Passage Summary: While it's true that kids with divorced parents have more mental health struggles, a researcher argues this isn't due to the divorce. Instead, the same toxic habits that broke up the marriage are taught to the kids, causing their problems.

Conclusion: The psychological issues seen in children of divorced parents are likely caused by behaviors learned from parents rather than the divorce itself.

Reasoning: Behaviors like hostility and distrust both increase the chance of divorce and are passed to children, leading to their psychological struggles.

Analysis: The statement in question serves as an introductory premise that establishes a correlation the researcher intends to explain. By acknowledging this higher rate of psychological problems first, the author sets the stage to challenge a common interpretation of that fact. I identified this role because the rest of the argument is dedicated to providing an alternative cause for this specific observation. In the world of social science, it's a classic move to take a known statistic and argue that everyone has been blaming the wrong culprit.
