Which of the following additional sentences would work BEST at the end of this passage if it were an advertisement for a school or college?

The correct answer is an accurate call to action for an advertisement that a school is running. Answer choice "Mozart didn’t wait; you shouldn’t either." might be tempting, but it would work fine with the passage as it is now and offers nothing new that relates to an advertisement for a school or college. Answer choices "The world needs more doctors, so you should start trying to be a doctor today." and "No matter what you want in life, you need schooling." would be less effective than the correct answer because they are too specific and not specific enough, respectively.
