Question ID:PT58 S2 Q1 Passage:Traditional sources of evidence about ancient history are archaeological remains and surviving texts. Those investigating the crafts practiced by women in ancient times, however, often derive little information from these sources, and the archaeological record is particularly unavailing for the study of ancient textile production, as researchers are thwarted by the perishable nature of cloth. What shreds persisted through millennia were, until recently, often discarded by excavators as useless, as were loom weights, which appeared to be nothing more than blobs of clay. Ancient texts, meanwhile, rarely mention the creation of textiles; moreover, those references that do exist use archaic, unrevealing terminology. Yet despite these obstacles, researchers have learned a great deal about ancient textiles and those who made them, and also about how to piece together a whole picture from many disparate sources of evidence.Technological advances in the analysis of archaeological remains provide much more information than was previously available, especially about minute remains. Successful modern methods include radiocarbon dating, infrared photography for seeing through dirt without removing it, isotope "fingerprinting" for tracing sources of raw materials, and thin-layer chromatography for analyzing dyes. As if in preparation for such advances, the field of archaeology has also undergone an important philosophical revolution in the past century. Once little more than a self-serving quest for artifacts to stock museums and private collections, the field has transformed itself into a scientific pursuit of knowledge about past cultures. As part of this process, archaeologists adopted the fundamental precept of preserving all objects, even those that have no immediately discernible value. Thus in the 1970s two researchers found the oldest known complete garment, a 5,000-year-old linen shirt, among a tumbled heap of dirty linens that had been preserved as part of the well-known Petrie collection decades before anyone began to study the history of textiles.The history of textiles and of the craftswomen who produced them has also advanced on a different front: recreating the actual production of cloth. Reconstructing and implementing ancient production methods provides a valuable way of generating and checking hypotheses. For example, these techniques made it possible to confirm that the excavated pieces of clay once considered useless in fact functioned as loom weights. Similarly, scholars have until recently been obliged to speculate as to which one of two statues of Athena, one large and one small, was adorned with a dress created by a group of Athenian women for a festival, as described in surviving texts. Because records show that it took nine months to produce the dress, scholars assumed it must have adorned the large statue. But by investigating the methods of production and the size of the looms used, researchers have ascertained that in fact a dress for the small statue would have taken nine months to produce. Stem:Which one of the following most accurately expresses the main point of the passage? Correct Answer Choice:BChoice A:Archaeology is an expanding discipline that has transformed itself in response both to scientific advances and to changing cultural demands such as a recently increasing interest in women's history. Choice B:A diversity of new approaches to the study of ancient textiles has enabled researchers to infer much about the history of textiles and their creators in the ancient world from the scant evidence that remains. Choice C:Despite many obstacles, research into the textile production methods used by women in the ancient world has advanced over the past century to the point that archaeologists can now replicate ancient equipment and production techniques. Choice D:Research into the history of textiles has spurred sweeping changes in the field of archaeology, from the application of advanced technology to the revaluation of ancient artifacts that were once deemed useless. Choice E:Though researchers have verified certain theories about the history of textiles by using technological developments such as radiocarbon dating, most significant findings in this field have grown out of the reconstruction of ancient production techniques.
