Passage

Most invasive species are neither terribly successful nor very harmful. Britain’s invasive plants are not widespread, not spreading especially quickly, and often less of a nuisance than vigorous natives such as bracken. The arrival of new species almost always increases biological diversity in a region; in many cases, a flood of newcomers drives no native species to extinction. One reason is that invaders tend to colonise disturbed habitats like polluted lakes and post-industrial wasteland, where little else lives. They are nature’s opportunists.

Which one of the following is the most logical and rational inference that can be made from the above passage?

Select an option to attempt

Explanation

Statement A is incorrect. It goes beyond the passage, as it does not mention using invasive species for rehabilitating deserts or wastelands.

Statement B is incorrect. It is extreme; the passage does not imply that laws against foreign plants are entirely unnecessary.

Statement C is correct. The passage highlights that most invasive species are not particularly harmful, often less so than vigorous native species. It also mentions that invaders tend to colonize disturbed habitats where little else thrives, implying they fill ecological niches without necessarily causing harm. This suggests that campaigns against foreign plants may not always be necessary or justified, making C the most logical inference.

Statement D is incorrect. It generalizes the idea of using foreign plants for biodiversity, which is not supported by the passage.
