Fill in the blank in the following sentence with suitable option. He was hit…

Answer: He was hit by a car along the road.

Key point: Use 'by' to introduce the agent in a passive sentence; use 'along' to indicate location or movement alongside the length of the road.

• Why 'by'?

  'By' introduces who or what performed the action in passive voice: 'hit by a car' means the car was the agent that hit him.

• Why 'along'?

  'Along the road' indicates location or movement along the road's length (for example, while walking along the road). 'On the road' is also grammatical but emphasizes being on the road surface rather than alongside or along its length.

Brief notes on the other options:

• 'with; along' is incorrect because 'with' is not the usual preposition to name the agent in passive constructions; it typically indicates an instrument.

• 'in; in' is incorrect because 'in a car' would change the meaning (he would be inside a car), and 'in the road' is unidiomatic here.

• 'by; on' is grammatical ('hit by a car on the road') but the expected phrasing uses 'along' to convey location/direction along the road, which fits the intended meaning better.

Tip: In passive sentences, ask 'who/what did it?' to decide whether to use 'by' for the agent; choose between 'on', 'in', and 'along' based on whether you mean surface location ('on'), being inside ('in'), or movement/position along the length ('along').
