Ashley and Jessica, sisters born two years apart, grew up in an impoverished, violent neighborhood. As adults, Ashley is chronically jobless and is addicted to drugs while Jessica is a professor of economics at a community college. What might explain their different life outcomes?

Based on the information provided within the question it can be said that the theory that would best explain the different life outcomes would be genetic differential sensitivity theory. This theory basically poses that individuals that have a specific genetic makeup become more susceptible towards bad influences in the surroundings in which they grow up as opposed to people without those genetic makeups. Which would explain why Ashley is addicted to drugs but Jessica is a professor even though they both grew up in the same environment.
