Mr. Lawson: We should adopt a national family policy that includes legislation requiring employers to provide paid parental leave and establishing government-sponsored day care. Such laws would decrease the stress levels of employees who have responsibility for small children. Thus, such laws would lead to happier, better-adjusted families. Which of the following, if true, would most strengthen the conclusion above? (A) An employee’s high stress level can be a cause of unhappiness and poor adjustment for his or her family. (B) People who have responsibility for small children and who work outside the home have higher stress levels than those who do not. (C) The goal of a national family policy is to lower the stress levels of parents. (D) Any national family policy that is adopted would include legislation requiring employers to provide paid parental leave and establishing government-sponsored day care.（A）
