Final answer:
The most complete question related to intelligence and early literacy is option (C), which asks about the relationship between intelligence and literacy at a young age without presupposing causation or direct correlation.
Step-by-step explanation:
The most complete question for the phrase "Intelligent - she is literate at a young age" is (C) What is the relationship between intelligence and literacy at a young age? This question is the most comprehensive as it does not assume one causes the other or that they are necessarily directly related; rather, it allows for exploration of the possibility of a correlation, causation, or simply an association between two factors. This open-ended question also encompasses potential environmental, genetic, and social factors that could influence the development of intelligence and literacy skills at a young age.
It is important to understand that intelligence is a complex trait influenced by a variety of factors, which can include genetics, the environment in which an individual is raised, and their early experiences with language and learning. Evidence suggests that rich stimulation in the early years can benefit intelligence levels, and conversely, certain learning disabilities can impact a child's ability to read and write without necessarily reflecting on their overall intelligence. Examining the factors contributing to adult literacy, as well as considering the manifest functions of schools, such as learning to read and write, are all relevant to this discussion.
