While researching a topic, a student has taken the following notes:
<ul> <li>Researchers studied stress responses in two ways.</li> <li>Approach 1 measured cortisol levels in saliva at fixed times of day.</li> <li>Approach 2 measured continuous heart-rate variability via wearables.</li> <li>Approach 1 captured daily peaks but missed brief stressors.</li> <li>Approach 2 captured brief stressors but produced large data volumes.</li> </ul> The student wants to contrast the strengths of the two approaches. 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 approaches measured stress responses.
- B
Approach 2 produced large data volumes.
- Ccheck_circle
Whereas salivary cortisol captured daily peaks, continuous heart-rate variability captured brief stressors.
- D
Approach 1 measured cortisol levels in saliva.
Explanation
The goal is contrasting strengths. Choice C names what each approach captures best. A names a downside, B is similarity, D describes one approach.
