Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. People are often surprised to learn just how long some varieties of trees can live. If asked to estimate the age of the oldest living trees on Earth, they often come up with guesses in the neighborhood of two or perhaps three hundred years. The real answer is considerably larger than that, more than five thousand years. The tree that wins the prize for its considerable maturity is the bristlecone pine of California. This venerable pine predates wonders of the ancient world such as the pyramids of Egypt, the Hanging Gardens of Babylon, and the Colossus of Rhodes. It is not nearly as tall as the giant redwood that is also found in California, and in fact it is actually not very tall compared with many other trees, often little more than five meters in height. This relatively short height may be one of the factors that aid the bristlecone pine living to a ripe old age-high winds and inclement weather cannot easily reach the shorter trees and cause damage. An additional factor that contributes to the long life of the bristlecone pine is that this type of tree has a high percentage of resin, which prevents rot from developing in the tree trunk and branches.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. Coincident with concerns about the accelerating loss of species and habitats has been growing appreciation of the importance of biological diversity, the number of species in a particular ecosystem, to the health of the Earth and human well-being. Much has been written about the diversity of terrestrial organisms, particularly the exceptionally rich life associated with tropical rain-forest habitats. Relatively little has been said, however, about diversity of life in the sea even though coral reef systems are comparable to rain forests in terms of richness of life. An alien exploring Earth would probably give priority to the planet’s dominants, most-distinctive feature - the ocean. Humans have a bias toward land that sometimes gets in the way of truly examining global issues. Seen from far away, it is easy to realize that landmasses occupy only one-third of the Earth’s surface. Given that two thirds of the Earth’s surface is water and that marine life lives at all levels of the ocean, the total three-dimensional living space of the ocean is perhaps 100 times greater than that of land and contains more than 90 percent of all life on Earth even though the ocean has fewer distinct species. The fact that half of the known species are thought to inhabit the world’s rain forests does not seem surprising, considering the huge number of insects that comprise the bulk of the species. One scientist found many different species of ants in just one tree from a rain forest. While every species is different from every other species, their genetic makeup constrains them to be insects and to share similar characteristics with 750,000 species of insects. If basic, broad categories such as phyla and classes are given more emphasis than differentiating between species, then the greatest diversity of life is unquestionably the sea. Nearly every major type of plant and animal has some representation there.To appreciate fully the diversity and abundance of life in the sea, it helps to think small. Every spoonful of ocean water contains life, on the order of 100 to 100,000 bacterial cells plus assorted microscopic plants and animals, including larvae of organisms ranging from sponges and corals to starfish and clams and much more.
