The passage describes the gradual enhancement of life on the island, particularly benefiting birds like Antarctic prions and white-headed petrels. It emphasizes the increasing population of these birds as pest control measures are implemented on the island. With pests under control, the birds can return, breed, and contribute positively to the ecosystem. Additionally, the passage notes how bird droppings enrich the soil with nutrients, promoting plant growth.
Overall, Option D effectively encapsulates the central theme of the passage: the rejuvenation and enhancement of island life due to pest eradication and its positive effects on birds and plants.
Option A erroneously suggests a rise in predatory bird numbers, contradicting the positive developments outlined in the passage.
Option B is inaccurate as the passage does not explicitly attribute the positive changes solely to this protection measure.
Option C is more general and does not specifically highlight the absence of pests as a critical factor in the positive transformation described in the passage.
So, the correct option is (D): In the absence of pests, life on the island is now protected, and there has been a revival of a variety of birds and plants.
