read the sentence. unaware of the change in the weeks work schedule, the loyal customers saw marquis arrive…

Brief Explanations:

The original sentence has a dangling modifier. "Unaware of the change in the week's work - schedule" seems to modify the customers instead of Marquis. To correct it, we should re - structure the sentence so that the modifier clearly refers to Marquis.

Answer:

Marquis, unaware of the change in the week's work schedule, arrived to work a day early, much to the surprise of the loyal customers.
