In addition to finding an increase of suitable browse, like huckleberry and vine maple, Arthur Einarsen, longtime game biologist in the Pacific Northwest, found quality of browse in the open areas to be substantially more nutritive.

A. Arthur Einarsen’s longtime family with the Pacific Northwest helped him discover areas where deer had an increase in suitable browse.

B. Arthur Einarsen found that deforested feeding grounds provided deer with more and better food.

C. Biologist like Einarsen believe it is important to find additional open areas with suitable browse for deer to inhabit.

D. According to Einarsen, huckleberry and vine maple are examples of vegetation that may someday improve the nutrition of deer in the open areas of the Pacific Northwest.

Paragraph 1: ... By isolating organisms completely from external periodic cues, biologists learned that organisms have internal clocks. For instance, apparently normal daily periods of biological activity were maintained for about a week by the fungus Neurospora when it was intentionally isolated from all geophysical timing cues while orbiting in a space shuttle. The continuation of biological rhythms in an organism without external cues attests to its having an internal clock.

In paragraph 1, the experiment on the fungus Neurospora is mentioned to illustrate: (2)

A. the existence of weekly periods of activity as well as daily ones

B. the finding of evidence that organisms have internal clocks

C. the effect of space on the internal clocks of organisms

D. the isolation of one part of an organism's cycle for study

In fact, damage to the environment by humans is often much more severe than damage by natural events and processes.

Paragraph 6: Ecologists are especially interested to know what factors contribute to the resilience of communities because climax communities all over the world are being severely damaged or destroyed by human activities. The destruction caused by the volcanic explosion of Mount St. Helens, in the northwestern United States, for example, pales in comparison to the destruction caused by humans. We need to know what aspects of a community are most important to the community’s resistance to destruction, as well as its recovery.
