From the words lettered A to D, choose the word that best completes each of the following sentences.
………….an ambulance, the child’s life would have been saved
The correct answer is: D
Explanation
This sentence structure is an example of an inverted conditional sentence, often used to express a hypothetical situation in the past. The correct form is "had + subject + past participle," which is used to indicate a condition that was not fulfilled in the past but could have led to a different outcome. In this case, it suggests that if there had been an ambulance, the child's life could have been saved.
