Final answer:
Possible reasons for preterm delivery can include Preterm premature rupture of membranes (PPROM), infection, and lifestyle factors such as smoking. Complications may require a Caesarean section to ensure safe delivery.
Step-by-step explanation:
Tamara delivered her babies preterm due to possible reasons such as Preterm premature rupture of membranes (PPROM), which is a condition where the amniotic sac leaks fluid before 38 weeks of gestation. PPROM can result from a bacterial infection, structural defects in the amniotic sac, uterus, or cervix. Other possible causes of preterm delivery can include maternal factors such as infections like vaginitis, lifestyle factors like smoking, or health complications that necessitate a Caesarean section for the safe delivery of the baby.
