Based on the 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?

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

Accepted Answer

Correct Option: Sometimes, the campaigns against foreign plants are pointless. The passage argues that most invasive species are neither very successful nor very harmful, often increasing biological diversity without driving native species to extinction, and acting as nature's opportunists in disturbed habitats where little else lives. From this, it can be logically inferred that extreme fear or generalized campaigns against all foreign plants or invasive species can sometimes be pointless, since they are not inherently disastrous and often occupy wasteland. Thus, option 3 is the most logical and rational inference.
