Background: Medical researcher: As expected, records covering
the last four years of ten major hospitals
indicate that babies born prematurely were
more likely to have low birth weights and to
suffer from health problems than were babies
not born prematurely.
Premise: These records also
indicate that mothers who had received
adequate prenatal care were less likely to have
low birth weight babies than were mothers who
had received inadequate prenatal care.
Conclusion: Adequate prenatal care, therefore, significantly
decreases the risk of low birth weight babies.

secure in order to compete for depositors' money.
