Understanding Grammatical Errors in Sentences
The question asks us to identify the segment in the given sentence that contains a grammatical error. The sentence is: "Climate change are a greatest threat facing our planet which needs our immediate attention."
Let's break down the sentence and examine each part:
- "Climate change": This is the subject of the sentence. While "change" can be countable, "climate change" as a phenomenon is typically treated as a singular noun phrase.
- "are": This is the verb following the subject "Climate change". If "Climate change" is singular, the verb should be singular. The singular form of "are" is "is".
- "a greatest threat": "greatest" is a superlative adjective (comparing climate change to all other threats). Superlative adjectives are typically preceded by the definite article "the", not the indefinite article "a". So, it should be "the greatest threat".
- "facing our planet": This is a participial phrase modifying "threat". It is grammatically correct.
- "which needs our immediate attention": This is a relative clause modifying the preceding noun (either "planet" or more likely "threat"). The verb "needs" agrees with a singular antecedent ("threat"). This part is grammatically correct.
Combining the observations, the segment containing the errors is where the incorrect plural verb "are" is used with the singular subject "Climate change", and where the incorrect article "a" is used before the superlative "greatest". This combined segment is "are a greatest".
Detailed Analysis of the Incorrect Segment: "are a greatest"
The segment "are a greatest" contains two distinct errors:
- Subject-Verb Agreement Error: The subject is "Climate change", which is a singular concept. The verb used is "are", which is plural. The verb should agree in number with the subject. The correct verb should be "is".
- Article Usage Error: "greatest" is the superlative form of the adjective "great". When using a superlative to refer to a unique or paramount example within a group, the definite article "the" is used before the superlative adjective. The indefinite article "a" is incorrect here. The correct phrase should be "the greatest".
Therefore, the segment "are a greatest" should correctly be "is the greatest".
Evaluation of Other Options
- "which needs": This is part of a relative clause modifying "threat" (singular). The verb "needs" is singular and correctly agrees with a singular antecedent. This segment is correct.
- "our immediate attention": This is the object of the verb "needs". The phrase is grammatically sound. This segment is correct.
- "facing our planet": This is a participial phrase acting as an adjective modifying "threat". It correctly describes the threat's action. This segment is correct.
Based on this analysis, the segment "are a greatest" is the one that contains grammatical errors.
| Sentence Segment | Analysis | Grammatical Status |
|---|---|---|
| Climate change | Singular subject | Correct |
| are | Plural verb used with singular subject | Incorrect (Error 1) |
| a | Indefinite article used before superlative | Incorrect (Error 2) |
| greatest | Superlative adjective | Correct in form, but incorrect article used |
| threat | Noun | Correct |

| which needs | Relative clause, verb agrees with singular antecedent | Correct |
| our immediate attention | Noun phrase, object of "needs" | Correct |
Revision Table: Key Grammar Concepts
| Concept | Explanation | Example |
|---|---|---|
| Subject-Verb Agreement | A singular subject takes a singular verb. A plural subject takes a plural verb. "Climate change" is treated as singular. | Incorrect: Climate change are... Correct: Climate change is... |
| Articles with Superlatives | The definite article "the" is typically used before a superlative adjective when referring to a specific item that is the most extreme in a group. | Incorrect: ...a greatest threat... Correct: ...the greatest threat... |
Additional Information: Climate Change and Grammar
Understanding sentence structure and grammar is crucial for effective communication, especially when discussing important global issues like climate change. Correct subject-verb agreement ensures clarity about what the sentence is describing. Proper use of articles helps specify whether you are referring to one of many or the single most significant item.
Climate change is a complex phenomenon with far-reaching impacts. Accurately describing it requires precise language. Grammatical correctness helps convey the seriousness of "the greatest threat" clearly and unambiguously.
