Read the given sentence to find out whether there is any error in any part and indicate your response.
The police are working hard (A) until they are able to (B) arrest the culprits. (C) No error (D)

Correct option is B

· The error in the sentence is found in part (B), specifically with the use of the conjunction "until."
· The phrase "until they are able to" suggests a future condition that is not yet met and will continue indefinitely until that condition is fulfilled. However, this doesn't logically fit with the phrase "The police are working hard," which describes ongoing action.
· The correct conjunction should imply that the police continue to work hard for the current objective without suggesting that their effort is yet to start or is conditional upon being able to eventually arrest the culprits.
Correction:
· The phrase could be better structured as "The police are working hard to arrest the culprits," or if intending to use a similar structure with "until," the sentence should be reframed to fit the temporal context appropriately, such as, "The police will continue to work hard until they arrest the culprits."
Grammatical Rule:
· Conjunctions like "until" should be used to link actions in a way that accurately reflects the temporal relationship between them. In the original sentence, "until" introduces a future condition inappropriately linked with an ongoing present action, causing a temporal misalignment. Using "to" or restructuring the sentence to align with future intent can resolve this inconsistency.
