Final answer:
Bernadette's research plan could be improved by focusing on her research question and adjusting its scope to be more manageable yet comprehensive, leading to a more effective presentation of her findings.
Therefore, option C is correct answer.
Step-by-step explanation:
Bernadette's research plan needs to be improved. One potential area that might need enhancement is the research question. It is vital to ensure that the research question is focused, clear, and manageable. A broad or vague question can lead to difficulties in conducting the research and presenting findings. She can improve her research plan by broadening her research question if it is too narrow, or narrowing it down if it's too broad, ensuring that it is specific enough to be answerable within the scope of her project yet broad enough to provide substantive information that contributes to her field of study. This approach will help in generating a more effective presentation as it gives a clear direction to the research, helping to guide the gathering and analysis of data.
