Problem: Nintendo Entertainment System:

In the UK, Italy and Australia which share the PAL A region, two versions of the NES were released; the "Mattel Version" and "NES Version". When the NES was first released in those countries, it was distributed by Mattel and Nintendo decided to use a lockout chip specific to those countries, different from the chip used in other European countries. When Nintendo took over European distribution in 1990, they produced consoles that were then labelled "NES Version"; therefore, the only differences between the two are the text on the front flap and texture on the top/bottom of the casing.

 When did Nintendo take over Asian distribution?

Problem: New Haven Harbor is home to the Port of New Haven, a deep-water seaport with three berths capable of hosting vessels and barges as well as the facilities required to handle break bulk cargo. The port has the capacity to load 200 trucks a day from the ground or via loading docks. Rail transportation access is available, with a private switch engine for yard movements and private siding for loading and unloading. Approximately 400,000 square feet (40,000 m2) of inside storage and 50 acres (200,000 m2) of outside storage are available at the site. Five shore cranes with a 250-ton capacity and 26 forklifts, each with a 26-ton capacity, are also available.
In terms of scale how big is the harbor?

Answer: 400,000 square feet


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Training in the U.S. Army is generally divided into two categories – individual and collective. Basic training consists of 10 weeks for most recruits followed by Advanced Individualized Training (AIT) where they receive training for their military occupational specialties (MOS). Some individuals MOSs range anywhere from 14–20 weeks of One Station Unit Training (OSUT), which combines Basic Training and AIT. The length of AIT school varies by the MOS The length of time spent in AIT depends on the MOS of the soldier, and some highly technical MOS training may require many months (e.g., foreign language translators). Depending on the needs of the army, Basic Combat Training for combat arms soldiers is conducted at a number of locations, but two of the longest-running are the Armor School and the Infantry School, both at Fort Benning, Georgia.
How long does basic training last?
A: 10 weeks


Context and question: The immediate predecessors of MP3 were "Optimum Coding in the Frequency Domain" (OCF), and Perceptual Transform Coding (PXFM). These two codecs, along with block-switching contributions from Thomson-Brandt, were merged into a codec called ASPEC, which was submitted to MPEG, and which won the quality competition, but that was mistakenly rejected as too complex to implement. The first practical implementation of an audio perceptual coder (OCF) in hardware (Krasner's hardware was too cumbersome and slow for practical use), was an implementation of a psychoacoustic transform coder based on Motorola 56000 DSP chips.
What does OCF stand for?
Answer: Optimum Coding in the Frequency Domain


Question: Palermo (Italian: [paˈlɛrmo] ( listen), Sicilian: Palermu, Latin: Panormus, from Greek: Πάνορμος, Panormos, Arabic: بَلَرْم‎, Balarm; Phoenician: זִיז, Ziz) is a city in Insular Italy, the capital of both the autonomous region of Sicily and the Province of Palermo. The city is noted for its history, culture, architecture and gastronomy, playing an important role throughout much of its existence; it is over 2,700 years old. Palermo is located in the northwest of the island of Sicily, right by the Gulf of Palermo in the Tyrrhenian Sea.
Is there an answer to this question: What city is near the Tyrrhenian Gulf?

Answer: unanswerable


Physiologically, the function of the brain is to exert centralized control over the other organs of the body. The brain acts on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Reflexes only require one of what two structures in a body?
Ah, so..
spinal cord or peripheral ganglia
