  1. Which four spectral bands are typically included in USDA Farm Service Agency four-band imagery?
    • Red, green, blue and near-infrared
    • Ultraviolet, X-ray, thermal and radar
    • Only red and near-infrared
    • Blue, ultraviolet, microwave and lidar
  2. John Deere の See & Spray はどのようにして除草剤の使用を削減しますか?
    • 圃場全体に均一に散布することで
    • コンピュータビジョンを使用して、検出された雑草のみを散布する
    • あらゆる除草剤を禁止することで、
    • 夜だけスプレーすることで
  3. 精密農業における「変動率技術」とは何ですか?
    • 農家に種子の異なる価格を請求する
    • トラクターの速度をランダムに変更する
    • 異なるフィールドゾーンに異なる量の入力を適用する
    • 作物保険の一種
  4. Which model architecture did the cited 2025 crop-weed paper evaluate for edge weed detection?
    • A speech-recognition Transformer
    • A rule-only spreadsheet parser
    • A large language model trained on contracts
    • A lightweight convolutional neural network
  5. In the USDA ERS 2023 report, variable-rate technology had been adopted on what share of planted acreage for winter wheat, cotton, sorghum and rice?
    • Between 5 and 25 percent
    • Less than 1 percent for every crop
    • Between 50 and 75 percent
    • All planted acreage
  6. What did the cited USDA precision-farming field study report about yield patterns across years?
    • Yield patterns were identical every year
    • Yield patterns changed yearly and had little similarity between years
    • All management zones produced the same yield
    • AI consistently improved yield in every zone
  7. How is NDVI commonly calculated from red and near-infrared reflectance?
    • Red plus blue divided by soil moisture
    • Thermal radiation minus wind speed
    • Near-infrared minus red, divided by their sum
    • Plant height multiplied by fertilizer rate
  8. Why can variable-rate technology use input maps instead of a single field-wide rate?
    • Every part of a field has identical needs
    • Maps eliminate the need for agronomic decisions
    • The system changes crop genetics while spraying
    • Soil and crop conditions can vary across zones within a field
