Grammar Rule: Double Negation
A sentence should not contain two negatives when expressing a single negative idea.
Here:
- “couldn’t identify” = negative
- “no flaws” = another negative
This creates a double negative, which is incorrect in standard English.
Correction:
- couldn’t identify any flaws
or - could identify no flaws
Part (D): “making it a remarkable success”
Correct participial phrase.
Correct Sentence:
Despite the team's efforts to find flaws, they couldn't identify any flaws in the project, making it a remarkable success.
