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. -Which of the following correctly lists the sequence of tissues a tunnel would pass through (starting from the outer surface of the tree and passing through the central core)?

A 20-foot-tall tree that seemed to have stopped growing was cut down by the forester who had planted it 43 years earlier, who was concerned that it might be diseased. Measurements over the past 10 years had shown that the tree's height varied only 2 or 3 inches each year, some years with a height increase and some years with a height decrease. Other data indicated that the tree had 41 rings of similar width and had produced similar numbers of nuts every year for the last 30 years. Based on these data, which conclusion was most likely a part of the forester's report on the tree's health?
