Read the Original Sentence Carefully, Looking for Errors:
On initial reading, this sentence appears to contain a series of results of the variables: "will influence the tempo ..., reduce inequalities ...." However, the series is not completed. In fact, the intent of the sentence is that influencing the tempo of economic growth will have the further effect of reducing inequalities among two groups of people. "Reduce" should be replaced with "reducing" to make the part of the sentence after the comma into a modifying phrase.
This sentence also tests knowledge of the use of who verus that. In general, use who (as well as whom) to refer to people and use that (and which) to refer to things.
Scan and Group the Answer Choices:
Each answer choice provides an alternative form of reduce. There is, however, a 3-2 split at the end of the choices between "that" in (C) and (E) and "who" in (A), (B), and (D). In this sentence, the antecedent is “people” (not “employment”), clearly requiring the use of “who.”
Eliminate Wrong Answer Choices:
(A) uses the incorrect "reduce," implying a series of actions beginning with "influence."
(C) and (E) are wrong because they use "that." (E) may also be eliminated because it begins with the awkward phrase "for the reduction of." (C) may also be eliminated because the use of "to reduce" after the comma suggests that a list is in progress: "to control . . ., to reduce . . . ." However, there is no third "to" item to complete the list. The use of the infinitive also subtly changes the meaning of the sentence, implying that the reason for the control of the variables is the reduction of inequalities.
(D) includes the awkward and unnecessary "for" before "reducing." There's no need to use both a conjunction and a participle verb.
(B) correctly uses "reducing" and "who" and does not introduce any other errors. Note that the repetition at the end of the underlined portion of "who" is a little grating stylistically, but it is not wrong. Since all other choices have errors, (B) is the winner.
TAKEAWAY: Longer sentences can have multiple errors. Choose any one error to start eliminating choices instead of reading for all possible errors at once.
Sorry but I don't understand: In b reducing (present participle after comma) should refer to the subject of the preceding clause "variables" but the ownership is reducing and not the variables. Please explain!.
