QUES: In addressing the question of who invented the incandescent lamp, historians Robert Friedel and Paul Israel list 22 inventors of incandescent lamps prior to Joseph Swan and Thomas Edison. They conclude that Edison's version was able to outstrip the others because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve (by use of the Sprengel pump) and a high resistance that made power distribution from a centralized source economically viable.

Which three historians wrote the conclusion that Edison's version was more viable than other early versions?
What is the answer?
ANS: unanswerable

QUES: In 2003, additional UN sanctions were placed on Liberian timber exports, which had risen from US$5 million in 1997 to over US$100 million in 2002 and were believed to be funding rebels in Sierra Leone. These sanctions were lifted in 2006. Due in large part to foreign aid and investment inflow following the end of the war, Liberia maintains a large account deficit, which peaked at nearly 60% in 2008. Liberia gained observer status with the World Trade Organization in 2010 and is in the process of acquiring full member status.
Why were sanctions place on Liberian timber exports?

ANS: were believed to be funding rebels in Sierra Leone.

For centuries, various peoples in modern-day Nigeria traded overland with traders from North Africa. Cities in the area became regional centres in a broad network of trade routes that spanned western, central and northern Africa. In the 16th century, Spanish and Portuguese explorers were the first Europeans to begin significant, direct trade with peoples of modern-day Nigeria, at the port they named Lagos and in Calabar. Europeans traded goods with peoples at the coast; coastal trade with Europeans also marked the beginnings of the Atlantic slave trade. The port of Calabar on the historical Bight of Biafra (now commonly referred to as the Bight of Bonny) become one of the largest slave trading posts in West Africa in the era of the transatlantic slave trade. Other major slaving ports in Nigeria were located in Badagry, Lagos on the Bight of Benin and on Bonny Island on the Bight of Biafra. The majority of those enslaved and taken to these ports were captured in raids and wars. Usually the captives were taken back to the conquerors' territory as forced labour; after time, they were sometimes acculturated and absorbed into the conquerors' society. A number of slave routes were established throughout Nigeria linking the hinterland areas with the major coastal ports. Some of the more prolific slave traders were linked with the Oyo Empire in the southwest, the Aro Confederacy in the southeast and the Sokoto Caliphate in the north.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which countries' explorers were the first Europeans to trade with Nigeria?
Ah, so.. Spanish and Portuguese

Question: As a consequence, there was a crisis in international confidence in Greece's ability to repay its sovereign debt, as reflected by the rise of the country's borrowing rates (although their slow rise the 10-year government bond yield only exceeded 7% in April 2010 coinciding with a large number of negative articles, has led to arguments about the role of international news media in the evolution of the crisis). In order to avert a default (as high borrowing rates effectively prohibited access to the markets), in May 2010 the other Eurozone countries, and the IMF, agreed to a "rescue package" which involved giving Greece an immediate 45 billion in bail-out loans, with more funds to follow, totaling 110 billion. In order to secure the funding, Greece was required to adopt harsh austerity measures to bring its deficit under control. Their implementation will be monitored and evaluated by the European Commission, the European Central Bank and the IMF.
Try to answer this question if possible: What organizations are keeping a watchful eye on how Greece is implementing austerity measures?
Answer: the European Commission, the European Central Bank and the IMF

Question: An alloy is a mixture of either pure or fairly pure chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal, such as wrought iron, in that, with an alloy, the added impurities are usually desirable and will typically have some useful benefit. Alloys are made by mixing two or more elements; at least one of which being a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy. The other constituents may or may not be metals but, when mixed with the molten base, they will be soluble, dissolving into the mixture.
Try to answer this question if possible: What is an alloy composed of?
Answer:
two or more elements
