Final answer:
Creed, the agriscientist, would likely think that gloves and a respirator or mask are missing from the workers' protective gear to safely spray pesticides on a field.
Step-by-step explanation:
Observing the workers spraying pesticides on a cornfield, equipped with coveralls, hats, goggles, and rubber boots, agriscientist Creed might think that gloves and a respirator or a mask are the likely pieces of protective equipment missing. When working with pesticides, workers must protect all exposed skin and their respiratory system to prevent the inhalation or absorption of these potentially harmful chemicals. Given that pesticides can be hazardous, all safety measures, including appropriate attire and equipment, are necessary to minimize health risks.
