• A) Although important,stress hormones were not as predictive of relationship status and quality 10 years later as were the negative behaviors partners displayed during these discussions.
• B) Stress hormones were far more predictive of relationship status and quality 10 years later compared to the negative behaviors partners displayed during these discussions.
• C) Observable features of conflict (e.g. ,negative statements,criticism)revealed all of the clues needed for predicting the status and quality of the relationship 10 years later.
