The passage given below is followed by four summaries. Choose the option that best captures the essence of the passage.
For millennia, in the process of opening up land for agriculture, gardens, grazing and hunting, humans have created ecological "mosaics", or "patchworks": landscapes holding a mixture of habitats, like meadows, gardens and forests. These were not designed as nature reserves, but often catered to hugely diverse animal life. Research indicates that European hay meadows cultivated for animal feed were actually more successful at preserving a vast array of species than meadows explicitly cultivated for biodiversity. Studying the early Holocene, researchers have found that human presence was about as likely to increase biodiversity as reduce it. Of course, not all human-created landscapes have the same value. A paved subdivision with astroturfed lawns is very different to a village with diverse vegetable and flower gardens. But scientists continue to find evidence that the old idea of humans as antithetical to nature is also wrong-headed, and that rosy visions of thriving, human-free environments are more imaginary than real.
Answer: D
The passage argues three things. Humans have long created mixed habitats ("mosaics") that support diverse species. Human presence "was about as likely to increase biodiversity as reduce it". So the idea of humans as opposed to nature, and visions of thriving human-free environments, are wrong. Option D covers all of this: it rejects both the "humans hurt nature" view and the human-free ideal, gives the even odds, and mentions varied landscapes supporting many species.
- Option A takes the single hay-meadow finding and turns it into a general claim that human landscapes beat purpose-built reserves, and it leaves out the main argument against the humans-versus-nature view.
- Option B says human action "assists the preservation of meadows", a distortion, and drops the even-odds and human-free points.
- Option C credits everything to Holocene studies and overstates the conclusion, ignoring the caveat that not all human landscapes have equal value.
Hence, the answer is (D).
