After reading the paragraph below, answer the questions that follow The redwood groves in Northern California are one of America's greatest natural resources. Redwoods can live more than 2,000 years and grow taller than 350 feet. When tourism became popular in the late 1800s, large tunnels were cut through the center of several of these giant trees to allow wagons to pass through (and to attract tourists to the location). Even today, visitors wait in line to be photographed driving their cars through a tunnel. When the groves were converted into national parks, the tunneling was discontinued, but several tunneled trees are still alive. -When the redwood tunnels were first constructed, not much consideration was given to the long-term effects of a tunnel on a tree's health. Nevertheless, many trees have survived more than 100 years after a tunnel was cut through their trunks. This is possible because

In Utah there is a clone of aspen trees that covers over 100 acres. Such clones can be considered to be a single plant with many stems. It appears that the first stem of this clone originated over 80,000 years ago, even before there were humans in North America. Which of the following likely contributes most to the long-term survival (long life span)of aspens?
