I want to know the answer to the following question:
Which famous line from Kerry's speech was later featured in one of his later television ad campaigns?
All the background I'm provided with is that "He later delivered what may have been the speech's most memorable line when he said, "the future doesn't belong to fear, it belongs to freedom", a quote that later appeared in a Kerry/Edwards television advertisement.". Is that enough to answer the question?
Answer: yes
