Perhaps the most serious concern about the transgenic crop plants currently in use is that they encourage farmers to move farther away from sustainable agricultural farming practices, meaning ones that allow natural resources to continually regenerate over the long run.
Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?
- Transgenic crop plants may be used in place of other, more sustainable agricultural practices, and this is perhaps their biggest disadvantage.
- Perhaps the most serious concern about the transgenic crop plants currently in use is the possibility that they may not be sustainable over the long run
I think the first option is better. And the second option is inherently flawed because it says "transgenic crop plants are not sustainable"; however the original sentence is saying "natural resources to continually regenerate".
But the answer is the second one.
