答案解析

A。本题考查对文章多处重要细节的推断。根据题干信息词geographical focal point将答案定位到文章第三段第一、二句。文中提到，每个中世纪城市开始时只是一个小定居地，它们围绕着地理或文化的焦点而成长起来，这类焦点往往是一幢永久性的建筑物，比如堡垒、大教堂或是大礼堂，倒数第三句也提到，对城市地理研究发现，一个城镇的其他最古老的部分也被认为是核心定居地，结合选项可知本题选A。

1 根据以下资料,回答题:
        Most earthquakes occur within the upper 15 miles of the earth's surface．But earthquakes can and do occur at all depths to about 460 miles．Their number decreases as the depth increases．At about 460 miles one earthquake occurs only every few years．Near the surface earthquakes may run as high as 100,in a month, but the yearly average does not vary much．In comparison with the total number of earthquakes each year, the number of disastrous earthquakes is very small．
        The extent of the disaster in an earthquake depends on many factors．If you carefully build a toy house with an erect set, it will still stand no matter how much you shake the table．But if you build a toy house with a pack of cards, a slight shake of the table will make it fall．An earthquake in Agadir, Morocco, was not Strong enough to be recorded on distant instruments, but it completely destroyed the city．Many stronger earthquakes have done comparatively little damage．If a building is well constructed and built on solid ground, it will resist an earthquake．
Most deaths in earthquakes have been due to faulty building construction or poor building sites．A third and very serious factor is panic．When people rush out into narrow streets, more deaths will result．
        The Unted Nations has played an important part in reducing the damage done by earthquakes．It has sent a team of experts to all countries known to be affected by earthquakes．Working with local geologists and engineers,the experts have studied the nature of the ground and the type of most practical building code for the local area．If followed, these suggestions will make disastrous earthquakes almost a thing of the past．
        There is one type of earthquake disaster that little can be done about．This is the disaster caused by seismic sea waves, or tsunamis．(These are often called tidal waves, but the name is incorrect．They have nothing to do with　tides．) In cectain areas, earthquakes take place beneath the sea．These submarine earthquakes sometimes give rise　to seismic sea waves．The waves are not noticeable out at sea because of their long wave length．But when they roll　into harbors they pile up into walls of water 6 to 60 feet high．The Japanese call them "tsunamis", meaning　"harbor waves", because they reach a sizable height only in harbors．
        Tsunamis travel fairly slowly, at speeds up to 500 miles an hour．An adequate warning system is in use to warn　all shores likely to be reached by the waves．But this only enables people to leave the threatened shores for higher　ground．There is no way to stop the oncoming wave．
