Input: Gramophone record
There is a theory that vinyl records can audibly represent higher frequencies than compact discs. According to Red Book specifications, the compact disc has a frequency response of 20 Hz up to 22,050 Hz, and most CD players measure flat within a fraction of a decibel from at least 20 Hz to 20 kHz at full output. Turntable rumble obscures the low-end limit of vinyl but the upper end can be, with some cartridges, reasonably flat within a few decibels to 30 kHz, with gentle roll-off. Carrier signals of Quad LPs popular in the 1970s were at 30 kHz to be out of the range of human hearing. The average human auditory system is sensitive to frequencies from 20 Hz to a maximum of around 20,000 Hz. The upper and lower frequency limits of human hearing vary per person.

What is generally the lowest sound a human can hear?
Output: 20 Hz


Input: Article: Commercial CSP plants were first developed in the 1980s. Since 1985 the eventually 354 MW SEGS CSP installation, in the Mojave Desert of California, is the largest solar power plant in the world. Other large CSP plants include the 150 MW Solnova Solar Power Station and the 100 MW Andasol solar power station, both in Spain. The 250 MW Agua Caliente Solar Project, in the United States, and the 221 MW Charanka Solar Park in India, are the world’s largest photovoltaic plants. Solar projects exceeding 1 GW are being developed, but most of the deployed photovoltaics are in small rooftop arrays of less than 5 kW, which are grid connected using net metering and/or a feed-in tariff. In 2013 solar generated less than 1% of the worlds total grid electricity.

Now answer this question: What are the largest photovoltaic solar power plants?

Output: The 250 MW Agua Caliente Solar Project, in the United States, and the 221 MW Charanka Solar Park in India


Article: Apple did not develop the iPod software entirely in-house, instead using PortalPlayer's reference platform based on two ARM cores. The platform had rudimentary software running on a commercial microkernel embedded operating system. PortalPlayer had previously been working on an IBM-branded MP3 player with Bluetooth headphones. Apple contracted another company, Pixo, to help design and implement the user interface under the direct supervision of Steve Jobs. As development progressed, Apple continued to refine the software's look and feel. Starting with the iPod Mini, the Chicago font was replaced with Espy Sans. Later iPods switched fonts again to Podium Sans—a font similar to Apple's corporate font, Myriad. iPods with color displays then adopted some Mac OS X themes like Aqua progress bars, and brushed metal meant to evoke a combination lock. In 2007, Apple modified the iPod interface again with the introduction of the sixth-generation iPod Classic and third-generation iPod Nano by changing the font to Helvetica and, in most cases, splitting the screen in half by displaying the menus on the left and album artwork, photos, or videos on the right (whichever was appropriate for the selected item).

Question: What software did Apple use as the basis for their iPod software?
Ans: PortalPlayer


Here is a question about this article: During the war, the Seven Nations of Canada were allied with the French. These were Native Americans of the Laurentian valley—the Algonquin, the Abenaki, the Huron, and others. Although the Algonquin tribes and the Seven Nations were not directly concerned with the fate of the Ohio River Valley, they had been victims of the Iroquois Confederation. The Iroquois had encroached on Algonquin territory and pushed the Algonquins west beyond Lake Michigan. Therefore, the Algonquin and the Seven Nations were interested in fighting against the Iroquois. Throughout New England, New York, and the North-west Native American tribes formed differing alliances with the major belligerents. The Iroquois, dominant in what is now Upstate New York, sided with the British but did not play a large role in the war.
What is the answer to this question: How valuable was the Iroquois alliance with Britain?
****
So... The Iroquois, dominant in what is now Upstate New York, sided with the British but did not play a large role in the war


The problem: Answer a question about this article:
The main cause of TB is Mycobacterium tuberculosis, a small, aerobic, nonmotile bacillus. The high lipid content of this pathogen accounts for many of its unique clinical characteristics. It divides every 16 to 20 hours, which is an extremely slow rate compared with other bacteria, which usually divide in less than an hour. Mycobacteria have an outer membrane lipid bilayer. If a Gram stain is performed, MTB either stains very weakly "Gram-positive" or does not retain dye as a result of the high lipid and mycolic acid content of its cell wall. MTB can withstand weak disinfectants and survive in a dry state for weeks. In nature, the bacterium can grow only within the cells of a host organism, but M. tuberculosis can be cultured in the laboratory.
In nature, what "helper" does the MTB bacterium require to grow?
****
The answer: a host organism


The problem: Answer a question about this article:
Cyborg anthropology originated as a sub-focus group within the American Anthropological Association's annual meeting in 1993. The sub-group was very closely related to STS and the Society for the Social Studies of Science. Donna Haraway's 1985 Cyborg Manifesto could be considered the founding document of cyborg anthropology by first exploring the philosophical and sociological ramifications of the term. Cyborg anthropology studies humankind and its relations with the technological systems it has built, specifically modern technological systems that have reflexively shaped notions of what it means to be human beings.
What the sub-group of cyborg anthropology very closely related to, in addition to STS?
****
The answer:
the Society for the Social Studies of Science
