Q: I know that the answer to the question "What office does Humbert quote Lyons is directly ordained for the salvation of souls?" is in "Humbert of Romans, the master general of the order from 1254 to 1263, was a great administrator, as well as preacher and writer. It was under his tenure as master general that the sisters in the order were given official membership. Humbert was a great lover of languages, and encouraged linguistic studies among the Dominicans, primarily Arabic, because of the missionary work friars were pursuing amongst those led astray or forced to convert by Muslims in the Middle East. He also wanted his friars to reach excellence in their preaching, and this was his most lasting contribution to the order. The growth of the spirituality of young preachers was his first priority. He once cried to his students: "... consider how excellent this office [of preaching] is, because it is apostolic; how useful, because it is directly ordained for the salvation of souls; how perilous, because few have in them, or perform, what the office requires, for it is not without great danger ... , vol. xxv. (Lyon, 1677)". Can you tell me what it is?
A: preaching

Q: I know that the answer to the question "Who was a cost with no benefits?" is in "First, the Yongying system signaled the end of Manchu dominance in Qing military establishment. Although the Banners and Green Standard armies lingered on as a drain on resources, henceforth the Yongying corps became the Qing government's de facto first-line troops. Second, the Yongying corps were financed through provincial coffers and were led by regional commanders, weakening central government's grip on the whole country. Finally, the nature of Yongying command structure fostered nepotism and cronyism amongst its commanders, who laid the seeds of regional warlordism in the first half of the 20th century.". Can you tell me what it is?
A: the Banners and Green Standard

Q: I know that the answer to the question "Nuclear purposes use?" is in "Energy transformations in the universe over time are characterized by various kinds of potential energy that has been available since the Big Bang later being "released" (transformed to more active types of energy such as kinetic or radiant energy) when a triggering mechanism is available. Familiar examples of such processes include nuclear decay, in which energy is released that was originally "stored" in heavy isotopes (such as uranium and thorium), by nucleosynthesis, a process ultimately using the gravitational potential energy released from the gravitational collapse of supernovae, to store energy in the creation of these heavy elements before they were incorporated into the solar system and the Earth. This energy is triggered and released in nuclear fission bombs or in civil nuclear power generation. Similarly, in the case of a chemical explosion, chemical potential energy is transformed to kinetic energy and thermal energy in a very short time. Yet another example is that of a pendulum. At its highest points the kinetic energy is zero and the gravitational potential energy is at maximum. At its lowest point the kinetic energy is at maximum and is equal to the decrease of potential energy. If one (unrealistically) assumes that there is no friction or other losses, the conversion of energy between these processes would be perfect, and the pendulum would continue swinging forever.". Can you tell me what it is?
A: energy

Q: I know that the answer to the question "What is spoken besides Kriol and Portuguese?" is in "14% of the population speaks the official language Portuguese, the language of government and national communication during centuries of colonial rule. 44% speak Kriol, a Portuguese-based creole language, which is effectively a national language of communication among groups. The remainder speak a variety of native African languages unique to ethnicities.". Can you tell me what it is?
A:
a variety of native African languages
