Rationale: In an experimental study, the independent variable is the factor being manipulated or controlled by the researcher. In this case, the frequency of read-alouds is the variable that researchers would intentionally change or vary to see its effect on the dependent variable, which is the children's vocabulary scores. The other options (B. type of books parents read, C. child's vocabulary score, and D. difficulty of vocabulary words) are not the independent variable in this study as they are either irrelevant or are the outcome being measured.

Correct Answer: B

Rationale: Babies who are both preterm and economically disadvantaged typically require long-term, intensive intervention. This is because the combination of being born preterm and being economically disadvantaged can pose significant challenges for the infant's development. Providing ongoing support and interventions can help address these challenges and promote healthy development in these infants.

Correct Answer: D
