Sentence improvement — Passive voice for penalties: determine whether ‘‘He was fined for careless driving.’’ already uses the correct passive construction and therefore requires no change.

Given data
He was fined for careless driving.

Concept/Approach
Official penalties are commonly reported in the passive: ‘‘was fined’’. It is concise, formal, and correct.

Option analysis
got fined — Colloquial; less formal.fined — Bare past-participial fragment if used alone; the given sentence already has a complete passive clause.was to be fined — Indicates future-in-the-past intention, not actual imposition.No improvement — Keeps the proper passive.

Verification/Alternative
Active alternative: ‘‘The court/police fined him for careless driving.’’ Passive is perfectly natural here.

Common pitfalls
Assuming ‘‘got + past participle’’ is acceptable in formal exam English; prefer be-passive for penalties.

Final Answer
No improvement
