Explanation:

To design an investigation on how omega - 3 supplements affect mental health, first, define the target population (e.g., age - range, pre - existing mental health conditions). Then, create two groups: a treatment group receiving omega - 3 supplements and a control group receiving a placebo. Use standardized mental health questionnaires (e.g., Beck Depression Inventory) at the start and end of the study period to measure changes. Regarding the article, look for details on previous research findings, dosage recommendations, and potential confounding factors to refine the scientific question. For example, if the article shows that omega - 3 affects different genders differently, the scientific question could be refined to "How do omega - 3 supplements affect mental health in men and women differently?"

Answer:

To design the investigation: Define population, create treatment and control groups, use standardized questionnaires. To refine the scientific question from the article: Look for previous findings, dosage info, and confounding factors.
