Statisticians have constructed many complex mathematical models designed to predict voter behavior, but since even the best of the models failed to correctly predict the winner in many of last year’s parliamentary races, in the coming years it is going to be improved in order to accurately forecast the results of the next election.
A - in the coming years it is going to be improved in order to more accurately forecast the results of the next election
B - over the coming years they will improve the model by enabling it to more accurately forecast the results of the next election

Please share OE. i DONT understand how "going to be " is correct for future action.Official Explanation is as follows:
(1) Take a First Glance (5 seconds)
All five answer choices begin differently, but the only topic hinted at by the initial splits is Pronouns (it vs. they). You’ll have to dig deeper to investigate the problems with the other answers.
(2) Read for Meaning
The main subject of this sentence is the best (of the mathematical models). Since of the models is a prepositional phrase, ignore it when you identify the subject. Like fish or species, the word best can be singular or plural (my best friend; the best movies of the year). It’s important to look for another clue to determine whether the appropriate pronoun is it or they; is there a non-underlined verb or pronoun that points to best, indicating whether it is singular or plural? The verb failed goes with best, but failed could be either singular or plural. It turns out that best can be singular or plural in this sentence; either interpretation is consistent with the rest of the sentence, so the it vs. they split is a red herring.
Scan the answers vertically to find another difference that you can use to evaluate the answers.
(3) Find a Starting Point
Start with any difference that seems easiest to you, then move to the next easiest issue, and so on. Stop when you have one answer or you aren’t sure how to address the remaining differences. All errors for each choice are detailed in the next section.
(4) Eliminate (and Repeat)
(A) CORRECT. The modifier in the coming years correctly modifies the clause that follows (it is going to be improved), describing when the model is going to be improved.
(B) This sentence says that the statisticians will improve the model. The word by indicates that what follows is the way in which they will improve the model—perhaps the statisticians will tweak the algorithm or run more simulations. Instead, the sentence continues, by enabling it to accurately forecast the results of the next election. Enabling the model to accurately forecast the election is the consequence, not the cause, of the improved model.
(C) This answer may sound very tempting; the only difference between this choice and the correct answer is the placement of the modifier in the coming years. Here, in the coming years is placed next to the election. But a single election does not take place over a time period lasting years; had the sentence instead said elections, the modifier placement would be acceptable.
(D) The modifier in the coming years is placed next to the results, implying that the model is going to forecast the election results over a period of years. But the forecast will take place at a particular moment. In the coming years should modify it is going to be improved; the process of improving the model is what will take years.
(E) This answer repeats the modifier mistake from answer (C): in the coming years is placed next to the election. But a single election does not take place over a time period lasting years; had the sentence instead said elections, the modifier placement would be acceptable.
