel industry, travel agencies, training of tourist guides, and targeted publicity campaigns are the chief reasons for the remarkable growth of this industry in Nepal, and in Kathmandu in particular.
Approximately when did the Nepalese tourism industry begin?
The answer is the following: 1950

Input: Article: In the first 200 years that black people were in the United States, they primarily identified themselves by their specific ethnic group (closely allied to language) and not by skin color. Individuals identified themselves, for example, as Ashanti, Igbo, Bakongo, or Wolof. However, when the first captives were brought to the Americas, they were often combined with other groups from West Africa, and individual ethnic affiliations were not generally acknowledged by English colonists. In areas of the Upper South, different ethnic groups were brought together. This is significant as the captives came from a vast geographic region: the West African coastline stretching from Senegal to Angola and in some cases from the south-east coast such as Mozambique. A new African-American identity and culture was born that incorporated elements of the various ethnic groups and of European cultural heritage, resulting in fusions such as the Black church and Black English. This new identity was based on provenance and slave status rather than membership in any one ethnic group.[citation needed] By contrast, slave records from Louisiana show that the French and Spanish colonists recorded more complete identities of the West Africans, including ethnicities and given tribal names.

Now answer this question: Which colonists recorded more complete identities of the West Africans?

Output:
French and Spanish colonists
