The ups and downs of life may seem to have no predictable plan. But scientists now know there are very definite patterns that almost all people share. Even if you’’ve passed some of your "prime", you still have other prime years to experience in the future. When are you smartest From 18 to 25, according to I. Q. scores; but you’’re wiser and more experienced with increasing age. You’’re sharpest in your 20’’s. But your I. Q. for other tasks climbs. Your vocabulary at age 45, for example, is three times as great as when you graduated from college. At 60, your brain possesses almost four times as much information as it did at age 21. When are you happiest You have the best physical sense of yourself from 15 to 24; the best professional sense from 40 to 44. Before age 24, we believe that our happiest years are yet to come; over 30, we believe that they’’re behind us. A National Health Survey agrees: After age 30, we become more realistic and do not view happiness as a goal in itself. If we maintain our health, achieve professional and emotional goals, happiness will follow. When are you most creative Generally between 30 and 39, but the peak varies with different professions. Mozart wrote a symphony by age eight, and Mendelssohn composed his best known work at 17, but most of the great music was written by men between 33 and 44. Though the peak in most fields comes early, creative people continue to produce quality work throughout their lives. For the "well-conditioned mind" , there is no upper limit. The expression "prime years" on Line 2, Paragraph 1 probably means_________.

A. the age of ideal physical condition
B. be early in time or order
C. the period of ideal or peak condition
D. the most special days

You should present your most attractive qualities throughout the interview.
