Excerpt:

Many marketable commodities are produced here. And many ships come here laden with cloth of gold and various silken fabrics, and much else besides that I will not attempt to specify, and exchange them for local products. They arrive and depart with full cargoes and the merchants make a handsome profit on the transaction.

To illustrate the wealth and commercial success of the

region

Explanation:

This is an excerpt from chapter 8 of ''The Travels of Marco Polo'' and it is illustrating one of his adventures or travels. In this excerpt we can see how good commercial success was back then and he is describing all of it when he is talking about gold, various silken fabrics, many ships.

We must consider the time when he was traveling because it wasn't able for everyone to travel and he was doing it all the time so he was informed by everything in other locations. That is also the reason why this excerpt is illustrating the wealth too.
