Answer 1

Correct answers:
- In the Great Pacific Garbage Patch Study, researchers monitored plastic pollution in the ocean by collecting and analyzing samples from different locations.
- In the Great Smoky Mountains Study, researchers investigated psychiatric disorders in children by conducting yearly interviews and assessments without intervention.

Reason: Both involve observing and measuring phenomena without manipulating variables. The Good Samaritan and Harlow studies involved experimentally placing participants/monkeys into conditions, so they are experimental, not observational.
