Despite all obstacles (a) I will complete (b) this training on (c) self control by next month (d) [No error]

It's a question from a test. One of the bold sections is erroneous or there is no error.

I was unable to find any error but the answer says (b). With no explanation given, I do not understand why it is wrong and what should it be.

  • I understand you found some punctuation to be incorrect, but *Despite all obstacles, I will*[..] has been taken verbatim from the original question. In this case I presume it will be better revert to the previous form, although it might be incorrect.

Knowing this sort of test, I know what they want you to do.

The last part says "by next month", so the verb form they want is "will have completed".

The alternative is to change "by next month" to "next month" (but this changes the meaning to match the grammar, not the grammar to match the meaning, so is not what the test writers want you to do)

It is debatable if this is actually a mistake, but the future perfect form does go naturally with a "by {time}" phrase.

    I like your guess.. an upvote from me; however, It actually is really debatable.. that is: we have to clearly define the discrepancy between "I will finish it by next month" vs. "I will finish it next month". Semantically, there smells to be a point, that "by next month" implies no later than that.. yet, it's blurry to draw a sharp line in between. Commented Oct 4, 2020 at 21:51
  • Thank you. This conforms to the answer given. I wasn't aware of such grammar rules, which made me unable to understand the answer.
