Miller and Urey's 1954 Hot Chemistry Experiment Was Based on the Assumption

Multiple Choice

Miller and Urey's 1954 hot chemistry experiment was based on the assumption that Earth's early atmosphere contained water (H₂O) vapor, methane, hydrogen, and ammonia.Subsequent research showed that volcanoes released carbon dioxide (CO₂) , hydrogen sulfide (H₂S) , and sulfur dioxide (SO₂) around 4 billion years ago.In response to this evidence, scientists concluded that

A) no synthesis of prebiotic molecules was possible on early Earth.
B) the experiment needed to be repeated with the inclusion of CO₂, SO₂, and H₂O.
C) the experiment needed to be repeated with the inclusion of CO₂, SO₂, and H₂S.
D) the experiment needed to be repeated with the inclusion of CO₂, SO₂, and H₂S, and the exclusion of the original gases.
E) the experiment needed to be repeated in the vicinity of an active volcano and with the inclusion of CO₂, SO₂, and H₂S.
