Describe how the Navajo Code was created. Provide and explain one example of how a phrase was changed and one example of how

an alphabetic sound was changed

The Navajo code was created by Philip Johnston. His father was a missionary, who spent years on a Navajo reservation, allowing Philip to grow up in contact with the language of the Navajo people, which made him learn this language fluently. The Navajo language was very complex, difficult to pronounce and write, which meant that very few people in the world, apart from the Navajos, could understand and learn that language.

Thus, the Navajo language became ideal for messages to be transmitted during the Second World War, without the enemy's army being able to decipher it.

The Navajo code was assembled by a set of Navajo words, where each word symbolized a phrase or other words in the English language.

An example is the word SO-A-LA-IH. In Navajo, this word means "star", but in the Navajo code it symbolized that the message provided was destined for Brigadier General Americano, since his insignia was a star.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
