1. As evidence that postperovskite is present in Earth’s mantle, the passage mentionsthe
A. timing of developments in the evolution of life on Earth - this is presented as a consequence not an evidience
B. different minerals predominating at different depths in the core - Not used in support of alternatehypothesis
C. results of exposing magnesium silicate to high pressures and temperatures - Experiment proved that, and that evidience was used to suppot this alternatehypothesis
D. indirectly measured temperature of Earth’s inner core - No such expt. conducted
E. dangers that genetic mutations pose for life on Earth - No it was a conclusion notevidience
2. According to the passage, the scientists’ hypothesis that the early Earth’s core must have been hotter than previously thought is basedon
Passage says: Because postperovskite would conduct heat away from Earth’s core more rapidly than perovskitewould , scientists hypothesize that the early Earth’s
