Journalists sometimes use historical photographs to illustrate articles about current events. But this recycling of old photographs overstates the similarities between past and present, and thereby denies the individual significance of those current events. Hence, the use of historical photographs in this manner by journalists distorts public understanding of the present by presenting current events as mere repetitions of historical incidents. Which one of the following, if assumed, enables the conclusion of the argument to be properly inferred? ['If journalists believe current events to be mere repetitions of historical incidents, then public understanding of the present will be distorted.', 'If a journalistic practice distorts public understanding of the present by overstating the similarities between past and present, then it denies the individual significance of any articles about current events.', 'Any practice by which journalists present current events as mere repetitions of historical incidents overstates the similarities between past and present.', 'If the work of a journalist overstates the similarities between past and present, then it distorts public understanding of the present by presenting current events as mere repetitions of historical incidents.']
