The graph above depicts the relative increase in autism in children from 1997 to 2007 living in California. In 2001, the additive thimerosal was removed from most childhood vaccines
Based on the information presented in the graph, what can be concluded about the hypothesis that thimerosal causes autism? A) Thimerosal, at the very least, contributes to the occurrence of autism as evidenced by the almost logarithmic increase in children with autism from 2001 to 2007.
B) Prior to 2001, thimerosal clearly influenced the cases of autism in California.
C) A sharp decrease in the cases of autism would be expected after 2001 if thimerosal was the causative agent of autism.
D) The results of the study are inclusive.
E) Thimerosal requires some other agent to help induce autism.
