Problem: USB:

USB is a serial bus, using four shielded wires for the USB 2.0 variant: two for power (VBUS and GND), and two for differential data signals (labelled as D+ and D− in pinouts). Non-Return-to-Zero Inverted (NRZI) encoding scheme is used for transferring data, with a sync field to synchronize the host and receiver clocks. D+ and D− signals are transmitted on a twisted pair, providing half-duplex data transfers for USB 2.0. Mini and micro connectors have their GND connections moved from pin #4 to pin #5, while their pin #4 serves as an ID pin for the On-The-Go host/client identification.

What kind of wires does the USB 2.0 variant use?

A: four shielded wires


Problem: While West had encountered controversy a year prior when he stormed out of the American Music Awards of 2004 after losing Best New Artist, the rapper's first large-scale controversy came just days following Late Registration's release, during a benefit concert for Hurricane Katrina victims. In September 2005, NBC broadcast A Concert for Hurricane Relief, and West was a featured speaker. When West was presenting alongside actor Mike Myers, he deviated from the prepared script. Myers spoke next and continued to read the script. Once it was West's turn to speak again, he said, "George Bush doesn't care about black people." West's comment reached much of the United States, leading to mixed reactions; President Bush would later call it one of the most "disgusting moments" of his presidency. West raised further controversy in January 2006 when he posed on the cover of Rolling Stone wearing a crown of thorns.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry dozens of aircraft, including fighter jets and helicopters. As of 3 March 2016, there are thirty-seven active aircraft carriers in the world within twelve navies. The United States Navy has 10 large nuclear-powered carriers (known as supercarriers, carrying up to 90 aircraft each), the largest carriers in the world; the total deckspace is over twice that of all other nations' combined. As well as the supercarrier fleet, the US Navy has nine amphibious assault ships used primarily for helicopters (sometimes called helicopter carriers); these can also carry up to 25 fighter jets, and in some cases, are as large as some other nations' fixed-wing carriers.
What is another name for the 10 large nuclear-powered carriers operated by the U.S. Navy?
A: supercarriers


Context and question: Brigham Young University's origin can be traced back to 1862 when a man named Warren Dusenberry started a Provo school in a prominent adobe building called Cluff Hall, which was located in the northeast corner of 200 East and 200 North. On October 16, 1875, Brigham Young, then president of the LDS Church, personally purchased the Lewis Building after previously hinting that a school would be built in Draper, Utah in 1867. Hence, October 16, 1875 is commonly held as BYU's founding date. Said Young about his vision: "I hope to see an Academy established in Provo... at which the children of the Latter-day Saints can receive a good education unmixed with the pernicious atheistic influences that are found in so many of the higher schools of the country."
What type of influences did Brigham Young hope to avoid with BYU?
Answer: atheistic


Question: Portugal’s national energy transmission company, Redes Energéticas Nacionais (REN), uses sophisticated modeling to predict weather, especially wind patterns, and computer programs to calculate energy from the various renewable-energy plants. Before the solar/wind revolution, Portugal had generated electricity from hydropower plants on its rivers for decades. New programs combine wind and water: wind-driven turbines pump water uphill at night, the most blustery period; then the water flows downhill by day, generating electricity, when consumer demand is highest. Portugal’s distribution system is also now a two-way street. Instead of just delivering electricity, it draws electricity from even the smallest generators, like rooftop solar panels. The government aggressively encouraged such contributions by setting a premium price for those who buy rooftop-generated solar electricity.
Is there an answer to this question: Through what renewable resource had Portugal generated electricity before the solar/wind revolution?

Answer: hydropower plants on its rivers


QUES: Ecuador was the site of many indigenous cultures, and civilizations of different proportions. An early sedentary culture, known as the Valdivia culture, developed in the coastal region, while the Caras and the Quitus unified to form an elaborate civilization that ended at the birth of the Capital Quito. The Cañaris near Cuenca were the most advanced, and most feared by the Inca, due to their fierce resistance to the Incan expansion. Their architecture remains were later destroyed by Spaniards and the Incas.

What was Ecuador the site of?
