Hi everybody!
I found this problem slightly hard for me.
Few days ago I solved wrong this SC question (from 1000 Real SC quesyions):
During the Great Depression, industrial output fell by nearly fifty percent from its peak in 1929 down to its nadir in 1933.
(A) During the Great Depression, industrial output fell by nearly fifty percent from its peak in 1929 down to its nadir in 1933.
(B) During the Great Depression, industrial output fell by nearly fifty percent from its peak in 1929 to its nadir in 1933.
(C) At the time of the Great Depression, industrial output fell by almost fifty percent from its 1929 peak down to its 1933 nadir.
(D) At the time of the Great Depression, industrial output fell from its peak in 1929, by nearly fifty percent, to it nadir in 1933.
(E) During the Great Depression, industrial output fell from its peak in 1929 to its nadir in 1933 by nearly fifty percent.
OA is B, but I don't understand the difference between "during" and "at the time of", because in my language both those phrases mean the same.
Please! Some native speaker! I need help
