Where is the punctuation error in the following sentence? After turning off the water,

(1) pulling the shades,

(2) and locking the doors

(3) they went on their vacation.

(4). 1. 2. 3. 4

The correct answer is 3.

In the sentence, there should be a semicolon after the word "door." So the sentence should be like this: After turning off the water, pulling the shades, and locking the doors; they went on their vacation.
