The other driver was fast and ().

• A. Careless
• B. Careful
• C. Reckless
• D. Distracted

Answer: (A)

This item tests which adjective best completes a description of dangerous driving by pairing speed with a lack of caution. The natural finish is care less because it directly conveys driving fast while not paying enough attention, highlighting unsafe behavior in a concise way. Saying the driver is careful would contradict the idea of danger, and while reckless is possible, it tones the sentence more intensely than intended. Distracted describes a mental state rather than a clear driving behavior and doesn’t fit the smooth, typical contrast with fast in this construction.
