If the needle on an industrial sewing machine becomes badly worn, the article being sewn can be ruined. In traditional apparel factories, the people who operate the sewing machines monitor the needles and replace those that begin to wear out. Industrial sewing operations are becoming increasingly automated, however, and it would be inefficient for a factory to hire people for the sole purpose of monitoring needles. Ttherefore a sophisticated new acoustic device that detects wear in sewing machine needles is expected to become standard equipment in the automated apparel factories of the future. Which one of the following is most strongly supported by the information above? ['The needles of industrial sewing machines wear out at unpredictable rates.', 'Traditional apparel factories do not use any automated equipment.', 'In the automated apparel factories of the future, each employee will perform only one type of task.', 'In automated apparel factories, items will be ruined by faulty needles less frequently than happens in traditional apparel factories.']
