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 C
Explanation
A. consider stoplights important: While it is reasonable to assume that police officers might consider stoplights important as part of maintaining the law, the original statement does not directly imply this. It focuses on the legality of running a stoplight rather than the officers' personal views.
B. believe it is illegal to run a stoplight: The statement implies that police officers enforce the law, but it doesn’t necessarily indicate what they believe. The focus is more on their role in maintaining the law rather than their personal belief about the law.
C. may issue a ticket if you run a stoplight: This is the best interpretation. Since the statement mentions that police officers maintain the law and that running a stoplight is illegal, it logically follows that police officers may take action, such as issuing a ticket, if someone violates this law.
D. never run stoplights: This is not a valid conclusion. The statement does not make any claims about the actions of police officers in relation to stoplights, only their role in enforcing the law. They may run stoplights, but they would be subject to the same legal consequences as anyone else.
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.
