Input: Read this: In 1930, Paul Dirac proposed a model of the vacuum as an infinite sea of particles possessing negative energy, called the Dirac sea. This theory helped refine the predictions of his earlier formulated Dirac equation, and successfully predicted the existence of the positron, confirmed two years later. Werner Heisenberg's uncertainty principle formulated in 1927, predict a fundamental limit within which instantaneous position and momentum, or energy and time can be measured. This has far reaching consequences on the "emptiness" of space between particles. In the late 20th century, so-called virtual particles that arise spontaneously from empty space were confirmed.
Question: What did Heisenberg call the particles with negative energy inside a vacuum?

Output: unanswerable

Input: Read this: The quarklepton definition of ordinary matter, however, identifies not only the elementary building blocks of matter, but also includes composites made from the constituents (atoms and molecules, for example). Such composites contain an interaction energy that holds the constituents together, and may constitute the bulk of the mass of the composite. As an example, to a great extent, the mass of an atom is simply the sum of the masses of its constituent protons, neutrons and electrons. However, digging deeper, the protons and neutrons are made up of quarks bound together by gluon fields (see dynamics of quantum chromodynamics) and these gluons fields contribute significantly to the mass of hadrons. In other words, most of what composes the "mass" of ordinary matter is due to the binding energy of quarks within protons and neutrons. For example, the sum of the mass of the three quarks in a nucleon is approximately 7001125000000000000♠️12.5 MeV/c2, which is low compared to the mass of a nucleon (approximately 7002938000000000000♠️938 MeV/c2). The bottom line is that most of the mass of everyday objects comes from the interaction energy of its elementary components.
Question: Most of the mass of binding energy is due to what?

Output: unanswerable

Input: Read this: The Palacio do Planalto is the official workplace of the President of Brazil. It is located at the Praca dos Tres Poderes in Brasilia. As the seat of government, the term "Planalto" is often used as a metonym for the executive branch of government. The main working office of the President of the Republic is in the Palacio do Planalto. The President and his or her family do not live in it, rather in the official residence, the Palacio da Alvorada. Besides the President, senior advisors also have offices in the "Planalto," including the Vice-President of Brazil and the Chief of Staff. The other Ministries are along the Esplanada dos Ministerios. The architect of the Palacio do Planalto was Oscar Niemeyer, creator of most of the important buildings in Brasilia. The idea was to project an image of simplicity and modernity using fine lines and waves to compose the columns and exterior structures. The Palace is four stories high, and has an area of 36,000 m2. Four other adjacent buildings are also part of the complex.
Question: Who also has offices in the Alvorada?

Output: unanswerable

Input: Read this: The centuries-long geopolitical and ideological rivalry between Safavid Iran and the neighboring Ottoman Empire, led to numerous OttomanPersian Wars. The Safavid Era peaked in the reign of Abbas the Great, 15871629, surpassing their Ottoman arch rivals in strength, and making the empire a leading hub in Western Eurasia for the sciences and arts. The Safavid Era saw the start of mass integration from Caucasian populations into new layers of the society of Iran, as well as mass resettlement of them within the heartlands of Iran, playing a pivotal role in the history of Iran for centuries onwards. Following a gradual decline in the late 1600s and early 1700s, which was caused by the internal conflicts, the continuous wars with the Ottomans, and the foreign interference (most notably the Russian interference), the Safavid rule was ended by the Pashtun rebels who besieged Isfahan and defeated Soltan Hosein in 1722.
Question: Who ended Safavid power in Iran in 1722?

Output:
Pashtun rebels
