Which of the following shows methods of harvesting corn in order from the highest rate of resource consumption to the lowest? a. hand-picked and sorted by a simple machine picked and sorted by hand picked and sorted by complex machinery b. picked and sorted by complex machinery picked and sorted by hand hand-picked and sorted by a simple machine c. picked and sorted by complex machinery hand-picked and sorted by a simple machine picked and sorted by hand d. picked and sorted by hand hand-picked and sorted by a simple machine picked and sorted by complex machinery

The correct answer is option C, Picked and sorted by complex machinery hand-picked and sorted by a simple machine picked and sorted by hand

Complex machinery need following resources to operate – fuel, another machine to transport them to the site. High maintenance, electricity , resource for cleaning  the machinery after use and the human resource to operate it

Simple machinery need following resources – fuel , maintenance, and the human resource to operate it

While if someone uses hand to work then in this case the only resource in usage is the human resource.  

Thus it is clear that the maximum resources are used when the complex machine is used for harvesting corn while the least resources are used if harvesting is done manually by hand.
