What caused Beth to be late for work?

The correct answer, which indicates a traffic jam, highlights how external factors like road conditions can significantly impact an individual's punctuality. A traffic jam can be unpredictable, often caused by construction, accidents, or other unforeseen circumstances that delay travel times. This situation is relatable as many commuters experience similar delays in their daily routines, making it a common reason for being late to work.

In this context, while other factors such as a flat tire, oversleeping, or bad weather could also lead to tardiness, the implications of a traffic jam resonate with the frequent experiences of many individuals in urban environments. Thus, it provides a realistic scenario that explains why someone might not arrive at their workplace on time.
