The following sentence contains an error. Find the part of the sentence which contains the error. When I (1) / complete (2) / my degree I (3) / take up (4) / this job. Correct Answer (4)

The correct answer is (4).

Key Points

  • The error lies in the part (4) of the sentence.
  • The given sentence is an example of First conditional sentences:
    • First conditional sentences are used to express situations in which the outcome is likely (but not guaranteed) to happen in the future. 
    • Example - If you rest, you will feel better.
    • Note that we use the simple present tense in the if/when-clause and simple future tense in the main clause—that is, the clause that expresses the likely outcome. 
  • In the given sentence, the job is not guaranteed but the person is likely to take up that job.
  • Thus, 'take up' will be replaced by 'will take up'.
  • Therefore, the correct sentence will be: When I complete my degree I will take up this job.


Hence, the correct answer is option (2).

Additional Information

  • There are four types of conditional sentences.
  • Let's look at the other three conditional sentences:
    • Zero Conditional Sentences - express general truths—situations in which one thing always causes another. 
      • Example - If you don’t brush your teeth, you get cavities.
      • The correct tense to use in both clauses is the simple present tense. 
    • Second Conditional Sentences - Second conditional sentences are useful for expressing outcomes that are completely unrealistic or will not likely happen in the future. 
      • Example - If I inherited a billion dollars, I would travel to the moon.
      • The correct way to structure second conditional sentences is to use the simple past tense in the if-clause and an auxiliary modal verb (e.g., could, should, would, might) in the main clause (the one that expresses the unrealistic or unlikely outcome). 
    • Third Conditional Sentences - used to explain that present circumstances would be different if something different had happened in the past.
      • Example - If you had told me you needed a ride, I would have left earlier.
      • When using the third conditional, we use the past perfect (i.e., had + past participle) in the if-clause. The modal auxiliary (would, could, should, etc.) + have + past participle in the main clause expresses the theoretical situation that could have happened.
