Question 283

  • ○

  • ○

  • ○

    presumes, without providing justification, that if one does not hold oneself in sufficient self-esteem one cannot be useful or needed

Question 285

A smoker trying to quit is more likely to succeed if his or her doctor greatly exaggerates the dangers of smoking. Similar strategies can be used to break other habits.
