Regional Manager: Several of our stores have recently implemented a new method of taking daily inventory that uses less of our warehouse employees’ time by using more automated processes than the previous system. It is thus clear that the new, more automated system better optimizes these stores’ use of human resources than the older method did.
Which of the following, if true, most strengthens the argument above?
【选项】
The warehouse employees who use the more automated system are employed for more hours than those at other stores because their warehouses are larger than the others.
