(11) “Trust me” says Jack’s owner.

Answer:
Insert a comma after me
Explanation:
well, it's not Change Jack's into Jacks' unless there are a lot of Jacks.
And it's not Insert quotation marks after period, unless someone says "'Trust me,' says Jack's owner.
And changes do need to be made after in the sentence.
