Identify the incorrect punctuated sentence.
A. Remember to turn off the light and lock the door.
B. On our trip we will be driving, and taking the train.
C. Fred will feed the cat, and Rose will pick up the mail.
D. The weekend was short but fun.
B. On our trip we will be driving, and taking the train.
The incorrect punctuation here is the comma before "and taking the train." Generally, when you have a compound predicate (two verbs that share the same subject), you do not need a comma to separate the two parts. The corrected sentence should be:
"On our trip we will be driving and taking the train."
