Confused about answer

Thank you for pointing this out. You are correct in pointing out that answer choice (D) should be the correct answer. As you can see our liner notes in the review also point to answer choice (D) being the answer. The question stem asks us which of the following guarantees that a small farm will have buyers for all of their produce? Lines 21-25 state: "To help guarantee small farmers a market for all of their crops, Whatley encourages them to grow only crops that clients ask for, and to comply with clients requests regarding the use of chemicals," i.e. answer choice (D). Charging 60% of what supermarkets charge for the same produce--answer choice (B)--will merely encourage customers to go to the farm. But, the passage does not indicate that this would guarantee that the farmer would sell all of their produce. We have fixed this issue in the app. Thanks for bringing it to our attention! Please let us know if you have any other questions.
