QUES: The code itself was patterned so that most control codes were together, and all graphic codes were together, for ease of identification. The first two columns (32 positions) were reserved for control characters.:220, 2368,9) The "space" character had to come before graphics to make sorting easier, so it became position 20hex;:23710 for the same reason, many special signs commonly used as separators were placed before digits. The committee decided it was important to support uppercase 64-character alphabets, and chose to pattern ASCII so it could be reduced easily to a usable 64-character set of graphic codes,:228, 23714 as was done in the DEC SIXBIT code. Lowercase letters were therefore not interleaved with uppercase. To keep options available for lowercase letters and other graphics, the special and numeric codes were arranged before the letters, and the letter A was placed in position 41hex to match the draft of the corresponding British standard.:23818 The digits 09 were arranged so they correspond to values in binary prefixed with 011, making conversion with binary-coded decimal straightforward.

QUES: Slavery and slaves were part of the social order; there were slave markets where they could be bought and sold. Many slaves were freed by the masters for services rendered; some slaves could save money to buy their freedom. Generally, mutilation and murder of slaves was prohibited by legislation. However, Rome did not have a law enforcement arm. All actions were treated as "torts," which were brought by an accuser who was forced to prove the entire case himself. If the accused were a noble and the victim, not a noble, the likelihood of finding for the accused was small. At most, the accused might have to pay a fine for killing a slave. It is estimated that over 25% of the Roman population was enslaved.

What branch of law did Rome lack?
What is the answer?
ANS: law enforcement
QUES: While on one hand the Heian period was an unusually long period of peace, it can also be argued that the period weakened Japan economically and led to poverty for all but a tiny few of its inhabitants. The control of rice fields provided a key source of income for families such as the Fujiwara and were a fundamental base for their power. The aristocratic beneficiaries of Heian culture, the Ryomin ( "Good People") numbered about five thousand in a land of perhaps five million. One reason the samurai were able to take power was that the ruling nobility proved incompetent at managing Japan and its provinces. By the year 1000 the government no longer knew how to issue currency and money was gradually disappearing. Instead of a fully realised system of money circulation, rice was the primary unit of exchange. The lack of a solid medium of economic exchange is implicitly illustrated in novels of the time. For instance, messengers were rewarded with useful objects, e.g., an old silk kimono, rather than paid a fee.

Currency gradually disappeared around what year?
