12 Days of Christmas 🎅 GMAT Competition with Lots of Questions & FunPublic Health Official: A recent study concludes that the new public park in Downtown Metroville has not contributed to an overall improvement in residents' physical fitness. This conclusion is based on a citywide survey showing no significant change in average weekly exercise hours reported by residents after the park's opening. However, this conclusion may be too simplistic. The same period saw a substantial increase in the number of gyms and fitness centers across Metroville. Additionally, there was a marked rise in the use of online fitness programs, likely due to the recent expansion of high-speed internet services in the area.
In this passage, the public health official attempts to challenge the study's conclusion by:
(A) pointing out the limitations of the study's scope in assessing the impact of the public park on physical fitness.
(B) suggesting that the study's reliance on self-reported data might not accurately reflect the actual change in residents' physical fitness.
(C) introducing additional factors that could have influenced the citywide physical fitness trends during the same period.
(D) questioning the validity of using the number of weekly exercise hours as a measure of physical fitness.
(E) arguing that the study's timeframe was not sufficient to capture the long-term impact of the public park on residents' fitness.
GMAT Club's Official Explanation:
(C) Introducing additional factors that could have influenced the citywide physical fitness trends during the same period.
- The public health official highlights two key developments: the increase in the number of gyms and fitness centers across Metroville, and the rise in the use of online fitness programs. These points suggest other reasons for the lack of change in average weekly exercise hours as reported in the study, challenging the conclusion that the public park hasn't contributed to an improvement in physical fitness. This approach introduces other variables that could have impacted the overall physical fitness of residents, thereby questioning the direct linkage between the park's opening and the citywide fitness levels.
The other options, while plausible, do not as closely match the strategy used by the public health official in the passage:
(A) Pointing out the limitations of the study's scope in assessing the impact of the public park on physical fitness.
- The official does not directly critique the scope of the study.
(B) Suggesting that the study's reliance on self-reported data might not accurately reflect the actual change in residents' physical fitness.
- The official does not specifically address the reliability of self-reported data.
(D) Questioning the validity of using the number of weekly exercise hours as a measure of physical fitness.
- The official does not challenge the metric of weekly exercise hours itself.
(E) Arguing that the study's timeframe was not sufficient to capture the long-term impact of the public park on residents' fitness.
- The official does not comment on the sufficiency of the study's timeframe.
Hence, (C) is the correct answer as it best describes how the public health official challenges the study's conclusion.
