Prompt
Act as a pesticide safety education instructor and exam item writer who prepares commercial and private applicators for the state core certification exam using the National Pesticide Applicator Certification Core Manual. Inputs: - State and certification type (commercial core, private applicator, or recertification review): [StateExam] - Core Manual chapters to cover with the weight for each: [ManualChapters] - Number of items and difficulty mix (recall, application, calculation): [ItemCount] - Calculation item types to include (broadcast sprayer calibration, 1/128 acre method, tank mix amount from label rate, percent active ingredient): [MathItems] - Real label excerpts the class is using, if any: [LabelExcerpts] - Delivery format (paper, Moodle GIFT, Google Forms): [ItemFormat] Generate: 1. A blueprint table that spreads ItemCount across ManualChapters by weight, with the cognitive level for each item. 2. Original four choice items written in plain applicator language, one correct answer, three plausible distractors built from real mistakes (confusing REI with PHI, reading Caution as nontoxic, rinsing containers once instead of three times). 3. Label comprehension items that use LabelExcerpts when given, asking where to find PPE, first aid, storage, and restricted use status, never inventing a product name or EPA registration number. 4. MathItems calculation items with the setup worked out step by step in the rationale, using round numbers an applicator could do with a calculator in the field. 5. Scenario items on drift, spill response (control, contain, clean up), and protecting water and pollinators. 6. For every item: the key, a one line reason the key is right, a one line reason each distractor is wrong, and the Core Manual chapter tag. 7. The set rendered in ItemFormat, then a short list of topics StateExam adds beyond the core (state laws, recordkeeping) for the instructor to cover separately. Constraints: - Write new items only; never reproduce real exam questions or claim an item appears on the exam. - The label is the law: rationales point back to the label, not to shortcuts. - Use generic product descriptions when LabelExcerpts is empty. No em dashes.

Example Output
BLUEPRINT (5-item preview) | # | Chapter | Level | | 1 | Ch 3 Labeling | Recall | | 2 | Ch 4 Toxicity | Application | | 3 | Ch 6 PPE | Application | | 4 | Ch 11 Calibration | Calculation | | 5 | Ch 8 Spills | Recall | ITEMS 1. On a pesticide label, the reentry interval (REI) tells you: A. How long to wait between harvest and the last application B. How long workers must stay out of a treated area unless wearing early entry PPE C. How long the product stays effective after mixing D. How long to wait before reapplying 2. A label carries the signal word CAUTION. What does that tell you? A. The product is nontoxic and needs no PPE B. The product is in a lower toxicity category, but the label PPE still applies C. The product is a restricted use pesticide D. The product is highly toxic by the oral route only 3. The label says "chemical resistant gloves" for mixing and loading. Which choice follows the label? A. Leather work gloves B. Cotton gloves under latex gloves C. Nitrile gloves of the type the label or its glove chart lists D. No gloves if you keep your hands out of the tank 4. Using the 1/128 acre method, you mark a course sized for your boom, spray it, and collect 32 ounces of water from one nozzle in the time it took to cover the course. What is the output? A. 32 gallons per acre B. 16 gallons per acre C. 64 gallons per acre D. 128 gallons per acre 5. After a small liquid spill in the shop, what is the correct order? A. Clean up, contain, control B. Contain, control, clean up C. Control, contain, clean up D. Call the manufacturer, then clean up KEY AND RATIONALES 1. B. The REI is the worker protection time on the label. A describes the PHI. C and D are not what REI means. (Ch 3) 2. B. Caution is the lowest signal word, not "safe." A is the classic mistake. C: restricted use status is a separate statement. D: signal words cover the most toxic route, not oral only. (Ch 4) 3. C. Follow the label glove type. A and B absorb pesticide. D ignores the label. (Ch 6) 4. A. In the 1/128 acre method, ounces collected from one nozzle equal gallons per acre because there are 128 ounces in a gallon. B, C, D come from halving, doubling, or multiplying by 4. (Ch 11) 5. C. Stop the source first, keep it from spreading, then clean up. (Ch 8) STATE TOPICS TO COVER SEPARATELY Ohio pesticide law, recordkeeping for commercial applications, and license category rules.
