I want to know the answer to the following question:
In which city did Obregon sign a number of treaties?
All the background I'm provided with is that "The fight against Huerta formally ended on August 15, 1914, when Álvaro Obregón signed a number of treaties in Teoloyucan in which the last of Huerta's forces surrendered to him and recognized the constitutional government.". Is that enough to answer the question?
Answer: yes
