Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. promoted.
Context: The blank refers to AI and machine learning contributing to automation and efficiency in the past.
Meaning of the words:
promotes: Present tense; does not fit the past action context.
promoted: Past tense; correctly indicates that AI and machine learning contributed in the past.
promoting: Present participle; implies ongoing action, which is not intended here.
promote: Base form; grammatically incorrect here.
Correct word: promoted
Reason: The passage describes completed past contributions of AI and machine learning, so “promoted” is the appropriate past tense.
Final Sentence: Innovations in artificial intelligence and machine learning promoted automation and efficiency, transforming industries and creating new economic paradigms.
Hence, the chosen option will be correct.
