The introduction of automatic elevator equipment allowed firms to handle the movement of people in a multistory building at less cost, thus decreasing the demand for elevator operators. the best explanation for this change is that the multiple choice marginal product of elevator operators was equal to its price. marginal product of automatic elevator equipment was equal to its price. marginal product of automatic elevator equipment divided by its price was greater than that for elevator operators. marginal product of elevator operators divided by its price was greater than that for automatic elevator equipment.

you can lose ranking 2 ways.

1) you don't have enough points due to you expending them by asking questions/your answers are deleted.

2) your brainliest's expired. this means that brainliests, once they exceed the 30 day limit, expires. this is to ensure that you continue to contribute into the community at a constant rank if you want to continue to have/exceed the rank you have right now.

if you go to profile, and click "show more information" located on the bottom left of the box with your information (on top of the questions answered, questions asked, and friends), you will be given the following information (example):

member since : 02/13/2017, 18: 11

questions answered: 9741

questions asked: 162

no. of brainliest answers: 1575

brainliest answers in last 30 days: 10

warnings: 0 view

questions/answers reported: 2637

questions/answers incorrectly reported: 64

look at the "brainliest answers in the last 30 days". this is the one that will affect your rank other than your points. again, once your brainliest expires (was earned 31+ days ago), it will not be counted.
