A) there will be 4 million more tractors than at the beginning of the year.
B) the production possibilities curve will shift outward.
C) there will be 4 million fewer tractors than at the beginning of the year.
D) there will be the same number of tractors as at the beginning of the year.
E) output cannot be determined due to insufficient information.

Since 4 million tractors wear out each year and the scenario does not mention the production of any new tractors, choosing point A (which does not specify tractor production) implies that no new tractors are added to replace the worn-out ones. Therefore, the number of tractors remains the same at the end of the year, assuming all worn-out tractors are replaced exactly, maintaining the tractor count.
