Question

Which sentence contains a nonrestrictive clause that is punctuated correctly? My boss—who was recently promoted again is great at motivating her employees. My boss, who was recently promoted again, is great at motivating her employees. My boss who was recently promoted again—is great at motivating her employees. My boss, who was recently promoted again is great at motivating, her employees.

Answer 1

The correct answer is My boss, who was recently promoted again, is great at motivating her employees. That is because it has an appositive phrase that is separated by commas properly. Dashes wouldn't be used here because they are used in different situations, not to separate apposition.
