Psychologist: Psychotherapists who attempt to provide psychotherapy on radio or television talk shows are expected to do so in ways that entertain a broad audience. However, satisfying this demand is nearly always incompatible with providing high-quality psychological help. For this reason, psychotherapists should never provide psychotherapy on talk shows. Which one of the following principles must be assumed in order for the psychologist's conclusion to be properly drawn? ['Psychotherapists should never attempt to provide psychological help in a manner that makes it unlikely to be of high quality.', 'Most members of radio and television talk show audiences are seeking entertainment rather than high-quality psychological help.', 'Psychotherapy should never be provided in a context in which there is any chance that the therapy might be of less than high quality.', 'It is never appropriate for psychotherapists to attempt to entertain a broad audience.']
