Input: Read this: Bacteria are further divided into lithotrophs that use inorganic electron donors and organotrophs that use organic compounds as electron donors. Chemotrophic organisms use the respective electron donors for energy conservation (by aerobic/anaerobic respiration or fermentation) and biosynthetic reactions (e.g., carbon dioxide fixation), whereas phototrophic organisms use them only for biosynthetic purposes. Respiratory organisms use chemical compounds as a source of energy by taking electrons from the reduced substrate and transferring them to a terminal electron acceptor in a redox reaction. This reaction releases energy that can be used to synthesise ATP and drive metabolism. In aerobic organisms, oxygen is used as the electron acceptor. In anaerobic organisms other inorganic compounds, such as nitrate, sulfate or carbon dioxide are used as electron acceptors. This leads to the ecologically important processes of denitrification, sulfate reduction, and acetogenesis, respectively.
Question: What type of electron donors organotrophs use?

Output: organic compounds


QUES: In the early 1980s, rapidly rising oil revenues enabled the government to finance large-scale development projects with GDP growth averaging 5% annually, one of the highest rates in Africa. The government has mortgaged a substantial portion of its petroleum earnings, contributing to a shortage of revenues. January 12, 1994 devaluation of Franc Zone currencies by 50% resulted in inflation of 46% in 1994, but inflation has subsided since.

QUES: The bulk of Masonic ritual consists of degree ceremonies. Candidates for Freemasonry are progressively initiated into Freemasonry, first in the degree of Entered Apprentice. Some time later, in a separate ceremony, they will be passed to the degree of Fellowcraft, and finally they will be raised to the degree of Master Mason. In all of these ceremonies, the candidate is entrusted with passwords, signs and grips peculiar to his new rank. Another ceremony is the annual installation of the Master and officers of the Lodge. In some jurisdictions Installed Master is valued as a separate rank, with its own secrets to distinguish its members. In other jurisdictions, the grade is not recognised, and no inner ceremony conveys new secrets during the installation of a new Master of the Lodge.
What quarterly ceremony do Freemasons have?

ANS: unanswerable


He was General Secretary (later Chairman of the Presidium) of the League of Communists of Yugoslavia (1939–80), and went on to lead the World War II Yugoslav guerrilla movement, the Partisans (1941–45). After the war, he was the Prime Minister (1944–63), President (later President for Life) (1953–80) of the Socialist Federal Republic of Yugoslavia (SFRY). From 1943 to his death in 1980, he held the rank of Marshal of Yugoslavia, serving as the supreme commander of the Yugoslav military, the Yugoslav People's Army (JNA). With a highly favourable reputation abroad in both Cold War blocs, Josip Broz Tito received some 98 foreign decorations, including the Legion of Honour and the Order of the Bath.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): During what years did Tito lead the Partisans?
Ah, so.. 1941–45


Question: The area's many colleges and universities are active in college athletics. Four NCAA Division I members play in the city—Boston College, Boston University, Harvard University, and Northeastern University. Of the four, only Boston College participates in college football at the highest level, the Football Bowl Subdivision. Harvard participates in the second-highest level, the Football Championship Subdivision.
Try to answer this question if possible: How many NCAA Division I members play in Boston?
Answer: four


Input: Read this: Hunting big game typically requires a "tag" for each animal harvested. Tags must be purchased in addition to the hunting license, and the number of tags issued to an individual is typically limited. In cases where there are more prospective hunters than the quota for that species, tags are usually assigned by lottery. Tags may be further restricted to a specific area, or wildlife management unit. Hunting migratory waterfowl requires a duck stamp from the Fish and Wildlife Service in addition to the appropriate state hunting license.
Question: A wildlife management unit is a place where what may be restricted to?

Output:
Tags
