The main idea of the urban biodiversity passage is that...

• A. Access to green spaces is as important as conservation.
• B. Biodiversity is best protected by restricting public access.
• C. Urban parks are too resource-intensive to maintain.
• D. Biodiversity should be prioritized over human recreation.

Answer: (A)

The main idea being tested is that protecting urban biodiversity goes hand in hand with giving people access to green spaces; the passage argues that conservation in cities is strengthened when residents can enjoy and connect with nature, not just when areas are locked away. This view treats public access as an integral part of sustaining biodiversity, since everyday interaction with urban nature helps people value and support conservation efforts. The other options don’t fit because they either push for restricting access, claim parks are too costly, or set up a false priority of biodiversity over recreation. The emphasis is on balancing protection with ongoing, accessible use of green spaces.
