as a result of the cut cables, germany lost its most secure
long-distance communications system. the germans now
had to rely on radio transmissions from their powerful
wireless station at nauen, a few miles from berlin. which
was exactly what the british military knew they would have
to do. and once the germans began sending wireless
messages, mi8, the british code breakers, began plucking
them from the air. of course, all german correspondence
was sent in a complicated cipher system, so that was when
the hard work began for the code breakers of mi8.

What type of writing is demonstrated in this excerpt by general philip henry sheridan? at once i set about preparing for the examination which precedes admission to the military academy, studying zealously under the direction of mr. william clark; my old teachers, mcnanly and thorn, having disappeared from somerset and sought new fields of usefulness. the intervening months passed rapidly away, and i fear that i did not make much progress, yet i thought i should be able to pass the preliminary examination. that which was to follow worried me more and gave me many sleepless nights; but these would have been less in number, i fully believe, had it not been for one specification of my, outfit which the circular that accompanied my appointment demanded. this requirement was a pair of "monroe shoes." now, out in ohio, what "monroe shoes" were was a mystery—not a shoemaker in my section having so much as an inkling of the construction of the perplexing things, until finally my eldest brother brought an idea of them from baltimore, when it was found that they were a familiar pattern under another name. a. research essay b. persuasive essay c. biography d. memoir
