Final answer:
The best example of cultural convergence is option (B), where different countries in Europe have similar standards of living and systems of government, as this represents cultures adopting similar traits.
Step-by-step explanation:
The best example of cultural convergence among the options provided is (B) Different countries in Europe today have similar standards of living and systems of government. This option reflects the phenomenon where different cultures come together and adopt similar traits, such as democratic ideas, technological advancements, language, and governmental systems. Cultural convergence might be observed in the widespread use of US-based fast-food franchises, the adoption of the English language, or the global reach of sports and entertainment.
Examples such as Turkish "guest workers" in Germany not being able to read or write German (A), people in the Sahel region of Africa moving because of drought (C), and universities not requiring foreign language studies (D), do not represent cultural convergence, but rather individual situations that do not necessarily involve the blending of cultural aspects.
