Answer:
"The conservation movement was somewhat internally divided between naturalists who stressed the preservation of natural spaces and those who stressed managed exploitation of those resources" is TRUE.
Explanation:
The primary objective of naturalists is to raise public awareness regarding the current environment and to preserve the natural environment on land predominantly established for wildlife populations.
A conservationist protects natural environment namely parks, forests, and grasslands. This profession may also be called a water and soil conservationist or a conservation scientist. This sustainable career is only about finding creative ways to use land without destroying the planet. Therefore both naturalist and conservationist are two individual divisions of conservation movement.
