Summative assessment for the third term Reading . Read the text and answer the following questions : Treasure Hunting If you dream of adventures , you probably picture to yourself desert islands , wrecks of sunken ships and old chests filled with jewellery and coins . For some people these dreams have come true . It is because they really know where to look for treasure . One of the best places for treasure hunting is the Atlantic Ocean near the eastern coast of Florida . This place is called " Treasure Coast " . Between the 16th and 18th century many Spanish ships sank near the coast and their wrecks were buried in the sand among the coral reefs . These ships sailed from Mexico to Spain and carried gold , silver and precious stones . They also transported Spanish soldiers and governors who were coming back home from the colonies with their own gold . Most ships sank not very far from the coast . There was only one narrow channel , which ran between the massive and dangerous coral reefs . Besides , tropical storms or hurricanes were very common in late summer or early autumn and the ships often broke into pieces . The exploration of the sea near the coast has begun in the twentieth century when records of shipwrecks were found in the Spanish archives . First , there came scuba divers with metal detectors . Then , with the discovery of the first Spanish ship in the early 1970s , many people started treasure hunting . They were looking for anchors , captains ' diaries and obviously for gold , silver and coins . Today , the treasure hunting is an expensive game , which requires professional equipment and expert divers . It is exhausting and quite dangerous . It takes divers long hours to search for a ship under water but if they are lucky , they feel excited . 1. What is the best place for treasure according to the text ? 2.
