Question

plastic bins have been rolled by the overhead door. piled on the other side of this room are several thousand steel rods of varying lengths. these rods are to be sorted by length and placed in the bins. please arrange rods according to the following criteria: bin 1 is for rods that are four to five meters long. bin 2 is for rods that have a length of over five meters, up to eight meters. bin 3 is for rods that have a length of over eight meters, up to ten meters. bin 4 is for rods that have a length of over ten meters. set apart any irregular or especially short or long rods. we cannot afford to have any rbs again. they frustrate the customer and lower our credibility. please ensure the accuracy of your measurements and that rods are placed into the requisite bins.further, be sure to measure any rods where it is not immediately evident to which bin they belong. you are tasked with sorting the rods. what does rb likely stand for? rejected bins requisite bins red bins rolling bins rod bins

Explanation:

The text mentions that irregular or especially short - long rods should be set apart to avoid 'RBs' which frustrate customers and lower credibility. Since the focus is on rods not being in the correct bins, 'Rejected Bins' makes the most sense as it implies bins that have rods that don't meet the sorting criteria.

Answer:

A. Rejected Bins
