Answer:
The central idea of the Seven Voyages of Sinbad is that Sinbad is a brave and adventurous sailor who seeks wealth and fame through his travels, but also faces many dangers and challenges along the way. One text that best supports this central idea is from the first voyage, where Sinbad says:
Do not imagine that I am unjust, or take me for a robber. I am no more than one of those merchants who trade in different countries, and who have come to Ballab to sell or buy what we can. The law among merchants is to buy for money, or exchange goods, but never to take things by force. It is therefore only just that you should let me have part of your treasure.
This text shows that Sinbad is not a violent or greedy person, but rather a fair and honest trader who respects the law and the customs of other lands. He also reveals his motivation for sailing across the seas: to trade and make profit. However, he also acknowledges the risks and hardships that he has to endure, such as being shipwrecked on an island that turns out to be a whale, or being captured by a giant bird. These experiences demonstrate his courage and resilience in the face of adversity, as well as his curiosity and wonder for the unknown. Therefore, this text supports the central idea of Sinbad’s character and adventures.
