Input: Incandescent light bulb
Most light bulbs have either clear or coated glass. The coated glass bulbs have a white powdery substance on the inside called kaolin. Kaolin, or kaolinite, is a white, chalky clay in a very fine powder form, that is blown in and electrostatically deposited on the interior of the bulb. It diffuses the light emitted from the filament, producing a more gentle and evenly distributed light. Manufacturers may add pigments to the kaolin to adjust the characteristics of the final light emitted from the bulb. Kaolin diffused bulbs are used extensively in interior lighting because of their comparatively gentle light. Other kinds of colored bulbs are also made, including the various colors used for "party bulbs", Christmas tree lights and other decorative lighting. These are created by coloring the glass with a dopant; which is often a metal like cobalt (blue) or chromium (green). Neodymium-containing glass is sometimes used to provide a more natural-appearing light.

What is the effect of a kaolin coating on the light cast?
Output: a more gentle and evenly distributed light

Input: United States dollar
The colloquialism "buck"(s) (much like the British word "quid"(s, pl) for the pound sterling) is often used to refer to dollars of various nations, including the U.S. dollar. This term, dating to the 18th century, may have originated with the colonial leather trade. It may also have originated from a poker term. "Greenback" is another nickname originally applied specifically to the 19th century Demand Note dollars created by Abraham Lincoln to finance the costs of the Civil War for the North. The original note was printed in black and green on the back side. It is still used to refer to the U.S. dollar (but not to the dollars of other countries). Other well-known names of the dollar as a whole in denominations include "greenmail", "green" and "dead presidents" (the last because deceased presidents are pictured on most bills).

What was the nickname given to the Demand Note dollars that were used to finance the Civil War?
Output: Greenback

Input: Brigham Young University
Franklin S. Harris was appointed the university's president in 1921. He was the first BYU president to have a doctoral degree. Harris made several important changes to the school, reorganizing it into a true university, whereas before, its organization had remnants of the Academy days. At the beginning of his tenure, the school was not officially recognized as a university by any accreditation organization. By the end of his term, the school was accredited under all major accrediting organizations at the time. He was eventually replaced by Howard S. McDonald, who received his doctorate from the University of California. When he first received the position, the Second World War had just ended, and thousands of students were flooding into BYU. By the end of his stay, the school had grown nearly five times to an enrollment of 5,440 students. The university did not have the facilities to handle such a large influx, so he bought part of an Air Force Base in Ogden, Utah and rebuilt it to house some of the students. The next president, Ernest L. Wilkinson, also oversaw a period of intense growth, as the school adopted an accelerated building program. Wilkinson was responsible for the building of over eighty structures on the campus, many of which still stand. During his tenure, the student body increased six times, making BYU the largest private school at the time. The quality of the students also increased, leading to higher educational standards at the school. Finally, Wilkinson reorganized the LDS Church units on campus, with ten stakes and over 100 wards being added during his administration.

What type of degree did BYU's appointed president of 1921, Franklin S. Harris have that no former BYU president had?
Output: doctoral

Input: Anti-aircraft warfare
Smaller boats and ships typically have machine-guns or fast cannons, which can often be deadly to low-flying aircraft if linked to a radar-directed fire-control system radar-controlled cannon for point defence. Some vessels like Aegis cruisers are as much a threat to aircraft as any land-based air defence system. In general, naval vessels should be treated with respect by aircraft, however the reverse is equally true. Carrier battle groups are especially well defended, as not only do they typically consist of many vessels with heavy air defence armament but they are also able to launch fighter jets for combat air patrol overhead to intercept incoming airborne threats.

What type of ships are particularly well defended?
Output:
Carrier battle groups
