Answer:
I believe that teaching is better in the country's native language.
Explanation:
It is better in the country's native language because that country will most likely have a higher percentage of native speakers there. Such as the United States. They have a higher percentage of American English Speakers. It may sound wrong but if a person comes to a certain country and go to school there, they should learn that country's language and learn in that language. Though, English is the highest language used in the entire world. I think it's better to teach in the country's native language.
