I want to know the answer to the following question:
Are Arizona and New Mexico residents speaking Spanish or English?
All the background I'm provided with is that "The area of the former Gadsden Purchase contained a majority of Spanish-speakers until the 1940s, although the Tucson area had a higher ratio of anglophones (including Mexican Americans who were fluent in English); the continuous arrival of Mexican settlers increases the number of Spanish-speakers.". Is that enough to answer the question?
Answer: yes
