Concepts tested here: Comparison + Akwardness/Redundancy• “like” is used for comparing nouns, “as” is used for comparing actions/clauses, and “such as” is used for giving examples.
A: This answer choice uses the redundant phrase "ancestors before them", rendering it awkward and needlessly wordy; this phrase is redundant, as "ancestors" are understood to be familial predecessors, meaning "before them" can be deleted without a loss of clarity.
B: This answer choice incorrectly uses "Like" to compare the verbs "did" and "follow"; please remember, “as” is used for comparing actions/clauses, and “like” is used for comparing nouns. Further, Option B uses the redundant phrase "ancestors...before them", rendering it awkward and needlessly wordy; this phrase is redundant, as "ancestors" are understood to be familial predecessors, meaning "before them" can be deleted without a loss of clarity.
C: This answer choice uses the redundant phrase "ancestors before them", rendering it awkward and needlessly wordy; this phrase is redundant, as "ancestors" are understood to be familial predecessors, meaning "before them" can be deleted without a loss of clarity.
D: Correct. This answer choice correctly uses "As" to compare the verbs "did" and "follow". Further, Option D is free of any awkwardness or redundancy.
E: This answer choice incorrectly uses "Like" to compare the verbs "did" and "follow"; please remember, “as” is used for comparing actions/clauses, and “like” is used for comparing nouns.
