Input: Read this: The country is a significant agricultural producer within the EU. Greece has the largest economy in the Balkans and is as an important regional investor. Greece was the largest foreign investor in Albania in 2013, the third in Bulgaria, in the top-three in Romania and Serbia and the most important trading partner and largest foreign investor in the former Yugoslav Republic of Macedonia. The Greek telecommunications company OTE has become a strong investor in former Yugoslavia and in other Balkan countries.
Question: What Greek telecommunications company has become a strong investor in former Yugoslavia?

Output: OTE

QUES: The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS2) and to a lesser extent chalcocite (Cu2S). These minerals are concentrated from crushed ores to the level of 1015% copper by froth flotation or bioleaching. Heating this material with silica in flash smelting removes much of the iron as slag. The process exploits the greater ease of converting iron sulfides into its oxides, which in turn react with the silica to form the silicate slag, which floats on top of the heated mass. The resulting copper matte consisting of Cu2S is then roasted to convert all sulfides into oxides:

What do the sulfides convert to after the copper matte is frozen?
What is the answer?
ANS: unanswerable

QUES: The cellular phone carrier group Open Mobile Terminal Platform (OMTP) in 2007 endorsed micro-USB as the standard connector for data and power on mobile devices In addition, on 22 October 2009 the International Telecommunication Union (ITU) has also announced that it had embraced micro-USB as the Universal Charging Solution its "energy-efficient one-charger-fits-all new mobile phone solution," and added: "Based on the Micro-USB interface, UCS chargers also include a 4-star or higher efficiency ratingup to three times more energy-efficient than an unrated charger."
When did the ITU announce that it had embraced micro-USB as the Universal Charging Solution?

ANS: 22 October 2009

Phase change materials such as paraffin wax and Glauber's salt are another thermal storage media. These materials are inexpensive, readily available, and can deliver domestically useful temperatures (approximately 64 C or 147 F). The "Dover House" (in Dover, Massachusetts) was the first to use a Glauber's salt heating system, in 1948. Solar energy can also be stored at high temperatures using molten salts. Salts are an effective storage medium because they are low-cost, have a high specific heat capacity and can deliver heat at temperatures compatible with conventional power systems. The Solar Two used this method of energy storage, allowing it to store 1.44 terajoules (400,000 kWh) in its 68 cubic metres storage tank with an annual storage efficiency of about 99%.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the name of the heating system that first used Glauber's salt?
Ah, so.. Dover House

Question: The preserved records of the Reichssicherheitshauptamt (the Reich Security Main Office) show the persecution of Freemasons during the Holocaust. RSHA Amt VII (Written Records) was overseen by Professor Franz Six and was responsible for "ideological" tasks, by which was meant the creation of antisemitic and anti-Masonic propaganda. While the number is not accurately known, it is estimated that between 80,000 and 200,000 Freemasons were killed under the Nazi regime. Masonic concentration camp inmates were graded as political prisoners and wore an inverted red triangle.
Try to answer this question if possible: How many Freemasons were killed under the Nazi regime?
Answer: between 80,000 and 200,000

Context and question: Wood, in the strict sense, is yielded by trees, which increase in diameter by the formation, between the existing wood and the inner bark, of new woody layers which envelop the entire stem, living branches, and roots. This process is known as secondary growth; it is the result of cell division in the vascular cambium, a lateral meristem, and subsequent expansion of the new cells. Where there are clear seasons, growth can occur in a discrete annual or seasonal pattern, leading to growth rings; these can usually be most clearly seen on the end of a log, but are also visible on the other surfaces. If these seasons are annual these growth rings are referred to as annual rings. Where there is no seasonal difference growth rings are likely to be indistinct or absent.
What is the process of trees growing out to get bigger around called?
Answer:
secondary growth
