Different situations have always called for different types of attention: compare driving to reading a book, both of which require very specific types of attention. The modern default calls for fast attention switching. (src)
Could you introduce to me some synonyms for the "default" here? Does it mean something like The modern life calls for fast attention switching?
Is there any rule in English about using the same verb in two consequent sentences? Here are "called for" and "calls for". Is it ok? What synonyms might replace the verb "call for" here?
