Answer to Question 1

Answer: B

Answer to Question 2

Answer: Men and women who are single tend to have higher testosterone levels than those who have partners, perhaps because high testosterone levels helps people initiate sexual relationships. Among men high testosterone levels are consistently correlated with the initiation of sexual activity, but some evidence suggest that this hormone also influences women's sexual behavior, too. Another study found that men's testosterone levels increase prior to divorce and then decrease when they remarry.
