Correct option is E

Correct Answer: E – No rearrangement needed

Correct Sentence:
The proliferation of technology over the last 100 years has happened so quickly and caused many societal changes.

Sentence Structure Analysis:

·       A. the proliferation of technology → Subject

·       B. over the last 100 years has → Time phrase + auxiliary verb

·       C. happened so quickly and → First verb phrase

·       D. caused many societal changes → Second verb phrase (parallel structure)

Grammatical Rule:

·       The sentence follows correct Subject + Verb (perfect tense) + Parallel actions structure.

·       “has happened” and “(has) caused” maintain parallelism (second “has” is understood).
