Question

on a cold winter’s day in 1980, a group of recreational cavers entered a narrow, wet stream passage south of knoxville, tennessee. they navigated a slippery mud slope and a tight keyhole through the cave wall, trudged through the stream itself, ducked through another keyhole, and climbed more mud. eventually, they entered a high and relatively dry passage deep in the cave’s “dark zone” – beyond the reach of external light. on the walls around them, they began to see lines and figures traced into remnant mud banks laid down long ago when the stream flowed at this higher level. no modern or historic graffiti marred the surfaces. they saw images of animals, people, and transformational characters blending human characteristics with those of birds, and those of snakes with mammals. ancient cave art has long been one of the most compelling of all artifacts from the human past, fascinating both to scientists and to the public at large. its visual expressions resonate across the ages, as if the ancients speak to us from deep in time. remarkably, this group of cavers in 1980 had happened upon the first ancient cave art site in north america. since then, archaeologists like me have discovered dozens more of these cave art sites in the southeast. we’ve been able to learn details about when cave art first appeared in the region, when it was most frequently produced, and what it might have been used for. we have also learned a great deal by working with the living descendants of the cave art makers, the present-day native american peoples of the southeast, about what the cave art means and how important it was and is to indigenous communities. cave art in america? assessment questions question 24 how does the overall structure of the article contribute to its effectiveness? a. the description of how long it took archeologists to find cave art highlights how rare it is in the southeast. b. the description of the different types of caves that art has been found in emphasizes how varied cave art can be. c. the description of how long it takes to authenticate cave art suggests that scientists are uninterested in cave art d. the description of the different places and time periods from which cave art was found indicates how prevalent it is

Explanation:

To solve this, we analyze each option:

• Option A: The article doesn't focus on how long archaeologists took to find cave art or its rarity in the Southeast. Eliminate A.
• Option B: The article isn't about different types of caves cave art is found in. Eliminate B.
• Option C: There's no mention of authentication time or scientists being uninterested. Eliminate C.
• Option D: The text says archaeologists discovered dozens more sites, learned about when it appeared, etc. Describing different places (dozens of sites in the Southeast) and time periods (when it first appeared, most frequent production) shows its prevalence. This matches.

Answer:

D. The description of the different places and time periods from which cave art was found indicates how prevalent it is.
