Question

source b: the casta system painting commissioned by the spanish crown + secondary source description)
context: this text describes the casta system and the paintings that
represented it in the 18th century.

the casta system was a social and racial hierarchy used by the spanish
elite to classify the mixed - race population. a persons casta (lineage)
determined their social status, legal rights, and economic opportunities.
this system was visualized in casta paintings. these were sets of 16
portraits that showed a man and woman of different races... and the child
they produced, who was given a new casta label... the paintings
attempted to show a \scientific\ explanation for classifying white
spaniards at the top and african slaves at the bottom.

who is the author?	what rhetorical strategy are they using? how do you know (use evidence from the text)?(ethos, pathos, logos)	why are they using this rhetorical strategy? (in other words, what is their main goal?)

Explanation:

The casta system was a social hierarchy to justify Spanish elite's control. Using logos (scientific - like classification) and the paintings, the Spanish Crown aimed to legitimize the racial hierarchy, enforce social order, and maintain their power by making the system seem rational, ensuring white Spaniards' dominance and controlling mixed - race and enslaved populations.

Answer:

The Spanish Crown (and the secondary source author) uses this rhetorical strategy (Logos) to legitimize the casta system, enforce social hierarchy, maintain white Spanish dominance, and control the mixed - race and enslaved populations by presenting the racial classification as a "scientific" and rational order.
