Input: Read this: Idealist notions took a strong hold among physicists of the early 20th century confronted with the paradoxes of quantum physics and the theory of relativity. In The Grammar of Science, Preface to the 2nd Edition, 1900, Karl Pearson wrote, "There are many signs that a sound idealism is surely replacing, as a basis for natural philosophy, the crude materialism of the older physicists." This book influenced Einstein's regard for the importance of the observer in scientific measurements[citation needed]. In § 5 of that book, Pearson asserted that "...science is in reality a classification and analysis of the contents of the mind...." Also, "...the field of science is much more consciousness than an external world."
Question: What did Einstein say science is?

Output: unanswerable


Input: Read this: According to the 2011 Census, 81.0% of the Portuguese population are Roman Catholic. The country has small Protestant, Latter-day Saint, Muslim, Hindu, Sikh, Eastern Orthodox Church, Jehovah's Witnesses, Baha'i, Buddhist, Jewish and Spiritist communities. Influences from African Traditional Religion and Chinese Traditional Religion are also felt among many people, particularly in fields related with Traditional Chinese Medicine and African Witch Doctors. Some 6.8% of the population declared themselves to be non-religious, and 8.3% did not give any answer about their religion.
Question: What other religious communities exist in Portugal?

Output: Protestant, Latter-day Saint, Muslim, Hindu, Sikh, Eastern Orthodox Church, Jehovah's Witnesses, Baha'i, Buddhist, Jewish and Spiritist


Input: Read this: After the end of the late Middle Ages period, the Renaissance would spread unevenly over continental Europe from the southern European region. The intellectual transformation of the Renaissance is viewed as a bridge between the Middle Ages and the Modern era. Europeans would later begin an era of world discovery. Combined with the influx of classical ideas was the invention of printing which facilitated dissemination of the printed word and democratized learning. These two things would lead to the Protestant Reformation. Europeans also discovered new trading routes, as was the case with Columbus’s travel to the Americas in 1492, and Vasco da Gama’s circumnavigation of Africa and India in 1498. Their discoveries strengthened the economy and power of European nations.
Question: What was discovered as the result of both Columbus' and da Gama's voyages?

Output: new trading routes


Input: Read this: The brushless wound-rotor synchronous doubly-fed (BWRSDF) machine is the only electric machine with a truly dual ported transformer circuit topology (i.e., both ports independently excited with no short-circuited port). The dual ported transformer circuit topology is known to be unstable and requires a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set. If a precision means were available to instantaneously control torque angle and slip for synchronous operation during motoring or generating while simultaneously providing brushless power to the rotor winding set, the active current of the BWRSDF machine would be independent of the reactive impedance of the transformer circuit and bursts of torque significantly higher than the maximum operating torque and far beyond the practical capability of any other type of electric machine would be realizable. Torque bursts greater than eight times operating torque have been calculated.
Question: What is a brushless wound-rotor?

Output:
both ports independently excited with no short-circuited port
