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 C
Explanation
A. 1, 4, 5, 6, 7: Classroom 1 is selected, which means no one from class 5 can be selected, but class 5 is selected in this option. This violates the first condition.
B. 1, 2, 3, 4, 5: Classroom 1 is selected, so no one from class 5 should be chosen, but class 5 is selected. This violates the first condition.
C. 2, 3, 4, 5, 6: Classroom 2 is selected, so classroom 6 must also be selected, and it is selected here, so the third condition is satisfied. Classroom 3 is selected, which means classroom 5 must also be selected, and it is selected, so the second condition is satisfied. There is no violation of any condition here, so
D. 2, 3, 4, 5, 7: Classroom 2 is selected, so classroom 6 must also be selected, but classroom 6 is not selected, which violates the third condition. Therefore, Option D is not valid.
Correct Answer is B
Explanation
A. accept the date enthusiastically: While it's great to stay open-minded, accepting the date without knowing anything about the person could lead to another disappointing experience if the connection doesn't feel right.
B. arrange to talk to the date by phone: This is the most reasonable option. By talking on the phone, you can get a better sense of the person's character, interests, and communication style. It also helps reduce the pressure of a blind date by allowing you to make a more informed decision.
C. make the decision based solely on your past experiences: Relying only on your past experiences could limit your chances of finding a good match. Just because your previous blind dates were difficult doesn’t mean the next one will be, especially since the new date is arranged by a family member.
D. turn the date down: Turning it down without considering the opportunity might be premature. If you don't take the chance to communicate first, you may be closing the door on a potentially good match.
