in the dark game, how does the author develop the central idea that elizabeth van lew was a spymaster during the civil war?\nby including details about the work that van lew did\nby recounting an anecdote that van lew tells in her own words\nby citing an example of van lew’s coded messages\nby illustrating the technology that van lew had available to her
Answer
Brief Explanations:
In a text, details about a person's work - in this case Van Lew's work as a spymaster - help develop the central idea that she held that role. Recounting an anecdote in her own words doesn't directly develop the idea of her being a spymaster as strongly as details of her work. Citing a single coded - message example is too narrow, and illustrating available technology doesn't directly show her role as a spymaster.
Answer:
by including details about the work that Van Lew did
