Professor Tompkins notices that rats run quickly through a maze when exposed to loud noise. Identify which of the following is necessary to transform this observation into a two-group experimental design?
A) multiple comparison conditions where rats run through mazes while exposed to several different volumes of noise
B) multiple rats to observe running through the maze with loud noise
C) a control condition where rats run through a maze without exposure to loud noise
D) a subjective way to measure how fast a rat runs

To transform this observation into a two-group experimental design, a control condition is necessary where rats run through a maze without exposure to loud noise. This will allow for a comparison between the group of rats exposed to loud noise and the control group, which would help identify if the loud noise is indeed causing the rats to run quickly through the maze. The other options do not necessarily involve a two-group experimental design.
