Ubani ngempela owasungula ucingo?
Context:Ukuhlonishwa kokusungulwa kocingo lukagesi kuvame ukuphikiswa, futhi kuphakama izingxabano ezintsha ngale ndaba ngezikhathi ezithile. U - Antonio Meucci, u - Alexander Graham Bell, no - Elisha Gray phakathi kwabanye, bonke baye babongwa ngokuqamba ucingo. Umlando wokuqala wocingo waba futhi usalokhu uyisikhukhula esiyindida sezimangalo neziphikiso, ezazingacaciswanga ngenani elikhulu lamacala afakwe ukuze kuxazululwe izimangalo zamalungelo obunikazi zabantu abaningi kanye nabancintisana nabo kwezentengiselwano. Nokho, amalungelo obunikazi kaBell no-Edison ayebaluleke kakhulu kwezentengiselwano, ngoba ayebusa ubuchwepheshe bezingcingo futhi asekelwa izinqumo zenkantolo e-United States.  Ucingo lwanamuhla luwumphumela womsebenzi wabantu abaningi. Nokho, uAlexander Graham Bell waba ngowokuqala ukuthola ilungelo lobunikazi ngocingo, "njengomshini wokudlulisela imisindo yezwi noma eminye nge-telegraph". Ngokuvamile uBell uye wabhekwa njengomsunguli wocingo lokuqala olusebenzayo. UJohann Philipp Reis wasungula igama elithi "ucingo". Amamodeli alo athunyelwa phesheya, eLondon, eDublin, eTiflis, nakwezinye izindawo. Yaba isihloko sezinkulumo ezithandwayo, nesihloko sezinkulumo zesayensi. U-Edison wathi "wayengumsunguli wokuqala wocingo". Umsunguli wase-Italy-American nosomabhizinisi u-Antonio Meucci uye wahlonishwa yiNdlu Yabamele Yase-U.S. ngomsebenzi wakhe wokufaka isandla ocingweni. Ezinye izingxabano eziningi nazo ziphathelene nombuzo wobukhulu bokusungulwa kocingo. Impikiswano ngocingo ka-Elisha Gray no-Alexander Bell ibheka umbuzo wokuthi ngabe uBell noGray basungula ucingo ngokuzimela yini, futhi uma kungenjalo, ngabe uBell weba ukusungulwa kukaGray. Le mpikiswano incane kunempikiswano ebanzi yokuthi ubani ofanelwe udumo ngokuqamba ucingo, lapho kunabamangali abaningana.
Ukusungulwa kocingo kuwumphumela weminikelo eminingi phakathi neminyaka. Owaziwa kakhulu, u-Antonio Meucci, u-Alexander Graham Bell, no-Elisha Gray basiza ekwakheni ucingo njengoba silwazi namuhla. Abantu abaningana babethi yibo abakhiqize lokhu kodwa singasho kalula ukuthi lokhu kusungula kuwumphumela wokubambisana kwesintu ukwenza lula ukuxhumana nokusondeza abantu emhlabeni wonke.
