Read the passage, then choose the correct answer to each of the questions that follow.
 
In ancient times wealth was measured and exchanged tangibly, in things that could be touched: food, tools, and precious metals and stones. Then barter system was replaced by coins, which still had real value since they were pieces of rare metal. Coins were followed by flat money, paper notes that have value only because everyone agrees to accept them.
Today electronic monetary systems are gradually being introduced that will transform money into even less tangible  forms,  reducing it  to  arrays  of „bits  and  bytes‟ or  units  of computerized information, whizzing between machines at the speed of light. Already, electronic fund transfer allows money to be instantly sent and received by different banks, companies, and countries through computers and telecommunication devices.
