I have a trouble with parsing this question, does anyone have an idea?
Lol, I suspect that you are trying to be sarcastic but no evidence has been found.
Bug book niceee.
Read it like this:
If ______ increase are not also necessary in energy ,labor and other inputs of crop production then it is almost desirable to increase yield of crop.
So, we want to increase yield of crop while not increasing the rest of the things .Hence, we don’t want to increase them equally.
Then the blank that matches with this idea : B. commensurate
Lol I did not realize that, it was a typo
Got it, thanks!
