Answer:
Step-by-step explanation:
Unless this question was written in 1913, there really is no answer. I say that because the best answer is B, but it doesn't really happen. If it did, though trees can be replanted where other trees were cut to use for machinery, the question really makes no sense.
I don't know if you live in the country or not. I do. Combines can cost a million dollars or so. They run on ordinary gasoline that has a dye put in it. It's called purple gas. Ordinary folks can't use this stuff in their vehicles. One get's fined for doing it.
In Canada (where I live), fall is not very long. You have roughly a month (September) to get the crops off, and if it rains, you don't have the full month -- and it often does. It would be absurd to cut timber to use in these 35 foot tall machines.
The only other possible answer is D, but it all depends on what material the packaging material is. The word recycling has to be in D to make it a viable answer.
