Most famous medieval cathedrals are in Europe (where the Christians were), and they were built between about 1000 and 1600 AD, during the Middle Ages. There are cathedrals all over Europe, in Spain, in England, in France, in Germany, and in Italy. The architecture of cathedrals is based on the old Roman basilica.

and then asked what the distance is between points C and D. Since C and D are on the same line, all you have to do is count the spots from C to D. The answer is 2 units. Same thing goes if you were asked for the difference between B and D, since they are also both on the same line.
