Input: Read this: Dreyfus writes that after the Phagmodrupa lost its centralizing power over Tibet in 1434, several attempts by other families to establish hegemonies failed over the next two centuries until 1642 with the 5th Dalai Lama's effective hegemony over Tibet.
Question: What did the other families fail to establish?

Output: hegemonies

QUES: From roughly 115 to 60 BC, Han forces fought the Xiongnu over control of the oasis city-states in the Tarim Basin. Han was eventually victorious and established the Protectorate of the Western Regions in 60 BC, which dealt with the region's defense and foreign affairs. The Han also expanded southward. The naval conquest of Nanyue in 111 BC expanded the Han realm into what are now modern Guangdong, Guangxi, and northern Vietnam. Yunnan was brought into the Han realm with the conquest of the Dian Kingdom in 109 BC, followed by parts of the Korean Peninsula with the colonial establishments of Xuantu Commandery and Lelang Commandery in 108 BC. In China's first known nationwide census taken in 2 AD, the population was registered as having 57,671,400 individuals in 12,366,470 households.

When was the first national census taken in China?
What is the answer?
ANS: 2 AD

QUES: In quantum mechanics, energy is defined in terms of the energy operator as a time derivative of the wave function. The Schrodinger equation equates the energy operator to the full energy of a particle or a system. Its results can be considered as a definition of measurement of energy in quantum mechanics. The Schrodinger equation describes the space- and time-dependence of a slowly changing (non-relativistic) wave function of quantum systems. The solution of this equation for a bound system is discrete (a set of permitted states, each characterized by an energy level) which results in the concept of quanta. In the solution of the Schrodinger equation for any oscillator (vibrator) and for electromagnetic waves in a vacuum, the resulting energy states are related to the frequency by Planck's relation: (where is Planck's constant and the frequency). In the case of an electromagnetic wave these energy states are called quanta of light or photons.
What describes the space-and-time dependence of a slowly changing wave function of quantum systems?

ANS: The Schrodinger equation

Publius Vergilius Maro (Classical Latin: [pu.bl.s wr.l.s ma.ro]; October 15, 70 BC September 21, 19 BC), usually called Virgil or Vergil /vrdl/ in English, was an ancient Roman poet of the Augustan period. He is known for three major works of Latin literature, the Eclogues (or Bucolics), the Georgics, and the epic Aeneid. A number of minor poems, collected in the Appendix Vergiliana, are sometimes attributed to him.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which major Latin epic is Virgil known for?
Ah, so.. Aeneid

Question: The March 1906 Scientific American article by American pioneer William E. Meacham explained the basic principle of hydrofoils and hydroplanes. Bell considered the invention of the hydroplane as a very significant achievement. Based on information gained from that article he began to sketch concepts of what is now called a hydrofoil boat. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. This led him and Bell to the development of practical hydrofoil watercraft.
Try to answer this question if possible: What did Bell start drawing after reading the article?
Answer: hydrofoil boat

Context and question: The vicereine Germaine of Foix brutally repressed the uprising and its leaders, and this accelerated the authoritarian centralisation of the government of Charles I. Queen Germaine favoured harsh treatment of the agermanats. She is thought to have signed the death warrants of 100 former rebels personally, and sources indicate that as many as 800 executions may have occurred. The agermanats are comparable to the comuneros of neighbouring Castile, who fought a similar revolt against Charles from 15201522.
Up to how many executions took place after the agermanats' revolt?
Answer:
800
