Refer to the following passage for questions 1 through 4. When using a metal file, always remember to bear down on the forward stroke only. On the return stroke, lift the file clear of the surface to avoid dulling the instrument’s teeth. Only when working on very soft metals is it advisable to drag the file’s teeth slightly on the return stroke. This helps clear out metal pieces from between the teeth. It is best to bear down just hard enough to keep the file cutting at all times. Too little pressure uses only the tips of the teeth, while too much pressure can chip the teeth. Move the file in straight lines across the surface. Use a vise to grip the work so that your hands are free to hold the file. Protect your hands by equipping the file with a handle. Buy a wooden handle and install it by inserting the pointed end of the file into the handle hole.

PARK WILDLIFE Sequoia and Kings Canyon National Parks support a wide diversity of animal species, reflecting the range in elevation, climate, and habitat variety there. Over 260 native vertebrate species are in the parks; numerous additional species may be present but have not been confirmed. Of the native vertebrates, five species are extirpated (or extinct), and over 150 are rare or uncommon. There have been some studies of invertebrates in the area, but there is not enough information to know how many species occur specifically in the parks. Many of the parks’ caves contain invertebrates, some of which exist only in one cave and are known nowhere else in the world. In the foothills, where summers are hot and dry and winters are mild, plant life is largely chaparral on the lower slopes, with blue oak and California buckeye in the valleys and on higher slopes. A number of animals live in this area year-round; some breed here, while others winter here. Local species include the gray fox, bobcat, striped and spotted skunks, black bear, wood rat, pocket gopher, white-footed mouse, California quail, scrub jay, lesser goldfinch, wrentit, acorn woodpecker, gopher snake, California king snake, striped racer, western whiptail lizard, and the California newt.
