Quizplus · Accepted Answer

Increasing the number of backhoes given to a construction crew would increase the amount of capital available per worker, thus increasing the capital-to-labor ratio. Replacing the roof on a factory building may improve technology or safety but doesn't necessarily increase the capital-to-labor ratio. Sending workers to training classes may improve their productivity and efficiency but doesn't change the amount of capital available per worker. Increasing the number of workers harvesting crops in a field would decrease the capital-to-labor ratio, as there would be less capital available per worker.
