Problem: Light-emitting diode:

The currentvoltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the applied voltage exceeds the LED's forward voltage drop by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant-current power supplies to keep the current below the LED's maximum current rating. Since most common power sources (batteries, mains) are constant-voltage sources, most LED fixtures must include a power converter, at least a current-limiting resistor. However, the high resistance of three-volt coin cells combined with the high differential resistance of nitride-based LEDs makes it possible to power such an LED from such a coin cell without an external resistor.

What feature do no LED fixtures need to have?

Problem: The committee considered an eight-bit code, since eight bits (octets) would allow two four-bit patterns to efficiently encode two digits with binary-coded decimal. However, it would require all data transmission to send eight bits when seven could suffice. The committee voted to use a seven-bit code to minimize costs associated with data transmission. Since perforated tape at the time could record eight bits in one position, it also allowed for a parity bit for error checking if desired.:217, 2365 Eight-bit machines (with octets as the native data type) that did not use parity checking typically set the eighth bit to 0.
What did seven-bit machines that did not use parity typically set the eight bit to?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1952, Thomas J. Watson, Jr., published the company's first written equal opportunity policy letter, one year before the U.S. Supreme Court decision in Brown vs. Board of Education and 11 years before the Civil Rights Act of 1964. In 1961, IBM's nondiscrimination policy was expanded to include sex, national origin, and age. The following year, IBM hosted its first Invention Award Dinner honoring 34 outstanding IBM inventors; and in 1963, the company named the first eight IBM Fellows in a new Fellowship Program that recognizes senior IBM scientists, engineers and other professionals for outstanding technical achievements.
In what year was IBM's first equal opportunity policy letter published?
A: 1952

Context and question: Various industrial businesses are located in Hannover. The Volkswagen Commercial Vehicles Transporter (VWN) factory at Hannover-Stocken is the biggest employer in the region and operates a huge plant at the northern edge of town adjoining the Mittellandkanal and Motorway A2. Jointly with a factory of German tire and automobile parts manufacturer Continental AG, they have a coal-burning power plant. Continental AG, founded in Hanover in 1871, is one of the city's major companies, as is Sennheiser. Since 2008 a take-over is in progress: the Schaeffler Group from Herzogenaurach (Bavaria) holds the majority of the stock but were required due to the financial crisis to deposit the options as securities at banks. TUI AG has its HQ in Hanover. Hanover is home to many insurance companies, many of which operate only in Germany. One major global reinsurance company is Hannover Re, whose headquarters are east of the city centre.
What part of town is the plant owned by VWN located in?
Answer: northern edge of town

Question: Sacrifice to deities of the heavens (di superi, "gods above") was performed in daylight, and under the public gaze. Deities of the upper heavens required white, infertile victims of their own sex: Juno a white heifer (possibly a white cow); Jupiter a white, castrated ox (bos mas) for the annual oath-taking by the consuls. Di superi with strong connections to the earth, such as Mars, Janus, Neptune and various genii including the Emperor's were offered fertile victims. After the sacrifice, a banquet was held; in state cults, the images of honoured deities took pride of place on banqueting couches and by means of the sacrificial fire consumed their proper portion (exta, the innards). Rome's officials and priests reclined in order of precedence alongside and ate the meat; lesser citizens may have had to provide their own.
Is there an answer to this question: What event was held after the sacrifice?

Answer: banquet

Problem: Xbox 360:

Xbox Live Arcade is an online service operated by Microsoft that is used to distribute downloadable video games to Xbox and Xbox 360 owners. In addition to classic arcade games such as Ms. Pac-Man, the service offers some new original games like Assault Heroes. The Xbox Live Arcade also features games from other consoles, such as the PlayStation game Castlevania: Symphony of the Night and PC games such as Zuma. The service was first launched on November 3, 2004, using a DVD to load, and offered games for about US$5 to $15. Items are purchased using Microsoft Points, a proprietary currency used to reduce credit card transaction charges. On November 22, 2005, Xbox Live Arcade was re-launched with the release of the Xbox 360, in which it was now integrated with the Xbox 360's dashboard. The games are generally aimed toward more casual gamers; examples of the more popular titles are Geometry Wars, Street Fighter II' Hyper Fighting, and Uno. On March 24, 2010, Microsoft introduced the Game Room to Xbox Live. Game Room is a gaming service for Xbox 360 and Microsoft Windows that lets players compete in classic arcade and console games in a virtual arcade.

How much was Castlevania: Symphony sold for?
