Bob, an orange grower new to the industry, heard on the news that there was a forecast of freezing temperature for the low next morning. He hadn't picked his oranges yet because it was too early in the season and he was worried that he would lose everything. It seemed that he was doomed. John, a worker of his who was still in high school, came up with a plan. He told Bob that he learned of a way to protect his crops from freezing. All he needed was access to the watering hose. What did John do?
