Multiple Choice

Choose the appropriate letter to identify the main idea implied by the paragraph. The first study of very-low-birth-weight children (those who weigh less than three pounds four ounces at birth) was completed in 2001.A group of researchers led by Dr.Maureen Hack followed for two decades 242 very-low-birth-weight babies born in Cleveland between 1977 and 1979.When the subjects reached age twenty, the researchers compared them to a control group of 233 normal-birth-weight children born in the same city during the same time frame.As the researchers had predicted, the low-birth-weight group was much more likely than the control group to suffer from chronic medical ailments.These conditions included cerebral palsy, blindness, deafness, and lung disease, many of them arising from complications at birth.
