conclusion:
So only if the temperature in the Brazilian ash’s environment never exceeds 95 degrees Fahrenheit will its rings be a reliable measure of the tree’s age.
laymans term - if temp does not exceed 95 F then you can count rings.
negation test: E. The number of rings that will be lost when the temperature exceeds 95 degrees Fahrenheit is not predictable.
The number of rings that will be lost when the temperature exceeds 95 degrees Fahrenheit is predictable. (remove not)
