问题     It is hard to imagine life without Arabic numbers(数字). No other number systerm ever invented has a simple way to write a number like 1984. In Roman numeral, it comes out like this MCMLXXXIV. Imagine how difficult it would be for a school pupil to remember it!
    The Arabs, however, call their numbers "Indian numerals". This is probably because they got the original idea a long time ago from India. There were no printed newspapers or scientific magazines then, so mathematics traveled along the same routes that silk did, as businessmen so and bought goods. The Arabs took the new numbers and made improvements that guickly led to advances in technology.
    The achievements of Arabic technology can be seen from a passage in a 10th-century boo about an Arabic city:"The neighboring country showed the results of careful work in agriculture, trade, and industry, Rice and many other plants were grown in fields with water supplied by Arab engineers. The city included 900 public baths, stone-covered streets, fountains, and beautiful buildings. " At this time, London was a small town with dirty streets, and Berlin was a farming village. In fact, cities outside the Arab world did not reach the same level of social development until centuries later.
This passage tells us that the Arabs were a people______.

选项 A、inventing Roman numerals
B、having advanced technology long ago
C、growing corn and many other plant then
D、supplying other countries with colorful silk

答案B
