Difficulty: MediumVerbs, Tenses, and Aspect

Read the excerpt below from an official report on maritime operations:

'If the navigation officer _______ the weather advisory before setting sail, the vessel would not have encountered the severe storm.'

Which of the following options correctly completes the sentence?

  1. A
    received
  2. had receivedAnswer
  3. C
    would have received
  4. D
    has received

Answer

The past perfect verb form 'had received' correctly completes the conditional clause.
The sentence represents a standard third conditional construction. In third conditional sentences, the condition clause introduced by 'if' must take the past perfect tense ('had received') to pair correctly with the past modal perfect ('would not have encountered') in the main clause.

Step-by-Step Solution

1
Identify the conditional structure of the sentence.
The sentence presents a third conditional (past counterfactual) scenario, evidenced by the result clause 'would not have encountered'.
A third conditional describes an unreal past situation and its hypothetical outcome in past time.
2
Determine the required verb tense for the subordinate conditional clause.
The dependent clause introduced by 'if' requires the past perfect structure ('had' + past participle).
Standard grammatical rules dictate that an 'if'-clause expressing an unfulfilled past condition must use the past perfect tense.
