Final answer:
Santiago's view that the social environment determines the range of teenage experiences is most closely aligned with the perspective of anthropologist Margaret Mead. The correct option is 3.
Step-by-step explanation:
Santiago's view that the social environment is entirely responsible for the range of teenage experiences aligns most closely with the perspective of Margaret Mead. Mead's anthropological research suggested that the turbulence of adolescence is not a natural and unavoidable phase, but rather a byproduct of cultural influences and environmental factors.
Contrary to G. Stanley Hall's notion of adolescence as a period of 'storm and stress', Mead emphasized the role of societal structures and expectations in shaping the adolescent experience. This viewpoint aligns with Santiago's perspective on the role of the social environment in determining teenage behavior.
