Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. brought.
Context: The sentence describes the effects that global warming has already caused. Since the action refers to changes that have already happened, the past tense is required.
Meaning of the words:
Bring: base form of the verb, not suitable here.
Brings: present tense, does not match the past action indicated by “has.”
Brought: past participle form of “bring,” correct with “has” in present perfect tense.
Bringing: present participle, not grammatically correct in this construction.
Correct word: Brought
Reason: The verb must agree with “has” in the present perfect tense: “has brought profound changes.” Other forms are grammatically incorrect here.
Final Sentence: Global warming, a phenomenon primarily caused by human activities, has brought profound changes in weather patterns worldwide.
Hence, the chosen option is correct.
