Answer 1

The correct answer is:**Created cross-connection**### Explanation:A **cross-connection** occurs when there is a physical link between safe (potable) water and contaminated water, such as wastewater or dirty water. In this scenario, the food handler dropped the end of the hose into the mop bucket, which contains potentially contaminated water. If there is a drop in water pressure (e.g., from a sudden demand elsewhere in the system), it could cause **backflow**, where contaminated water from the mop bucket is drawn back into the clean water supply.To prevent this, an **air gap** (a physical separation between the water supply outlet and the surface of the water in the container) should always be maintained. Alternatively, backflow prevention devices can also be used to avoid contamination.
