Why does English often serve as a lingua franca throughout South and Southeast Asia?

Answer:

Responses may vary but should include some or all of the following information: Many countries in this region have great language diversity. For example, India has 22 official languages, and more than 400 languages are spoken. This means it can be very difficult to communicate for purposes of education, science, or trade. As a result, a lingua franca, or a common language, often serves as way for people to communicate. Because of the heritage of British colonialism in the region, as well as the dominance of the US economy in recent years, English is often the most convenient language for many to use.
