While researching a topic, a student has taken the following notes:
<ul> <li>Two epidemiological studies investigated air pollution and asthma.</li> <li>Study M used hospital records cross-referenced with daily air quality readings.</li> <li>Study N used personal exposure monitors worn by participants for two weeks.</li> <li>Study M covered tens of thousands of patients but used estimated exposures.</li> <li>Study N covered fewer than 100 participants but measured exposure precisely.</li> </ul> The student wants to contrast the strengths of the two methodologies. Which choice most effectively uses relevant information from the notes to accomplish this goal?Which choice most effectively makes the student's point?
- A
Both studies investigated air pollution and asthma.
- B
Study M had more participants.
- C
Study N used wearable monitors.
- Dcheck_circle
While Study M's hospital-record approach reached tens of thousands of patients with estimated exposures, Study N's wearable monitors provided precise exposures for fewer than 100 participants.
Explanation
The goal is methodological strengths. Choice C names each method's distinct trade. The others state similarities or one feature.
