Input: Read this: Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.
Question: How is the brightness of a light changed?

Output: unanswerable

QUES: It has pleased western historians to write of a decline of the Ottoman Empire as though a stable and uncontested polity of that name once existed. The borders did expand and contract but they were always dynamic and always in "question" right from the beginning. The Ottoman Empire was created from the lands of the former eastern Roman Empire on the occasion of the latter's violent demise. The last Roman emperor died fighting hand-to-hand in the streets of his capital, Constantinople, overwhelmed by the Ottoman military, in May, 1453. The victors inherited his remaining territory in the Balkans.

Where was the Roman emperor's capital?
What is the answer?
ANS: Constantinople

QUES: Africa separated from Antarctica in the Jurassic, around 160 Ma, followed by the Indian subcontinent in the early Cretaceous (about 125 Ma). By the end of the Cretaceous, about 66 Ma, Antarctica (then connected to Australia) still had a subtropical climate and flora, complete with a marsupial fauna. In the Eocene epoch, about 40 Ma Australia-New Guinea separated from Antarctica, so that latitudinal currents could isolate Antarctica from Australia, and the first ice began to appear. During the EoceneOligocene extinction event about 34 million years ago, CO2 levels have been found to be about 760 ppm and had been decreasing from earlier levels in the thousands of ppm.
After the division from Australia, what began to appear?

ANS: ice

It is the most widely used vaccine worldwide, with more than 90% of all children being vaccinated. The immunity it induces decreases after about ten years. As tuberculosis is uncommon in most of Canada, the United Kingdom, and the United States, BCG is administered only to those people at high risk. Part of the reasoning against the use of the vaccine is that it makes the tuberculin skin test falsely positive, reducing the test's use in screening. A number of new vaccines are currently in development.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which three countries have a high risk of tuberculosis?
Ah, so.. unanswerable

Question: Emotion, in everyday speech, is any relatively brief conscious experience characterized by intense mental activity and a high degree of pleasure or displeasure. Scientific discourse has drifted to other meanings and there is no consensus on a definition. Emotion is often intertwined with mood, temperament, personality, disposition, and motivation. In some theories, cognition is an important aspect of emotion. Those acting primarily on emotion may seem as if they are not thinking, but mental processes are still essential, particularly in the interpretation of events. For example, the realization of danger and subsequent arousal of the nervous system (e.g. rapid heartbeat and breathing, sweating, muscle tension) is integral to the experience of fear. Other theories, however, claim that emotion is separate from and can precede cognition.
Try to answer this question if possible: Along with sweating and muscle tension, what might be a non-physiological response to danger?
Answer: unanswerable

Context and question: Several Americans, especially Benjamin Franklin and Thomas Jefferson, played a major role in bringing Enlightenment ideas to the New World and in influencing British and French thinkers. Franklin was influential for his political activism and for his advances in physics. The cultural exchange during the Age of Enlightenment ran in both directions across the Atlantic. Thinkers such as Paine, Locke, and Rousseau all take Native American cultural practices as examples of natural freedom. The Americans closely followed English and Scottish political ideas, as well as some French thinkers such as Montesquieu. As deists, they were influenced by ideas of John Toland (16701722) and Matthew Tindal (16561733). During the Enlightenment there was a great emphasis upon liberty, democracy, republicanism and religious tolerance. Attempts to reconcile science and religion resulted in a widespread rejection of prophecy, miracle and revealed religion in preference for Deism especially by Thomas Paine in The Age of Reason and by Thomas Jefferson in his short Jefferson Bible from which all supernatural aspects were removed.
As diests, Americans were influenced by the ideas of which two Enlightenment followers?
Answer:
John Toland (16701722) and Matthew Tindal (16561733)
