Hello Fellow Teachers,
I have a little problem that I would like to find an answer to.
Below are several sentences that maybe simplify the problem.
Which sentence is wrong?
#1 When Barry moved to Alsaka, he was ten.
#2 When Barry moved to Alaska he was ten.
#3 Unfortunately, he had already left his office when she arrived.
#4 Unfortunately, he had already left his office, when she arrived
#5 I like pineapple, pears and apples but not grapes.
#6 I like pineapple, pears, and apples, but not pears.
Let me know what you think
Sorry, I meant #2 is wrong not #1.
What is wrong with #5?
In your 5th example, you had commas in all the right places except one:
I like pineapple, pears and apples, but not grapes.
