Input: Read this: Uranium was also used in photographic chemicals (especially uranium nitrate as a toner), in lamp filaments for stage lighting bulbs, to improve the appearance of dentures, and in the leather and wood industries for stains and dyes. Uranium salts are mordants of silk or wool. Uranyl acetate and uranyl formate are used as electron-dense "stains" in transmission electron microscopy, to increase the contrast of biological specimens in ultrathin sections and in negative staining of viruses, isolated cell organelles and macromolecules.
Question: What light bulbs don't use lamp filaments containing uranium?

Output: unanswerable


QUES: India's cotton-processing sector gradually declined during British expansion in India and the establishment of colonial rule during the late 18th and early 19th centuries. This was largely due to aggressive colonialist mercantile policies of the British East India Company, which made cotton processing and manufacturing workshops in India uncompetitive. Indian markets were increasingly forced to supply only raw cotton and, by British-imposed law, to purchase manufactured textiles from Britain.[citation needed]

What cotton products did Indian law mandate that India was allowed to sell?
What is the answer?
ANS: unanswerable


QUES: Title VII was perhaps the most controversial of the entire bill. Many conservatives accused it of advocating a de facto quota system, and claimed unconstitutionality as it attempts to regulate the workplace. Minnesota Senator Hubert Humphrey corrected this notion: "there is nothing in [Title VII] that will give power to the Commission to require hiring, firing, and promotion to meet a racial 'quota.' [. . .] Title VII is designed to encourage the hiring on basis of ability and qualifications, not race or religion." Title VII prohibits discrimination. Humphrey was the silent hero of the bill's passing through Congress. He pledged that the bill required no quotas, just nondiscrimination. Doing so, he convinced many pro-business Republicans, including Senate Minority Leader Everett Dirksen (IL) to support Title VII.:78–80
What did critics claim that Title VII advocate?

ANS: a de facto quota system


The Supermarine Spitfire was designed and developed in Southampton, evolving from the Schneider trophy-winning seaplanes of the 1920s and 1930s. Its designer, R J Mitchell, lived in the Portswood area of Southampton, and his house is today marked with a blue plaque. Heavy bombing of the factory in September 1940 destroyed it as well as homes in the vicinity, killing civilians and workers. World War II hit Southampton particularly hard because of its strategic importance as a major commercial port and industrial area. Prior to the Invasion of Europe, components for a Mulberry harbour were built here. After D-Day, Southampton docks handled military cargo to help keep the Allied forces supplied, making it a key target of Luftwaffe bombing raids until late 1944. Southampton docks was featured in the television show 24: Live Another Day in Day 9: 9:00 p.m. – 10:00 p.m.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which forces did Southampton supply after D-Day that made it a target for many Luftwaffe air raids?
Ah, so.. Allied forces


Question: Since 2001, Miami has been undergoing a large building boom with more than 50 skyscrapers rising over 400 feet (122 m) built or currently under construction in the city. Miami's skyline is ranked third-most impressive in the U.S., behind New York City and Chicago, and 19th in the world according to the Almanac of Architecture and Design. The city currently has the eight tallest (as well as thirteen of the fourteen tallest) skyscrapers in the state of Florida, with the tallest being the 789-foot (240 m) Four Seasons Hotel & Tower.
Try to answer this question if possible: How many 400+ foot skyscrapers have been built or are in the process of being built in Miami since 2001?
Answer: 50


Question: The mid-1970s saw the introduction of dbx-encoded records, again for the audiophile niche market. These were completely incompatible with standard record playback preamplifiers, relying on the dbx compandor encoding/decoding scheme to greatly increase dynamic range (dbx encoded disks were recorded with the dynamic range compressed by a factor of two in dB: quiet sounds were meant to be played back at low gain and loud sounds were meant to be played back at high gain, via automatic gain control in the playback equipment; this reduced the effect of surface noise on quiet passages). A similar and very short-lived scheme involved using the CBS-developed "CX" noise reduction encoding/decoding scheme.
Try to answer this question if possible: When were DBX recordings released?
Answer:
mid-1970s
