Sentence Correction: Tenses - Past Simple and Progressive

Last year, John promised Jane that he will take her to the opera on their anniversary.

Incorrect.

This answer choice is grammatically incorrect. In Reported Speech, when the reporting verb is in the Past tense (promised), the following conjugated verbs should also be in the Past. However, will take is in the Future.

Incorrect.

This answer choice is grammatically incorrect. The sentence begins with a specific time indication "last year". In the case of an action that happened in the past at a specific time, Past Simple is the correct tense. Thus, the use of the Present Perfect "has promised" is incorrect.

Did you notice the change from the original sentence's promised to this answer choice's has promised?

The lesson to be learned here is the importance of paying close attention to details in the answer choices.

Do not assume that the only thing that changes in the answer choices is the part which was flawed in the original sentence. Different answer choices can make changes in various parts of the sentence.  

Incorrect.

This answer choice is grammatically incorrect. The sentence begins with a specific time indication "last year". In the case of an action that happened in the past at a specific time, Past Simple is the correct tense. Thus, the use of the Present Perfect "has made" is incorrect.

Good!

In Reported Speech, when the reporting verb is in the Past tense (promised), the following conjugated verbs should also be in the Past (would take).

Incorrect.

While this answer choice corrects the original sentence and is grammatically correct, it doesn't fit into the original sentence as a result of the omission of the word her.

In that case, you should have stopped to ask yourself why the change was made. Did it improve the sentence or make it worse? In this case, you should have applied the rules concerning the use of tenses to determine whether the use of Present Perfect was suitable.
