Question 1: If the lead engineer had noticed the design flaw earlier, the team ______ on a complete redesign of the product right now.
- would not have worked
- did not work
- would not be working (Correct answer)
- will not be working
Correct answer: would not be working
This sentence requires a mixed conditional. The 'if' clause uses the past perfect ('had noticed') to describe a hypothetical past condition, while the main clause describes the present result of that condition. Therefore, the present conditional form ('would not be working') is correct.
Question 2: The project manager was scheduled ______ the final presentation to the board last Friday, but it was postponed due to unforeseen circumstances.
- to have given (Correct answer)
- to give
- giving
- to be giving
Correct answer: to have given
The perfect infinitive ('to have' + past participle) is used here to indicate that the action of giving the presentation was expected to be completed before the time of speaking.
Question 3: Which of the following sentences correctly uses the subjunctive mood for a formal recommendation?
- The report recommends that the company invests more in research and development.
- The report's recommendation is that the company is investing more in R&D.
- I would recommend that the company will invest more in its R&D department.
- The report recommends that the company invest more in research and development. (Correct answer)
Correct answer: The report recommends that the company invest more in research and development.
The subjunctive mood is used after verbs of recommendation, suggestion, or demand (like 'recommends that'). It requires the base form of the following verb ('invest'), regardless of the subject.
Question 4: By the time the new CEO took over, the marketing team ______ on the rebranding strategy for nearly six months.
- was working
- had been working (Correct answer)
- has been working
- worked
Correct answer: had been working
The past perfect continuous ('had been working') is the correct tense to describe a continuous action that started in the past and continued up until another point in the past ('the time the new CEO took over').
Question 5: The final audit is completely clean. The finance department ______ any errors when they prepared the initial report.
- shouldn't have made
- could not make
- might not make
- must not have made (Correct answer)
Correct answer: must not have made
Perfect modals are used to make deductions about the past. 'Must not have made' expresses a strong logical conclusion (near certainty) that no errors were made in the past, based on the present evidence of a clean audit.
Question 6: To comply with the new regulations, the corporation had all of its international contracts ______ by a team of legal experts.
- reviewed (Correct answer)
- reviewing
- to review
- review
Correct answer: reviewed
This sentence uses the causative passive structure 'have something done' (had all of its...contracts reviewed). This form is used when the subject arranges for an action to be performed by someone else. The correct verb form is the past participle.
If the lead engineer had noticed the design flaw earlier, the team ______ on a complete redesign of the product right now.
