probably not a direct rendering of speech, but was
more likely to begin as a separate and distinct
symbolic system of communication, and only later
merged with spoken language.

(A) was more likely to begin as
(B) more than likely began as
(C) more than likely beginning from
(D) it was more than likely begun from
Use of the pronoun it makes this
construction a main clause, in which case
the comma after communication must be
omitted and began must be used to be
parallel to merged
(E) it was more likely that it began
the second it acts as the subject of the
subordinate clause, and this usage requires
the omission of the comma after communication
