A Researcher Includes the Following Problem Statement in a Research

A researcher includes the following problem statement in a research proposal: "Children in publicly funded school breakfast programs often have learning delays. These are not readily attributable to single causes. Research on learning delays has revealed that family literacy, measured by parental reading level and comprehension scores, is the most powerful predictor of delay in the primary grades. On the other hand, repeated exposure to eyes-on reading, in the company of a trusted nonparent adult or peer, has been shown to override family literacy as a predictor. No research, however, has studied institution of a reading-and-breakfast program, delivered 5 days a week before school, intended to override the variable of family literacy." Given this problem statement, which of these purposes would be appropriate for the study?

A) The purpose of the study is to determine whether providing volunteer readers during school breakfasts for all kindergarten and first-grade children will result in fewer than anticipated learning delays.
B) The purpose of the study is to determine the lived experience of children with learning delays, against the context of school and home, and to examine the children's peer relationships.
C) The purpose of the study is to determine whether a buddy system of one sixth-grader, and one kindergartner or first-grader, who eat breakfast together and then read together for 20 minutes, is effective in decreasing the anticipated number learning delays.
D) The purpose of the study is to experimentally determine what causes learning delays, by introducing various strategies already in place in community primary schools and measuring their effect, using basic research.
E) The purpose of the study is to measure the effectiveness of using school computers, allowing children to visually scan a story concurrently read by a schoolteacher over the cafeteria microphone during school breakfast time, in decreasing the incidence and severity of learning delays.
