how does the information in the professor's lecture add to the information in the reading passage about Issac Asimov?

The dead sea
the middle eastern body of water called Bahr Lut in Arabic is known as the Dead sea in english. this body of water is said to be "dead" not because it is the dried-out remnant of a formerly living sea but instead because its high salinity makes it difficult for life-forms to survive in it. the dead sea is a landlocked body of water with the jordan river as its source and no outlet. its high salt content, which results from the rapid evaporation due to the area's extremely high temperature, makes it the saltiest of water on earth.
