Question

from the dark game: true spy stories from invisible ink to cia moles
by paul b. janeczko
when the first shot of the civil war was fired at four thirty in the morning on april 12, 1861, many believed that it would be a short conflict. even though fort sumter had to endure thirty - four hours of confederate bombardment before the union surrendered it, the union enjoyed a number of significant advantages over the confederacy. yet, by the time robert e lee surrendered to ulysses grant at appomattox, virginia, some four years later, about 620,000 soldiers had died on the battlefields, more than american battle deaths in all other wars from the revolution through the vietnam war
most of the war was fought in states south of washington, d.c., so southerners saw the union army as an invading force. for the union soldiers, this meant they had to fight in unfamiliar and hostile territory. this matter of geography affected the spies who worked behind enemy lines. northern spies could not often count on much hospitality from southerners. on the other hand, since so much of the war was fought in the south, confederate spies could usually find a safe house, or at least a sympathetic soul who was willing to allow a good southern boy to hide in their barn until the danger had passed
in the dark game, how does the author develop the central idea that elizabeth van lew was a spymaster during the civil war?
by including details about the work that van lew did
by recounting an anecdote that van lew tells in her own words
by illustrating the technology that van lew had available to her
by citing an example of van lews coded messages

Explanation:

To develop the central idea that Elizabeth Van Lew was a spymaster, the author would use details about her work. Recounting an anecdote she tells in her own words might not be as comprehensive as detailing her actual spy - related work. Illustrating the technology available to her is more about the tools rather than her role as a spymaster. Citing a single example of coded messages is too narrow. Including details about her work (such as organizing a spy network, gathering intelligence, etc.) would effectively show her as a spymaster.

Answer:

by including details about the work that Van Lew did
