.Identify the error in the given sentence and supply the correction :The orchestra performed on the central theatre in front of a huge audience.

The error in the sentence is the preposition used. The phrase "on the central theatre" is incorrect because "on" typically refers to a surface or a position above something. In this context, the correct preposition should be "in," as it denotes being inside a location. Therefore, the corrected sentence should read:

"The orchestra performed in the central theatre in front of a huge audience."

This correction improves the clarity and grammatical accuracy of the sentence by appropriately indicating the location of the performance. The use of "in" conveys that the orchestra was physically situated within the theatre, which aligns with common usage in English when referring to events held at specific venues.
