Reading the passage
What is the author trying to get us to support? Preserving indigenous knowledge and using it to protect crop diversity. The account explains why that approach is valuable and why action is needed now. It doesn't announce a perfect solution or claim that the author invented the approach.
Working the answers
- A
Some current agricultural practices are criticized, but they create the problem discussed at the start. The author's central purpose is to support a conservation approach, not criticize current efforts to solve the problem.
- B
The discussion contrasts vulnerable commercial practices with diverse heirloom crops. That isn't a comparison of two competing proposed solutions. It explains the problem and develops one promising response.
- C
Indigenous methods have a long history, and the first paragraph already describes researchers looking to heirlooms as a possible resource. The author supports that effort rather than presenting a newly invented solution. Recent recognition of old knowledge isn't a claim to originate the proposal.
- D
“Definitive” goes beyond the evidence. The author gives reasons the approach could help and urges its adoption; nothing establishes that it completely and conclusively solves the agricultural problem.
- ECorrect
The explanation of diversity, natural resistance, and local adaptation supports a promising approach to the narrowing genetic base. The final call to preserve and integrate the knowledge makes that advocacy explicit.
