Which of these statements reflects a negative view of New Mexico during the 19th century?

The statement that New Mexico was dirtier than major cities provides a negative perspective on the region during the 19th century. This reflects a criticism of the sanitation and living conditions in New Mexico at that time, implying that it lagged behind more developed urban areas. It suggests a lack of proper public health measures and could indicate issues like poverty or inadequate governance at the time.

In contrast, the other statements describe positive attributes of the region. For instance, stating that New Mexico was prosperous and well-governed indicates a thriving community with effective leadership. Highlighting excellent infrastructure points to advancements in roads, transportation, and public services that contribute positively to daily life and economic growth. Claiming a thriving economy reflects a robust market and trade situation that would be seen as encouraging and beneficial. All of these factors contribute positively to the image of New Mexico, making the mentioned statement a notable departure from that trend.
