Final answer:
The idea that Lucas Siqueira may not get a government position due to not being identified as Prado (brown) is considered a public/social issue, relating to societal discrimination based on race/color and historical struggles of mixed-race individuals referenced in historical literature.
Step-by-step explanation:
The situation described regarding Lucas Siqueira not being identified as Prado (brown) and the potential impact this may have on his ability to gain a government position can be considered a public/social issue. It is a reflection of broader societal structures and discrimination based on race and color that may affect individuals' access to opportunities and rights. It relates to the historical context of mixed-race individuals and their struggle for social mobility and acceptance, referenced in Alejandro E. Gómez's article discussing the political struggles of free coloreds during the Caracas Revolution. The article highlights the reaction of the colonial elite to the upward social mobility of mixed-race people, portraying the resistance and prejudice they faced. The concept of scapegoating, as described in one of the provided passages, can be understood in this scenario as part of the explanation of how these racial dynamics play out in societies. Scapegoat theory suggests that dominant groups may blame subordinate groups for problems, reflecting the prejudices and social constructs that underpin social and racial hierarchies.
