The popular notion that a tree's age can be determined by counting number of internal rings in its trunk is generally true. Howeevr, to help regulate the internal temperature of the tree, the outermost layers of wood of the Brazilian ash often →peel away when the temperature exceeds 95 degrees Fahrenheit, leaving the tree with fewer rings than it would otherwise have. So only if the temperature in the Brazilian ash's environment never exceeds 95 degrees Fahrenheit →elav eing the tree with fewer rings than it would otherwise have. So only if the reliable measure of the tree's age. Which of the following is an assumption on whish the argument above depends?
A The growth of new rings in a trees is not a function of levels of precipitation.
B Only the Brazilaian ash loses rings because of excessive heat.
C One day of temperatures above 95 degrees Fahrenheit will cause the Brazilian ash to lose one ring.
D The internal rings of all tress are of uniform thickness
