Question: ASCII (i/ˈæski/ ASS-kee), abbreviated from American Standard Code for Information Interchange, is a character-encoding scheme (the IANA prefers the name US-ASCII). ASCII codes represent text in computers, communications equipment, and other devices that use text. Most modern character-encoding schemes are based on ASCII, though they support many additional characters. ASCII was the most common character encoding on the World Wide Web until December 2007, when it was surpassed by UTF-8, which is fully backward compatibe to ASCII.
Is there an answer to this question: Who made ASCII obselete?

Answer: unanswerable


Question: The evolution of the Greek economy during the 19th century (a period that transformed a large part of the world because of the Industrial Revolution) has been little researched. Recent research from 2006 examines the gradual development of industry and further development of shipping in a predominantly agricultural economy, calculating an average rate of per capita GDP growth between 1833 and 1911 that was only slightly lower than that of the other Western European nations. Industrial activity, (including heavy industry like shipbuilding) was evident, mainly in Ermoupolis and Piraeus. Nonetheless, Greece faced economic hardships and defaulted on its external loans in 1826, 1843, 1860 and 1894.
Is there an answer to this question: What type of industrial activity was evident in Greece in the period researched?

Answer: shipbuilding


Question: Hellenistic military equipment was generally characterized by an increase in size. Hellenistic-era warships grew from the trireme to include more banks of oars and larger numbers of rowers and soldiers as in the Quadrireme and Quinquereme. The Ptolemaic Tessarakonteres was the largest ship constructed in Antiquity. New siege engines were developed during this period. An unknown engineer developed the torsion-spring catapult (ca. 360) and Dionysios of Alexandria designed a repeating ballista, the Polybolos. Preserved examples of ball projectiles range from 4.4 kg to 78 kg (or over 170 lbs). Demetrius Poliorcetes was notorious for the large siege engines employed in his campaigns, especially during the 12-month siege of Rhodes when he had Epimachos of Athens build a massive 160 ton siege tower named Helepolis, filled with artillery.
Is there an answer to this question: What type of weapon is the Polybolos?

Answer: ballista


Question: Since the system's launch, production costs have been reduced significantly as a result of phasing out the Emotion Engine chip and falling hardware costs. The cost of manufacturing Cell microprocessors has fallen dramatically as a result of moving to the 65 nm production process, and Blu-ray Disc diodes have become cheaper to manufacture. As of January 2008, each unit cost around $400 to manufacture; by August 2009, Sony had reduced costs by a total of 70%, meaning it only costs Sony around $240 per unit.
Is there an answer to this question: As of Summer 2009, what was the cost to Sony to make a PS3?

Answer:
$240
