Final answer:
The introduction of a cash economy, advancements in technology, and improvements in transportation and communication made it easier to exchange goods during this time.
Step-by-step explanation:
The new development that made it easier to exchange goods during this time was the introduction of a cash economy. Money became a medium for the exchange of goods and services among individuals and groups. It took various forms such as sea shells, coins, and paper notes. The use of money greatly facilitated trade and made it more efficient.
The combination of readily available mass-produced goods, running water, and gas and electricity also improved the exchange of goods. These advancements made goods more accessible and increased the efficiency of production and distribution.
Additionally, advances in transportation and communication technologies reduced the costs of moving goods around the globe. The development of containerization in shipping drastically reduced the cost of moving goods, and communication technologies like telegraphs and telephones improved information flow internationally.
