Step-by-step explanation:
The theme in this excerpt from The Little Prince by Antoine de Saint-Exupéry is "the mistrust among strangers." The passage highlights how the Turkish astronomer's discovery was not believed by the International Astronomical Congress because he was dressed in Turkish costume, showing how grown-ups can be dismissive and judgmental of unfamiliar cultures and appearances. However, when the astronomer dressed in European style, his report was accepted, demonstrating how appearances can influence trust and acceptance. The theme of mistrust among strangers is further emphasized by the fact that the Turkish dictator had to make a law to force his subjects to change their costumes, indicating resistance to change and mistrust of foreign cultures.
