单选题The newspaper must provide for the reader the facts, unalloyed, unstated, objectively selected fact. But in these days of complex news it must provide more; it must supply interpretation, the meaning of the facts. This is the most important assignment confronting American journalism—to make clear to the reader the problems of the day, to make international news as understandable as community news, to recognize that there is no longer any such thing as " local" news because any event in the international area has a local reaction in manpower draft, in economic strain, in terms, indeed, of our very way of life. There is in journalism a widespread view that when you embark on (着手) interpretation, you are entering choppy(波浪起伏的) and dangerous waters, the swirling tides of opinion. This is nonsense. The opponents of interpretation insist that the writer and the editor shall confine himself to the "facts". This insistence raises two questions: What are the facts? Are the bare facts enough? As to the first query(疑问) consider how a so-called "factual" story comes about. The reporter collects, say, fifty facts; out of these fifty, his space allotment being necessarily restricted, he selects the ten which he considers most important. This is Judgment Number One. Then he or his editor decides which of these ten facts shall constitute the lead of the piece. (This is an important decision because many readers do not proceed beyond the first paragraph.) This is Judgment Number Two. Then the night editor determines whether the article shall be presented on page one, where it has a large impact, or on page twenty-four, where it has little. Judgment Number Three. Thus, in the presentation of a so-called "factual" or "objective" story, at least three judgments are involved. And they are judgments not at all unlike those involved in interpretation, in which reporter and editor, calling upon their research resources, their general background, and their "news neutralist," arrive at a conclusion as to the significance of the news. The two areas of judgment, presentation of the news and its interpretation, are both objective processes—as objective, that is, as any human being can be. The author is implying that______.
