Input: Read this: Thermodynamics divides energy transformation into two kinds: reversible processes and irreversible processes. An irreversible process is one in which energy is dissipated (spread) into empty energy states available in a volume, from which it cannot be recovered into more concentrated forms (fewer quantum states), without degradation of even more energy. A reversible process is one in which this sort of dissipation does not happen. For example, conversion of energy from one type of potential field to another, is reversible, as in the pendulum system described above. In processes where heat is generated, quantum states of lower energy, present as possible excitations in fields between atoms, act as a reservoir for part of the energy, from which it cannot be recovered, in order to be converted with 100% efficiency into other forms of energy. In this case, the energy must partly stay as heat, and cannot be completely recovered as usable energy, except at the price of an increase in some other kind of heat-like increase in disorder in quantum states, in the universe (such as an expansion of matter, or a randomisation in a crystal).
Question: A reversible process is one in which this happens.

Output: unanswerable


Input: Read this: Literacy rate in the Muslim world varies. Some members such as Kuwait, Kazakhstan, Tajikistan and Turkmenistan have over 97% literacy rates, whereas literacy rates are the lowest in Mali, Afghanistan, Chad and parts of Africa. In 2015, the International Islamic News Agency reported that nearly 37% of the population of the Muslim world is unable to read or write, basing that figure on reports from the Organisation of Islamic Cooperation and the Islamic Educational, Scientific and Cultural Organization.
Question: What organizations studied literacy in the Muslim World in 2015?

Output: Organisation of Islamic Cooperation and the Islamic Educational, Scientific and Cultural Organization


Input: Read this: Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722–481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.
Question: What element was used in the production of wrought iron?

Output: oxygen


Input: Read this: The Romans are known for the great number of deities they honored, a capacity that earned the mockery of early Christian polemicists. The presence of Greeks on the Italian peninsula from the beginning of the historical period influenced Roman culture, introducing some religious practices that became as fundamental as the cult of Apollo. The Romans looked for common ground between their major gods and those of the Greeks (interpretatio graeca), adapting Greek myths and iconography for Latin literature and Roman art. Etruscan religion was also a major influence, particularly on the practice of augury.
Question: What religion influenced augury for the Romans?

Output:
Etruscan
