Question: Read this and answer the question

From 2000 to 2009, the AFL had its own developmental league, the af2. The AFL played 22 seasons from 1987 to 2008; internal issues caused the league to cancel its 2009 season, though the af2 did play. Later that year both the AFL and af2 were dissolved and reorganized as a new corporation comprising teams from both leagues, and the AFL returned in 2010. The Arena Football League has its headquarters in Chicago, Illinois.

When was the first AFL season played?
Answer: 1987


Problem: When Link enters the Twilight Realm, the void that corrupts parts of Hyrule, he transforms into a wolf.[h] He is eventually able to transform between his Hylian and wolf forms at will. As a wolf, Link loses the ability to use his sword, shield, or any secondary items; he instead attacks by biting, and defends primarily by dodging attacks. However, "Wolf Link" gains several key advantages in return—he moves faster than he does as a human (though riding Epona is still faster) and digs holes to create new passages and uncover buried items, and has improved senses, including the ability to follow scent trails.[i] He also carries Midna, a small imp-like creature who gives him hints, uses an energy field to attack enemies, helps him jump long distances, and eventually allows Link to "warp" to any of several preset locations throughout the overworld.[j] Using Link's wolf senses, the player can see and listen to the wandering spirits of those affected by the Twilight, as well as hunt for enemy ghosts named Poes.[k]
What does Link transform into when he enters the Twilight Realm?
The answer is the following: Wolf


A new style of wafers composed of gallium-nitride-on-silicon (GaN-on-Si) is being used to produce white LEDs using 200-mm silicon wafers. This avoids the typical costly sapphire substrate in relatively small 100- or 150-mm wafer sizes. The sapphire apparatus must be coupled with a mirror-like collector to reflect light that would otherwise be wasted. It is predicted that by 2020, 40% of all GaN LEDs will be made with GaN-on-Si. Manufacturing large sapphire material is difficult, while large silicon material is cheaper and more abundant. LED companies shifting from using sapphire to silicon should be a minimal investment.
By what year will% of all GaN LEDs be made with gallium-nitride-on-silicon wafers?
2020


Input: Pharmaceutical industry
While highly effective, the requirement for injection limited the use of norepinephrine[clarification needed] and orally active derivatives were sought. A structurally similar compound, ephedrine, was identified by Japanese chemists in the Ma Huang plant and marketed by Eli Lilly as an oral treatment for asthma. Following the work of Henry Dale and George Barger at Burroughs-Wellcome, academic chemist Gordon Alles synthesized amphetamine and tested it in asthma patients in 1929. The drug proved to have only modest anti-asthma effects, but produced sensations of exhilaration and palpitations. Amphetamine was developed by Smith, Kline and French as a nasal decongestant under the trade name Benzedrine Inhaler. Amphetamine was eventually developed for the treatment of narcolepsy, post-encepheletic parkinsonism, and mood elevation in depression and other psychiatric indications. It received approval as a New and Nonofficial Remedy from the American Medical Association for these uses in 1937 and remained in common use for depression until the development of tricyclic antidepressants in the 1960s.

When were tricyclic antidepressants developed?
Output: 1960s


Input: Article: The City of Charleston Fire Department consists over 300 full-time firefighters. These firefighters operate out of 19 companies located throughout the city: 16 engine companies, two tower companies, and one ladder company. Training, Fire Marshall, Operations, and Administration are the divisions of the department. The department operates on a 24/48 schedule and had a Class 1 ISO rating until late 2008, when ISO officially lowered it to Class 3. Russell (Rusty) Thomas served as Fire Chief until June 2008, and was succeeded by Chief Thomas Carr in November 2008.

Now answer this question: How many full time firefighters do Charleston have?

Output: 300


Problem: Computers control functions at many utilities, including coordination of telecommunications, the power grid, nuclear power plants, and valve opening and closing in water and gas networks. The Internet is a potential attack vector for such machines if connected, but the Stuxnet worm demonstrated that even equipment controlled by computers not connected to the Internet can be vulnerable to physical damage caused by malicious commands sent to industrial equipment (in that case uranium enrichment centrifuges) which are infected via removable media. In 2014, the Computer Emergency Readiness Team, a division of the Department of Homeland Security, investigated 79 hacking incidents at energy companies.
What is a potential attack vector for utilities such as the power grid?
The answer is the following:
The Internet
