sorry expert, don’t get you well. How should I comprehend this sentence: plants most at risk have [i]ALL FOUR of the following characteristics: a short life span, a narrow geographic range, an incapacity for vegetative propagation, and a dependence on a small number of insect-pollinator species.
I think at risk means a disadvantage. Mind to explain further? Thanks
What the passage DOES NOT say:
The fecundity effects described here are likely to have the most profound impact on plant species with AT LEAST ONE of the following characteristics: a short life span, a narrow geographic range, an incapacity for vegetative propagation, and a dependence on a small number of insect-pollinator species.Here, the phrase in red conveys that -- for a plant to be profoundly affected by pesticide use -- it must have AT LEAST ONE of the four characteristics.
As a result, there will be a profound effect on a plant that has a short life span but that lacks the other three characteristics.
What the passage ACTUALLY says:
The fecundity effects described here are likely to have the most profound impact on plant species with ALL FOUR of the following characteristics: a short life span, a narrow geographic range, an incapacity for vegetative propagation, and a dependence on a small number of insect-pollinator species.Here, the phrase in blue conveys that -- for a plant to be profoundly affected by pesticide use -- it must have ALL FOUR characteristics.
As a result, there will NOT be a profound effect on a plant that has a short life span but that lacks the other three characteristics.
C: A flowering tree that is short-livedThis option refers to a short life span but does not mention the other three characteristics.
As a result, there is no indication that the flowering tree will be profoundly affected by pesticide use.
