Answer:
The research is not COMPLEX
The most effective revision would be "How did Parks establish himself as a successful photographer?"
Step-by-step explanation:
The initial research question is less effective because it is not complex. It has a simple one-word answer: a single year. Given that this is the issue with the inquiry, the most effective revision would be a question about Parks’s early photography career. It is related to the idea of Parks purchasing his first camera, but it has a much more complex answer that merits a research project. The question about Parks’s photography equipment is not concise, the question about who sold Parks his first camera is not complex, and the question about why pawnshops are important to photographers is not focused because it is too broad.
