The highly dispersed nature of Panzaleo pottery throughout present-day Ecuador has led archaeologists to speculate about the pottery's origins and significance. Jijon y Caamano attributed the pottery's distribution to trade, and based on the large quantities of pottery recovered in the Ambato-Latacunga region of the central Ecuadorian highlands, he proposed that region as the probable locus of production. However. Porras suggests that inhabitants of the subtropical eastern Andean slopes, or montaria. were the original producers of Panzaleo. Ponas" theory involves the forced migration of the montaria population from then homeland in the Quijos River valley into the Ecuadorian highlands. The gradual exodus and ensuing dispersal of the makers of this ware could account for the diffuse distribution of the materials.

It can be inferred from the passage that Jijon y Caamano would probably agree with which of the following statements about the distribution of Panzaleo pottery throughout Ecuador?
