Theme-park spokesperson: We regret that four visitor fatalities occurred last year in separate accidents at our company’s theme parks. All four deaths involved roller coasters on which riders stand rather than sit, and all victims were children under age 12. We have since closed down all of our “standing” roller coasters, and our new policies prohibit any child under age 12 from riding any of our coasters. I can confidently state that all coasters currently operating at our parks are perfectly safe for
any person age 12 or older.
Which of the following investigations would be most useful in evaluating the spokesperson’s safety assessment of the roller coasters currently operating at the company’s parks?
(A) Surveying park visitors to determine the extent to which they are concerned about their safety when riding roller coasters
(B) Determining the specific cause of death in the case of each of the four roller-coaster accidents
(C) Comparing industry-wide safety records for “standing” roller coasters to safety records for coasters in which riders sit
(D) Scrutinizing the repair and maintenance records for the roller coasters involved in the fatal accidents
(E) Determining the incidence of nonfatal accidents involving all roller coasters at the company’s parks that are currently in operation
The theme park spokesperson begins with a remorseful note that the death of 4 visitors at the theme park is regrettable.
The spokesperson further adds on saying :
1) All the four deaths happened were due to standing roller coaster and NOT sitting roller coasters,
2) The 4 deaths were all children below the age of 12 years.
Finally, the spokesperson adds a few lines to support his conclusion - by stating the new rules of the theme parks - prohibit children below 12 years to ride any roller coaster. And, Standing roller coaster’s are closed from access inside theme park.
The conclusion is : “ All roller coasters currently in operation is safe for children above 12 yrs of age”.
Which of the following investigations would be most useful in evaluating the spokesperson’s safety assessment of the roller coasters currently operating at the company’s parks?
(A) Surveying park visitors to determine the extent to which they are concerned about their safety when riding roller coasters.
This might be helpful, when the visitors have earlier been and experienced this theme park. And are able to feel the difference post stopping standing roller coasters. Moreover, the experience that the visitors enjoy is emotional in manner, but we are speaking about the safety and security of the park. Hence, wrong.
(B) Determining the specific cause of death in the case of each of the four roller-coaster accidents.
The specific cause of death might be varied in nature, and the cause of death may be helpful in ascertaining the roller coaster accident. It might in useful to provide insights on future steps to be taken to prevent such incidents. But, is the roller coaster now safe. This option cannot evaluate this criteria. Hence, wrong.
(C) Comparing industry-wide safety records for “standing” roller coasters to safety records for coasters in which riders sit.
This might provide a comparative list, but does this help us evaluate the current conditions of the roller coaster used inside the theme park. This remains a billion dollar question. Hence, wrong.
(D) Scrutinizing the repair and maintenance records for the roller coasters involved in the fatal accidents.
To scrutinise the repair snd maintenance of the roller coaster, firstly we should be experts in that field to know and understand it. Secondly, postmortem on an event, might be helpful in identifying, preparing new processes and guidelines. But, does it testify the working condition of the current roller coaster.? Hence, wrong.
(E) Determining the incidence of nonfatal accidents involving all roller coasters at the company’s parks that are currently in operation.
This approach helps us identify the number of past accidents that has happened in the roller coasters currently in operation. The number of incidents of non fatal accidents might help us determine whether the roller coaster is essentially safe OR is it prone to accidents in the future. The claim of perfectly safe remains doubtful. Hence, Correct answer.
