Input: Black people
Being identified as either "black" or "white" in Australia during the 19th and early 20th centuries was critical in one's employment and social prospects. Various state-based Aboriginal Protection Boards were established which had virtually complete control over the lives of Indigenous Australians – where they lived, their employment, marriage, education and included the power to separate children from their parents. Aborigines were not allowed to vote and were often confined to reserves and forced into low paid or effectively slave labour. The social position of mixed-race or "half-caste" individuals varied over time. A 1913 report by Sir Baldwin Spencer states that:

What year was his report from?
Output: 1913

Input: Anti-aircraft warfare
The essence of air defence is to detect hostile aircraft and destroy them. The critical issue is to hit a target moving in three-dimensional space; an attack must not only match these three coordinates, but must do so at the time the target is at that position. This means that projectiles either have to be guided to hit the target, or aimed at the predicted position of the target at the time the projectile reaches it, taking into account speed and direction of both the target and the projectile.

What is the first purpose of air defence?
Output: detect hostile aircraft

Input: Miami
Miami is also considered a "hot spot" for dance music, Freestyle, a style of dance music popular in the 80's and 90's heavily influenced by Electro, hip-hop, and disco. Many popular Freestyle acts such as Pretty Tony, Debbie Deb, Stevie B, and Exposé, originated in Miami. Indie/folk acts Cat Power and Iron & Wine are based in the city, while alternative hip hop artist Sage Francis, electro artist Uffie, and the electroclash duo Avenue D were born in Miami, but musically based elsewhere. Also, ska punk band Against All Authority is from Miami, and rock/metal bands Nonpoint and Marilyn Manson each formed in neighboring Fort Lauderdale. Cuban American female recording artist, Ana Cristina, was born in Miami in 1985.

What genre of music does Uffie perform?
Output: electro

Input: Capacitor
Several solid dielectrics are available, including paper, plastic, glass, mica and ceramic materials. Paper was used extensively in older devices and offers relatively high voltage performance. However, it is susceptible to water absorption, and has been largely replaced by plastic film capacitors. Plastics offer better stability and ageing performance, which makes them useful in timer circuits, although they may be limited to low operating temperatures and frequencies. Ceramic capacitors are generally small, cheap and useful for high frequency applications, although their capacitance varies strongly with voltage and they age poorly. They are broadly categorized as class 1 dielectrics, which have predictable variation of capacitance with temperature or class 2 dielectrics, which can operate at higher voltage. Glass and mica capacitors are extremely reliable, stable and tolerant to high temperatures and voltages, but are too expensive for most mainstream applications. Electrolytic capacitors and supercapacitors are used to store small and larger amounts of energy, respectively, ceramic capacitors are often used in resonators, and parasitic capacitance occurs in circuits wherever the simple conductor-insulator-conductor structure is formed unintentionally by the configuration of the circuit layout.

What is one type of reliable capacitor that is resistant to temperature and voltage changes?
Output:
Glass
