Juanita Recently Told Me That 98% of Businesses Emit Toxins

Multiple Choice

Juanita recently told me that 98% of businesses emit toxins into the environment. I informed her that I thought that number had to be incorrect because not 98% of businesses are manufacturers. She said, hastily, "well that is the figure the EPA is using". Which method of knowing is Juanita relying upon?

A) Tradition
B) Expert authority
C) Intuition and personal experiences
D) Scientific method
