Wow! Looks like a full day went by, and then some. Wearin' o'the green, and all that?
Here's a question that has nothing to do with statistics or trial-and-error; IOW a change for me.
Briefly, in your own words, sketch how the westbound Taggart Comet stalled out inside the Taggart Tunnel, and the catastrope that took place when an off-schedule Army freight train plowed into it.
You could discuss the "why" of this from the viewpoint of politics (socialism) or the "how" of it from the viewpoint of operations (railroading). Or both, for extra credit.
Try to do two, maybe three short paragraphs max, maybe 100 - 150 words. Less than a full page in business-letter format.
Hint no. 1: This is from fiction, a novel that was first published in 1957.
Hint no. 2: This is the longest novel the author ever wrote in terms of pages; but the novel that has sold the most continues to be the one she wrote and had published in 1943, about a very gifted and idealistic architect.
Should be a piece o' green coconut cake!
