Evaluate Evidence for Social Behavior Advantages Practice Test

Claim: Group living increases survival.

Evidence from a controlled comparison in the same habitat:

• Survival after 6 months: groups (n = 80 individuals) = 61 survivors; solitary (n = 80 individuals) = 60 survivors.
• Average food intake per day was slightly higher in groups.

Which choice best evaluates whether the evidence supports the claim?

Claim: Social learning (learning from others) helps individuals gain a new foraging skill faster than learning alone.

Evidence:

1. In a lab test, juveniles that watched a trained adult opened a puzzle feeder in an average of 3 days; juveniles tested alone took an average of 8 days.

2. In the same population, individuals with brighter fur had higher mating success.

3. In one anecdote, a single juvenile opened the feeder on the first day without watching anyone.

Which piece of evidence is least relevant to evaluating the claim?
