Redi placed pieces of meat in several jars. He divided the jars into two groups. He covered the first group of jars with fine cloth. He left the second group of jars uncovered. Redi observed the jars for several days. He saw files on the cloth of the covered jars, and he saw files laying eggs on the meat in the uncovered jars. Maggots appeared only on the meat in the group of jars left uncovered. What do you think Redi's conclusion was?
a. Living things come from other living things
b. Living things are created through spontaneous generation.
c. He did not have enough data to arrive at a conclusion.
