A researcher collects information regarding the relationship of drinking orange juice and preventing the common cold. Which method would best assist the researcher in reaching a conclusion?
Conduct a survey of those who drink orange juice to prevent a cold.
Review the chemical composition of orange juice.
Drink orange juice when a cold is coming on.
Analyze the research data found in the scientific journals.
The Correct Answer is D
A. Conduct a survey of those who drink orange juice to prevent a cold: While a survey might provide some data on people's behaviors, it wouldn't establish a cause-and-effect relationship between drinking orange juice and preventing the common cold. Surveys can show trends, but they can't confirm scientific conclusions without controlled experimental data.
B. Review the chemical composition of orange juice: Understanding the composition of orange juice (such as its vitamin C content) is important, but it doesn't directly address whether it prevents colds. The researcher needs to look at studies that investigate the outcome of drinking orange juice, not just its ingredients.
C. Drink orange juice when a cold is coming on: This is more of a personal action than a scientific approach. The researcher would need to gather evidence from controlled studies rather than relying on personal experience or anecdotal evidence.
D. Analyze the research data found in the scientific journals: This is the best method. Reviewing existing scientific studies allows the researcher to see what previous research has found about the relationship between orange juice and cold prevention. Published studies typically include controlled experiments, systematic reviews, and meta-analyses that provide reliable evidence and conclusions.

Correct Answer is A
Explanation
A. Making an informed decision requires critical thinking and weighing the pros and cons of each possible solution. This approach helps consumers evaluate credibility, feasibility, and personal impact.
B. Determining why people have so many opinions may be interesting but does not directly help in making an informed decision.
C. Realizing that it is impossible to sort through so many viewpoints reflects a defeatist attitude and discourages critical thinking, which is essential in informed decision-making.
D. Interviewing each person who has a different viewpoint is impractical and unnecessary. A consumer can access and evaluate different perspectives through research and credible sources without personally interviewing everyone.
Correct Answer is B
Explanation
A. The man complains frequently and counseling is recommended: This option implies that the man’s symptoms may be psychological, but it does not provide the best explanation for the situation. Even though his test results are normal, there could still be an underlying physical issue or condition that has not yet been identified. Counseling might be helpful, but it's not the best explanation based on the information given.
B. Even though the tests are normal, continual monitoring is needed: This is the most appropriate answer. Normal test results mean no immediate, obvious cause has been found for the symptoms. However, symptoms like headaches and visual disturbances could be early indicators of a condition that has not yet been detected, so continued monitoring might be necessary to track any changes over time.
C. The signs and symptoms reported by the man are not real: This option is dismissive and not a reasonable conclusion. Just because the tests are normal doesn’t mean the symptoms aren’t real. The man’s experience of headaches and visual disturbances is valid, even if a physical cause hasn't been found yet.
D. The man has many physical problems that cannot be explained: While this might be a possibility, it’s a broader and less specific explanation. The fact that tests are normal means there isn’t currently evidence of a serious physical issue that is identifiable. It's more reasonable to focus on monitoring and further investigation if needed.
