THE GREEN LEMONS
For years, a California warehouse had stored freshly picked green lemons before they were shipped to market. The warehouse managers knew that the lemons would be a ripe yellow and ready to ship to market about five days after they arrived. Or so they thought. One year, for safety reasons, they decided to replace the warehouse's kerosene heaters with modern electric ones. Then, to their astonishment, when they began to pack their first shipment of five-day-old lemons, they had to call a halt. The fruit they expected to ship were still a bright, and very unripe, green. What had happened? As you read the chapter, look for clues that provide information about the case of the green lemons. Solve the mystery.
