By confronting a devastated economy through actions such as creating the Federal Deposit Insurance Corporation, opening the Securities and Exchange Commission, suspending the gold standard, launching massive public works programs, and improving the morale of a demoralized nation through his fireside chats, First Inaugural address, and other motivational speeches, Franklin Roosevelt both lifted the spirits of Americans across the country and set the United States on a course that helped propel it out of the Great Depression.
A) launching massive public works programs, and improving the morale of a demoralized nation through his fireside chats
B) and launching massive public works programs, and improving the morale of a demoralized nation through his fireside chats
C) and launching massive public works programs, and by improving the morale of a nation demoralized through his fireside chats
D) and through the launch of massive public works programs, and by improving the morale of a demoralized nation through his fireside chats
E) and launching massive public works programs, and by improving the morale of a demoralized nation through his fireside chats
My answer was A, while the correct answer is E. The explanation goes as folows-
Franklin Roosevelt did two things to set the United States on a course to propel itself out of the depression: (1) confronting a devastated economy (2) improving the morale of the demoralized country. Both these two actions and the list of steps taken to accomplish them need to be parallel. Since the first action (followed with its list of steps) is introduced with by the second action (followed with its list of steps) should also be introduced with by.
My doubt is- why can't i consider that roosevelt did 4 seperate actions to confront the bad economy? how do i understand from a statement that has been parallelly constructed, like in the above case, that roosevelt has done 2 completely different actions ( 1 and 2)?
