Final answer:
I would focus on secondary sources, such as a meta-analysis, to repeat the study on the link between Alzheimer's and diet conducted by Scottish researchers.
Step-by-step explanation:
If I were part of a team at a university that wanted to repeat the study on the link between Alzheimer's and diet conducted by Scottish researchers, I would focus on secondary sources. This is because secondary data, such as previously published studies and statistics, can provide valuable insights and save time and resources compared to collecting primary data. One suitable secondary source that I would choose is a meta-analysis of various studies on Alzheimer's and diet. A meta-analysis combines the findings from multiple studies to provide a comprehensive overview of the topic, allowing for a more reliable assessment of the relationship between diet and Alzheimer's.
