Twо grоups оf students аttempted to re-creаte the primitive аtmospheric conditions of early Earth using the apparatus represented below. Each group ran the experiment with different gas mixtures in the apparatus. The two apparatuses are the same except for the gases being used. The apparatuses are as follows, from top left clockwise: there is a horizontal pipe with an arrow pointing to the right. The pipe bends down into a round area labeled Gases. There are two wires carrying electric current into the gases, and a label indicating Spark Discharge where the wires enter the round area. From there, a pipe continues down through a condenser, with an arrow pointing straight down next to the pipe. Water Out to the right is indicated at the top of the condenser, and Water In to the left is indicated at the bottom of the condenser. Below the condenser, the pipe continues and there is another arrow pointing straight down. The pipe then curves to the left and bends around a trap, which is labeled Water Containing Organic Compounds. The pipe continues to the left to a round area labeled Boiling Water. The pipe continues up from there, and there is an arrow next to it pointing straight up. There is a branch in the pipe about halfway up the left side of the apparatus, labeled To Vacuum Line, with an arrow pointing to the left. The pipe continues past the branch to where it started. The Gases area in Experiment 1 is labeled: N 2, C H 4, N H 3, H 2 O, and C O 2. The Gases area in Experiment 2 is labeled: S O 2, H 2 S, H 2 O, C H 4, and C O 2. Which of the following statements best justifies the claim that the conditions in at least one of the experiments could generate the molecular building blocks essential for life?
