Psychologist: Satisfaction and happiness with one' s family cannot exist unless families have established strong values of mutual trust, love, and respect. Such bonds are formed and strengthened only through making these key values the basis for all actions within the family. It is obvious then that widespread reliance on movies and electronic media for entertainment has an inherently corrosive effect on one' s family life. Which one of the following is an assumption on which the psychiatrist's argument depends? ['Families cannot usefully increase their happiness by using electronic media.', 'People who rely on movies and electronic media for entertainment are generally not as happy with their families as those who do not.', 'People who rely on movies and electronic information for entertainment are unable to form strong values of trust, love, and respect with their families.', 'Newspapers and other forms of print media strengthen, rather than weaken, family values.']
