Question

four students do research on the impact of sugar on developing heart disease and present arguments based upon their research as seen on this chart.

student	source	conclusion
student 2	journal article	the journal presented summaries of how studies on the impact of sugar on heart disease have changed over the years.
student 3	youtube	the video showed how many packets are in a single can of soda.
student 4	research presentation	the presentation summarized a study in which researchers found that people with heart disease ate more sugar, on average, than people without heart disease.

whose research reached a conclusion supported by empirical evidence and scientific reasoning?
a student 1
b student 2
c student 3
d student 4

Explanation:

To determine which research is supported by empirical evidence and scientific reasoning, we analyze each student:

• Student 1: Used a blog (non - peer - reviewed, opinion - based) to discuss sugar alternatives, lacking empirical/scientific support.
• Student 2: Used a journal article (peer - reviewed, scientific) to summarize studies on sugar's impact on heart disease over time, which involves scientific reasoning and empirical evidence from studies.
• Student 3: Used YouTube (non - scientific, potentially anecdotal) to show soda sugar content, not empirical/scientific research on heart disease.
• Student 4: Used a research presentation, but the conclusion is a summary of a study without clear indication of empirical evidence and scientific reasoning as strong as a journal article. Journal articles are more likely to have empirical evidence (data from studies) and scientific reasoning (analysis of that data).

Answer:

B. Student 2
