<human>:  A swarm of ants discovered a pile of sugar that spilled from a dropped bag. They begin to harvest it and carry it off to their anthill. Every hour, the ants remove 4 ounces of sugar. The bag of sugar held 24 ounces before it was dropped. After three hours, how many more hours will the ants need to harvest the remaining sugar?
<bot>: How many ounces of sugar have the ants removed after 3 hours? ** After 3 hours, the ants have removed 4 * 3 = <<4*3=12>>12 ounces of sugar.
How many ounces of sugar are left? ** There are 24 - 12 = <<24-12=12>>12 ounces of sugar left.
How many more hours will the ants need to harvest the remaining sugar? ** Thus, the ants need 12 / 4 = <<12/4=3>>3 more hours to harvest the remaining sugar.
