Idiom + Verb form
This sentence is a comparison in which probably not x is balanced by but more than likely y.When more is used in the comparative form of an adjective (more difficult) or adverb (more likely),it is followed by than.The words used to show the comparison between x and y,but more than likely,must also introduce the correct verb form,allowing y to fit grammatically into the rest of the sentence.The subject of the sentence has three verbs,all of which should be parallel:the earliest writing was...began...merged.Was...to begin is not parallel and results in a construction that is not grammatically correct.
A In this context,more likely is not a complete idiomatic expression;was...to begin is not parallel to was and merged.
B Correct.In this sentence,more than likely is the correct comparative construction,the simple past tense began,parallel to was and merged,fits grammatically into the sentence.
C Subject should be followed by three verbs; beginning from is not a verb.
D Use of the pronoun it makes this construction a main cluase,in which case the comma after communication must be omitted and began must be used to be parallel to merged; was...begun is not he correct tense.
E In this awkward,unclear,and wordy construction,the first it must be followed by is,not was,because the theory is current; the second it acts as the subject of the subordinate clause,and this usage requires the omission of the comma after communication.
The correct answer is B.
