I want to know the answer to the following question:
Which boroughs was the Mexico City borough split into?
All the background I'm provided with is that "In 1970 Mexico City was split into four different delegaciones: Cuauhtémoc, Miguel Hidalgo, Venustiano Carranza and Benito Juárez, increasing the number of delegaciones to sixteen.". Is that enough to answer the question?
Answer: yes
