Ukusetshenziswa kwengilazi yephrofayela ye-U emhubheni phakathi kwamayunithi amabili esakhiweni kuyisengezo esihle esithuthukisa ubumfihlo bamakhasimende esitezi sokuqala kuyilapho kukhulisa inani lokukhanya kwemvelo okuza esikhaleni. Lesi sixazululo sokuklama sibonisa ukuthi abaklami bezakhiwo nabaklami bahlale befuna izindlela ezintsha zokuthuthukisa ulwazi lwamakhasimende.
