Spot the error:Provided by she was paid overtime, Kara agreed to clean the gold course before she left for the day.

Explanation

The phrase "Provided by" should be replaced with "Provided that" to make the sentence grammatically correct. The correct sentence would be:"Provided that she was paid overtime, Kara agreed to clean the golf course before she left for the day.""Provided that" is a subordinating conjunction that introduces a condition, whereas "Provided by" is not a correct idiomatic expression.In summary, the correct answer is A) Provided by, which should be replaced with "Provided that" to make the sentence grammatically correct.
