Paragraph Test - Twelve

Answer the questions according to the reading passages.
A simple method of central heating has long been in use in northern China. A raised floor space for sleeping is built over the area where the fire or oven is situated. This primitive central heating has been known since Han Dynasty times (202 B.C -A.D220). Similar forms of underfloor heating in the West may have inspired the breakthrough achieved by Sergius Orate, a Roman businessman who lived about 100 B.C. Orate was a fish and oyster farmer and to keep his stock healthy, he invented a way of keeping warm the large tanks in which they were kept. This involved raising the floor of the tanks of stock on tiles like short pillars. A nearby furnace produced hot air, which passed underneath the tanks and kept the water at a steady temperature.
