In the question below, a paragraph is split into several parts. Examine each part for grammatical accuracy and select the option that correctly identifies which parts are grammatically correct or incorrect.

(A) Climate change have become a pressing issue across the world. Scientists (B) warns that if emissions keep rising, heatwaves will intensify. Rising sea levels threaten coastal cities, displacing communities (C) and damaging infrastructure. Simple actions, like reducing energy waste and using public transport, can make a meaningful difference. (D) Governments and businesses must invest in clean technologies (E) while supporting workers through a just transition.

The correct option is C, D and E are correct.

Let us analyze each part of the given paragraph for grammatical accuracy:

Part (A): "Climate change have become a pressing issue across the world. Scientists"
• Analysis: The subject "Climate change" is singular. Therefore, it requires the singular auxiliary verb "has" instead of the plural "have".
• Correction: "Climate change has become a pressing issue..."
• Status: Incorrect

Part (B): "warns that if emissions keep rising, heatwaves will intensify. Rising sea levels threaten coastal cities, displacing communities"
• Analysis: The subject "Scientists" (from the end of part A) is plural. Therefore, it requires the plural verb "warn" instead of the singular verb "warns".
• Correction: "Scientists warn that if emissions keep rising..."
• Status: Incorrect

Part (C): "and damaging infrastructure. Simple actions, like reducing energy waste and using public transport, can make a meaningful difference."
• Analysis: This part contains correct parallel structure ("reducing", "using") and proper subject-verb agreement with no grammatical errors.
• Status: Correct

Part (D): "Governments and businesses must invest in clean technologies"
• Analysis: The subject "Governments and businesses" correctly agrees with the modal verb "must invest" with appropriate prepositional phrasing.
• Status: Correct

Part (E): "while supporting workers through a just transition."
• Analysis: This participial phrase is grammatically complete, concise, and correctly connected to the main clause.
• Status: Correct

Conclusion:
Parts (A) and (B) contain subject-verb agreement errors, whereas parts (C), (D), and (E) are completely free of errors. Hence, C, D and E are correct.
