Final answer:
The most likely cause of the spread of illness in this scenario is cross-contamination, which can be prevented by practicing proper hand washing techniques.
Step-by-step explanation:
The most likely cause of the spread of illness in this scenario is cross-contamination. Cross-contamination occurs when germs from one surface or object are transferred to another surface or object. In this case, June is holding her sniffling baby while hugging her toddler with a scraped knee, potentially transferring germs from the baby to the toddler or to the food she is preparing.
To prevent the spread of illness, it is important to practice proper hand washing techniques. June should wash her hands thoroughly with soap and water before and after handling her baby, her toddler, or any food items. This will help reduce the risk of transferring germs and prevent the spread of illness.
