"used" here is not a past-tense verb -- it's a past participle (which functions as an adjective). such participles don't have tenses; they adapt to the tense of the clause to which they are attached.
therefore, there is no "change" in the tense, because there are no other verbs in the sentence besides was/has been.
given this context, basically *any* tense would be fine.
was --> the talk is over.
has been --> the talk is ongoing, and the sentence describes the part that has so far been given.
is (not in the choices, but workable) --> general discussion of the talk (perhaps from its authors).
E does not sound right because predominance is a "quality" and we are dealing with "some kind of quantity - countable/uncountable"
not sure what you mean here, but you're correct that "predominance" is wrong. (the easiest way to find out more about "predominance" is to consult a dictionary.)
A - Majority of TALKS and not TALK (I am not sure on this but I have never seen a singular objects used with Majority. Eg. Majority of students ARE (plural usage) , while for singular usage --> In the election, the Majority HAS the power).
it's true that "majority" is used with plurals in the majority of instances (heh), but it can also be used with singular / uncountable quantities.
in fact, the OG itself uses it in this way at times. e.g., see p. 37 of OG12, problem 29, in which "the majority of the coal" is mentioned.
Ron has been teaching various standardized tests for 20 years.
