In a scientific study of racehorses that were fed an iron rich diet for six months, 75% of the horses showed an increase in track speed within 90 days. That this improvement could have happened randomly or by chance was ruled out with a high degree of confidence. If the above statements are true, the study's statistical findings confirm:
the horses in the study were racehorses and the findings do not apply to horses in general.
iron rich feed is associated with an increased track speed in racehorses.
regulations regarding the type of dietary intake for racehorses should be enforced.
regular, non-iron enriched feed causes decreased track speed in racehorses.
The Correct Answer is B
A. the horses in the study were racehorses and the findings do not apply to horses in general: The study specifically involved racehorses, so this statement is true, but it doesn’t directly address the core finding of the study, which is the relationship between iron-rich diet and increased track speed.
B. iron rich feed is associated with an increased track speed in racehorses: The study shows that 75% of the horses showed improved track speed after receiving an iron-rich diet, indicating an association between the two variables.
C. regulations regarding the type of dietary intake for racehorses should be enforced: The study doesn’t suggest that regulations are necessary; it only shows an association. The study does not provide enough information to make regulatory recommendations.
D. regular, non-iron enriched feed causes decreased track speed in racehorses: The study does not discuss non-iron-enriched feed or make any claims about its effect on racehorse speed. The study only examined the effects of an iron-rich diet, not the comparison with other types of feed.

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 C
Explanation
A. This advertisement clarifies that only those that want to look younger should buy the product: This is not an accurate critical evaluation. The advertisement doesn't limit the target audience to only those who want to look younger; it simply suggests the product may help with that.
B. The name of the product indicates the product contains healthy ingredients: The product name, Neutrasplash, does not necessarily indicate anything about the ingredients or their health benefits. This statement is a speculative assumption, not a critical evaluation of the advertisement.
C. The phrase "helps prevent" eliminates any promises about the performance of this product: This is the best evaluation. The use of "helps prevent" is a vague phrase that does not guarantee the product’s effectiveness. It suggests that the product might offer some benefit, but it doesn’t make a firm promise, making the advertisement less definitive about its performance.
D. This advertisement gives several good reasons for purchasing the product: This is not true. The advertisement does not provide any concrete reasons or evidence for purchasing the product; it only makes a general claim about preventing lines and wrinkles without offering specific details or proof.
