Francisco Reddi performed a famous experiment in the 1600s to disprove the Theory of Spontaneous Generation. He took two pieces of identical meat, put them in two jars in the same location. The first jar he left open at the top; the second he covered the top so flies could not get in. After five days there were maggots all over the jar that had been left uncovered; none on the second jar. This proves that maggots come from flies; life comes from life. Pick the control group below for this experiment:

• The second covered jars

• The flies

• The meat, location, time (five days)

• The first uncovered jar
