Question

The passage most strongly suggests that prior to the research initiatives described in lines 42-53

• A. Little research had been conducted on the causes of newborn mortality.
• B. Influenza research had yielded the most effective treatments.
• C. A treatment for PKU was implemented, despite its inherent risks.
• D. Screening newborns for genetic diseases was a well-established practice.

Answer 1

The correct option is A Little research had been conducted on the causes of newborn mortality.

Prior to the research initiatives taken in lines 42-53, only the most prominent causes of infant mortality like infectious diseases were focused upon. Genetic discrepancies were overlooked. Hence, the little research and option A is correct. The rest of the options do not express this meaning, hence, incorrect.
