Exam
Answer
The correct answer is (A) “essential.” This sentence requires an adjective to describe the noun “carbon emissions.” The word “essential” means “absolutely necessary,” which fits the context of the sentence, indicating that reducing carbon emissions is crucial to slowing down global warming.
Let’s break down why the other options are incorrect:
(B) “Essentials” is a noun that means “things that are absolutely necessary.” However, in this sentence, we need an adjective, not a noun.
(C) “Essentially” is an adverb that means “in essence; at bottom or by one’s (or its) very nature.” While it could seem like a possible answer, it does not fit grammatically in the sentence as an adverb cannot describe a noun.
(D) “Essence” is a noun that means “the intrinsic nature or indispensable quality of something.” Like “essentials,” it cannot be used to describe “carbon emissions” in this sentence because it is not an adjective.

This question tests knowledge of vocabulary and understanding of how different forms of a word (noun, adjective, adverb) fit into a sentence. The explanation is provided in simple language to make it accessible for intermediate level of learners, ensuring they understand the reasoning behind the correct answer and why the other options do not fit.
