Reading the passage
Read “knowledge systems” with the sentence before it in mind. Farmers preserve seeds, and they also pass down what they know about developing and cultivating the crops. Here we need that practical knowledge, not the physical seed stock or techniques imported from elsewhere.
Working the answers
- A
These methods were developed and maintained by indigenous farmers. The researchers' recent recognition of their value doesn't make the researchers their creators.
- B
Passing on seeds preserves plant material. The expression asks about knowledge: how to breed and raise the plants. Those two forms of preservation are related, but they aren't interchangeable.
- C
The relevant techniques come from indigenous farming knowledge. This reverses their source by calling them techniques brought to North America from elsewhere.
- DCorrect
Breeding and raising heirloom varieties are the development and cultivation methods described in the final paragraph. Hybridizing corn and selecting plants suited to local conditions are concrete examples of the knowledge being preserved.
- E
“Fail-safe” promises success the author never guarantees, and farming operations generally are broader than the specific heirloom knowledge under discussion. Valuable methods don't become a guarantee that any farming operation will succeed.
