Answer:  Fessender oscillator

Created by Reginald A. Fessenden, <u>motivated by The Titanic tragedy.</u> It was the first successful acoustical echo ranging system. Given its properties (540‐Hz air‐backed electrodynamically driven clamped‐edge circular plate), morse code could be used to communicate between submarines. During the First World War, the Royal Navy also used it for detecting submarines.

The only disadvantage that this system had, it's that it was reasonably easy to be heard by other ships, even on the surface. On the other hand, it was only useful for detecting big targets, as for little ones, it lacked power

finlep [7]

The main cause is poverty and lack of education. They're very poor, so they can't afford school. If the children do go to school, they drop out very young to work and help earn money for the family. That's not the kind of cycle people can break out of easily. Add to that the civil war from 1960 to 1996 where the military persecuted the native people, killing up to 200,000, and they've had a pretty rough time of it.
