Input: Read this: The Appalachian Mountains (i/ˌæpəˈleɪʃᵻn/ or /ˌæpəˈlætʃᵻn/,[note 1] French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period and once reached elevations similar to those of the Alps and the Rocky Mountains before they were eroded. The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west.
Question: During what period were the Appalachians named?

Output: unanswerable


QUES: The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies. Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer Institute for Solar Energy Systems ISE).

What is the name of the solar energy research facility in Japan?
What is the answer?
ANS: NEDO


QUES: Translation has served as a school of writing for many authors. Translators, including monks who spread Buddhist texts in East Asia, and the early modern European translators of the Bible, in the course of their work have shaped the very languages into which they have translated. They have acted as bridges for conveying knowledge between cultures; and along with ideas, they have imported from the source languages, into their own languages, loanwords and calques of grammatical structures, idioms and vocabulary.
What have translators acted as by conveying ignorance between cultures?

ANS: unanswerable


The officials in Mexico City reduced the price of corn from six cents to two cents a pound. The northern portion of the state continued to decline economically which led to another revolt led by G. Casavantes in August 1879; Governor Trías was accused of misappropriation of funds and inefficient administration of the state. Casavantes took the state capital and occupied it briefly; he was also successful in forcing Governor Trías to exile. Shortly afterwards, the federal government sent an entourage led by Treviño; Casavantes was immediately ordered to resign his position. Casavantes declared political victory as he was able to publicly accuse and depose Governor Trías. At the same time the states of Durango and Coahuila had a military confrontation over territorial claims and water rights; this altercation between the state required additional federal troops to stabilize the area. Later a dispute ensued again among the states of Coahuila, Durango, and Chihuahua over the mountain range area known as Sierra Mojada, when large deposits of gold ore was discovered. The state of Chihuahua officially submitted a declaration of protest in May 1880 that shortly after was amicably settled. Despite the difficulties at the beginning, Díaz was able to secure and stabilize the state, which earned the confidence and support of the people.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Durango and Coahuila had a military confrontation over what natural resource?
Ah, so.. water


Question: Since the end of the World Wars, the term "great power" has been joined by a number of other power classifications. Foremost among these is the concept of the superpower, used to describe those nations with overwhelming power and influence in the rest of the world. It was first coined in 1944 by William T.R. Fox and according to him, there were three superpowers: the British Empire, the United States, and the Soviet Union. But by the mid-1950s the British Empire lost its superpower status, leaving the United States and the Soviet Union as the world's superpowers.[nb 2] The term middle power has emerged for those nations which exercise a degree of global influence, but are insufficient to be decisive on international affairs. Regional powers are those whose influence is generally confined to their region of the world.
Try to answer this question if possible: What are the regional powers according to William T. R. Fox?
Answer: unanswerable


Input: Read this: A very small amount of water vapor inside a light bulb can significantly affect lamp darkening. Water vapor dissociates into hydrogen and oxygen at the hot filament. The oxygen attacks the tungsten metal, and the resulting tungsten oxide particles travel to cooler parts of the lamp. Hydrogen from water vapor reduces the oxide, reforming water vapor and continuing this water cycle. The equivalent of a drop of water distributed over 500,000 lamps will significantly increase darkening. Small amounts of substances such as zirconium are placed within the lamp as a getter to react with any oxygen that may bake out of the lamp components during operation.
Question: Why does water decrease lamp darkening?

Output:
unanswerable
