Science writer: All scientists have beliefs and values that might slant their interpretations of the data from which they draw their conclusions. However, serious scientific papers are carefully reviewed by many other scientists before publication. These reviewers are likely to notice and object to biases that they do not share. Thus, any slanted interpretations of scientific data will generally have been removed before publication. Which one of the following is an assumption required by the science writer's argument? ['Biases that are present in published scientific papers and shared by most scientists, including those who review the papers, are unlikely to impair the scientific value of those papers.', 'The interpretation of data is the only part of a serious scientific paper that is sometimes slanted by the beliefs and values of scientists.', 'The scientists reviewing serious scientific papers for publication do not always have biases likely to slant their interpretations of the data in those papers.', 'In general, biases that slant interpretations of data in serious scientific papers being reviewed for publication are not shared among all scientists.']
