Final answer:
The conflict between Rebecca Nurse and Ann Putnam arises from Ann's envy and grief over Rebecca's large family and her own tragic losses of seven babies, which fosters resentment.
Step-by-step explanation:
The source of conflict between Rebecca Nurse and Ann Putnam stems from deep-seated grief and envy due to contrasting maternal experiences. Rebecca Nurse has been blessed with a large, thriving family, having 11 children and 26 grandchildren, while Ann Putnam has faced the tragic loss of seven babies.
This stark difference in their lives has sown the seeds of resentment, leading Ann Putnam to harbor feelings of jealousy and bitterness towards Rebecca.
