Input: Film speed
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.

What determines the effect on the emulsion after exposure?
Output: the amount of light energy that reaches the film

Input: Late Middle Ages
At the end of the Late Middle Ages, professional actors began to appear in England and Europe. Richard III and Henry VII both maintained small companies of professional actors. Their plays were performed in the Great Hall of a nobleman's residence, often with a raised platform at one end for the audience and a "screen" at the other for the actors. Also important were Mummers' plays, performed during the Christmas season, and court masques. These masques were especially popular during the reign of Henry VIII who had a House of Revels built and an Office of Revels established in 1545.

Who performed the seasonal Christmas plays?
Output: Mummers

Input: Hellenistic period
Magic was practiced widely, and these too, were a continuation from earlier times. Throughout the Hellenistic world, people would consult oracles, and use charms and figurines to deter misfortune or to cast spells. Also developed in this era was the complex system of astrology, which sought to determine a person's character and future in the movements of the sun, moon, and planets. Astrology was widely associated with the cult of Tyche (luck, fortune), which grew in popularity during this period.

How would people ward off misfortune in Hellenistic times?
Output: charms

Input: Race (human categorization)
In an attempt to provide general descriptions that may facilitate the job of law enforcement officers seeking to apprehend suspects, the United States FBI employs the term "race" to summarize the general appearance (skin color, hair texture, eye shape, and other such easily noticed characteristics) of individuals whom they are attempting to apprehend. From the perspective of law enforcement officers, it is generally more important to arrive at a description that will readily suggest the general appearance of an individual than to make a scientifically valid categorization by DNA or other such means. Thus, in addition to assigning a wanted individual to a racial category, such a description will include: height, weight, eye color, scars and other distinguishing characteristics.

What does a description of a wanted individual include beyond their racial category?
Output:
height, weight, eye color, scars and other distinguishing characteristics.
