Problem: Guam:

In 1899, the local postage stamps were overprinted "Guam" as was done for the other former Spanish colonies, but this was discontinued shortly thereafter and regular U.S. postage stamps have been used ever since. Because Guam is also part of the U.S. Postal System (postal abbreviation: GU, ZIP code range: 96910–96932), mail to Guam from the U.S. mainland is considered domestic and no additional charges are required. Private shipping companies, such as FedEx, UPS, and DHL, however, have no obligation to do so, and do not regard Guam as domestic.

Which private shipping company charges more to ship packages to Guam?

A: unanswerable


Problem: In January 1950, the Church of Cyprus organised a referendum under the supervision of clerics and with no Turkish Cypriot participation, where 96% of the participating Greek Cypriots voted in favour of enosis, The Greeks were 80.2% of the total island' s population at the time (census 1946). Restricted autonomy under a constitution was proposed by the British administration but eventually rejected. In 1955 the EOKA organisation was founded, seeking union with Greece through armed struggle. At the same time the Turkish Resistance Organisation (TMT), calling for Taksim, or partition, was established by the Turkish Cypriots as a counterweight. The British had also adopted at the time a policy of "divide and rule". Woodhouse, a British official in Cyprus, revealed that then British Foreign Secretary Harold Macmillan "urged the Britons in Cyprus to stir up the Turks in order to neutralise Greek agitation". British officials also tolerated the creation of the Turkish underground organisation T.M.T. The Secretary of State for the Colonies in a letter dated 15 July 1958 had advised the Governor of Cyprus not to act against T.M.T despite its illegal actions so as not to harm British relations with the Turkish government.
In 1946, the Greeks made up what percent of Cyprus' population?

Answer: 80.2%


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Digimon was first conceived as a virtual pet toy in the vein of Tamagotchis and, as such, took influence from Tamagotchis' cute and round designs. The small areas of the screens (16 by 16 pixels) meant that character designers had to create monsters whose forms would be easily recognizable. As such, many of the early Digimon—including Tyrannomon, the first one ever created—were based on dinosaurs. Many further designs were created by Kenji Watanabe, who was brought in to help with the "X-Antibody" creatures and art for the Digimon collectible card game. Watanabe was one influenced by American comics, which were beginning to gain popularity in Japan, and as such began to make his characters look stronger and "cool." The character creation process, however, has for most of the franchise's history been collaborative and reliant on conversation and brainstorming.
What was originally based on an actual pet?
A: unanswerable


Context and question: Additionally, the Italian Eritrea administration opened a number of new factories, which produced buttons, cooking oil, pasta, construction materials, packing meat, tobacco, hide and other household commodities. In 1939, there were around 2,198 factories and most of the employees were Eritrean citizens. The establishment of industries also made an increase in the number of both Italians and Eritreans residing in the cities. The number of Italians residing in the territory increased from 4,600 to 75,000 in five years; and with the involvement of Eritreans in the industries, trade and fruit plantation was expanded across the nation, while some of the plantations were owned by Eritreans.
What was the main export of Italian Eritrea in 1939?
Answer: unanswerable


Question: Thomas Edison began serious research into developing a practical incandescent lamp in 1878. Edison filed his first patent application for "Improvement In Electric Lights" on 14 October 1878. After many experiments, first with carbon in the early 1880s and then with platinum and other metals, in the end Edison returned to a carbon filament. The first successful test was on 22 October 1879, and lasted 13.5 hours. Edison continued to improve this design and by 4 November 1879, filed for a US patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires." Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," Edison and his team later discovered that a carbonized bamboo filament could last more than 1200 hours. In 1880, the Oregon Railroad and Navigation Company steamer, Columbia, became the first application for Edison's incandescent electric lamps (it was also the first ship to execute use of a dynamo).
Is there an answer to this question: What did Edison turn refuse to use after his experiment with platinum and other metals?

Answer: unanswerable

Control of labour and inter-group conflict is characteristic of corporate-level or 'tribal' groups, headed by a charismatic individual; whether a 'big man' or a proto-chief, functioning as a lineage-group head. Whether a non-hierarchical system of organization existed is debatable, and there is no evidence that explicitly suggests that Neolithic societies functioned under any dominating class or individual, as was the case in the chiefdoms of the European Early Bronze Age. Theories to explain the apparent implied egalitarianism of Neolithic (and Paleolithic) societies have arisen, notably the Marxist concept of primitive communism.
What theory describes the implied egalitarianism of Neolithic societies?
A:
Marxist concept of primitive communism
