      "Question": "Which storage method best helps prolong the freshness of apples after harvest?",
      "Answer": "A",
      "Explanation": "Apples store best in a cool (near 0–4°C or 32–40°F), humid environment such as a refrigerator crisper or a cool cellar. Low temperature slows ripening and reduces decay. Apples produce ethylene gas, so storing them with ethylene-sensitive produce (or keeping them away from fruits like bananas if you want to slow ripening) matters.",

      "OptionB": "Keep them at room temperature next to bananas to speed ripening",
