<h3>
Answer: No, it is not a run-on sentence</h3>
This is one full thought that doesn't run on for too long. The "overcome with joy" portion is the dependent clause that needs the other part "Mrs. Monroe told her husband the exciting news about her promotion" which is the independent clause. The independent clause could be its own sentence without the dependent clause, but not the other way around.
This requires a great deal of planning. You must first start with what you MOST want to highlight, making sure you hit all of the requirements. Each highlighted part should be its own box. From there, add a detail to each along with the commentary. Then time it. If you go over, see what you can possibly eliminate. If it isn’t long enough, add more detail where you can. Make sure that is is well-organized from start to finish. This will require trial and error, but proper planning will help.
