While researching a topic, a student has taken the following notes:
<ul> <li>To estimate population sizes of fish, biologists use mark-recapture or hydroacoustic surveys.</li> <li>Mark-recapture: capture, tag, release, then sample again later to estimate population.</li> <li>Hydroacoustic: use sonar to count fish from a boat in real time.</li> <li>Mark-recapture is labor-intensive and stressful for animals.</li> <li>Hydroacoustic is faster but cannot identify species reliably.</li> </ul> The student wants to contrast the two methods' tradeoffs. Which choice most effectively uses relevant information from the notes to accomplish this goal?Which choice most effectively makes the student's point?
- A
Hydroacoustic surveys use sonar from a boat.
- B
Both methods estimate fish populations.
- C
Mark-recapture involves tagging fish.
- Dcheck_circle
Mark-recapture is labor-intensive and stressful for animals; hydroacoustic is faster but cannot reliably identify species.
Explanation
The goal is methodological tradeoffs. Choice B pairs each method's downside. A is similarity, C and D describe one method each.
