In Southwest France in the 1940’s； playing children discovered Lascaux Grotto； a series of narrow cave chambers that contain huge prehistoric paintings of animals。 Many of these beasts are as large as 16 feet （almost 5 meters）。 Some follow each other in solemn parades； but others swirl about； sideways and upside down。 The animals are bulls； wild horses； reindeer； bison； and mammoths outlined with charcoal and painted mostly in reds； yellow； and browns。 Scientific analysis reveals that the colors were derived from ocher and other iron oxides ground into a fine powder。 Methods of applying color varied： some colors were brushed or smeared on rock surfaces and others were blown or sprayed。 It is possible that tubes made from animal bones were used for spraying because hollow bones； some stained with pigment； have been found nearby。
這道題詢問從洞穴中發現的骨頭可以得到什麼結論。根據關鍵詞bones，可以定位到該段的末尾句。
根據tubes made from animal bones were used for spraying以及some stained with pigment，可以知道將空心的骨頭當做繪畫工具的方法。故選第4項。
