i fail to understand as why choice A is so wrong
choice A:the economic strengthening of the south with improvement of soil and diversification of corps
can you please explain as why preposition "with" is wrong here ?
If "with ____" is used to modify some goal, "____" is normally a tool used to achieve that goal"”i.e., not the methodology through which the goal is achieved.
For the methodology, you'd use through instead, as is done here.
E.g., you can gain strength through weightlifting. Or you can gain strength with dumbbells.
