Final answer:
The social factor that could influence aggressive young adults' reluctance towards education is their family background, as it shapes their socio-economic environment and directly impacts their educational opportunities and challenges.
Step-by-step explanation:
When considering the social factors that could influence aggressive young adults' reluctance toward education, family background stands out as a critical element. As illustrated by the concept that one's socio-economic environment shapes educational opportunities, students from lower socio-economic backgrounds may face challenges such as needing to contribute to the family's income, lack of study support at home, and limited access to technology. These circumstances make it difficult for them to prioritize and excel in education. Hence, in the context of the question, 'Aggressive young adults, who had fewer friends than temperate peers, rated themselves as quite conscientious and had high arrest records. What social factor could influence their reluctance toward education?', family background significantly impacts these individuals' educational outcomes and their capacity to engage with schooling effectively.
