Meaning is crucial to solving this problem:Understanding the intended meaning is key to solving this question; the intended core meaning of this sentence is that in every election since 1968, the number of women serving in state legislatures has grown.
Concepts tested here: Subject-Verb Agreement + Tenses + Awkwardness/Redundancy• The present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present.
• The present perfect continuous tense (marked by "has/have been") is the correct tense to refer to actions that started in past and continue into the present.
A: Correct.1/ This answer choice correctly refers to the singular noun phrase "number of women" with the singular verb "has grown".
2/ Option A uses the construction "number of women...has grown", conveying the intended meaning - that in every election since 1968, the number of women serving in state legislatures has grown.
3/ Option A correctly uses the present perfect tense verb "has grown" to refer to an action that concluded in the past but continues to affect the present.
4/ Option A is free of any awkwardness or redundancy.
B:1/ This answer choice incorrectly refers to the singular noun phrase "number of women" with the plural verbs "are" and "have grown".
2/ Option B uses the needlessly wordy phrase "who are in state legislatures", leading to awkwardness and redundancy.
C:1/ This answer choice uses the passive and needlessly wordy construction "there has been growth in", leading to awkwardness and redundancy.
D:1/ This answer choice alters the meaning of the sentence through the phrase "have been in state legislatures"; the construction of this phrase leads to an incoherent meaning; the intended meaning is that in every election since 1968, the number of women serving in state legislatures has grown.
E:1/ This answer choice incorrectly uses the present perfect continuous tense verb "have been growing" to refer to an action that concluded in the past but continues to affect the present; please remember, present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present, and the present perfect continuous tense (marked by "has/have been") is the correct tense to refer to actions that started in past and continue into the present.
2/ Option E uses the passive and needlessly wordy construction "women have been growing in number", leading to awkwardness and redundancy.
