In our lecture about regulation of synthetic chemicals, you learned about a
chemical called Chlorpyrifos, and that there has been some debate within
the United States government (since ~2013) about whether to: (a) ban
this chemical in light of recent evidence of health risks for pregnant
women, as well as birth defects or (b) continue to certify use of this
chemical because of its economic importance for farmers who rely on it.
If we did decide to recall this chemical (Chlorpyrifos), and ban all future
use of it (in light of human health risks), that would be considered part of
our "________________________" philosophical approach to safety/risk
assessment. - answer Innocent Until Proven Guilty
Recall our recent lectures and the Module 12 Reading (IPCC report, Press

Which of the following statements about the IPCC are TRUE? - answer
The IPCC assesses thousands of scientific papers published each year to

Meteorological Organization.

scientists of the IPCC conduct their own research to fill those knowledge
gaps.
