An average sneeze travels at about 100 miles per hour. Rebecca designs an experiment to increase the speed of sneezes. She exposes four participants to different stimulants: pepper, bright light, pollen, and fizzy soda. As each participant sneezes, Rebecca measures the speed of air passing through the nasal passage. What is the control in Rebecca's experiment? A) The four participants B) The different stimulants C) The speed of a typical sneeze D) The speed of the induced sneezes

In Rebecca's experiment, the control group or control condition is the baseline against which the effects of the experimental manipulations are compared. It serves as a standard of comparison to assess any changes observed in the experimental groups.
In this scenario, the control in Rebecca's experiment is: C) The speed of a typical sneeze
The speed of a typical sneeze, which is approximately 100 miles per hour, serves as the control or baseline measurement. It represents the standard sneeze speed against which the speeds of sneezes induced by different stimulants (pepper, bright light, pollen, and fizzy soda) in the participants are compared to assess any variations or changes caused by these stimuli.
