【正文】 l painting, the woman wears a light cloth that illuminated her face. Thus the presentation of light and shadow was indeed very realistic and accurate, as it is characteristic of Rembrandt’s paintings. Finally, the mystery of the panel consisting of patches glued together is also solved in the lecture. Actually, the wood panel was later enlarged to make it more grand and valuable, but the original painting was painted on a single panel, as Rembrandt would have done it. Furthermore, the wood is of the same tree used in other Rembrandt paintings, like the SelfPortrait with a Hat”. All this information points to Rembrandt as the painter of the controversial painting. TPO4（滿分版） The professor actually contradicts the statements made in the passage. She is of the view that dinosaurs are not endotherms . they were not able to keep their body temperature at a constant rate. The professor contradicts the issue of dinosaurs being endotherms based on the availability of fossils being available in the polar regions, she say that the polar regions in those days were not as cold as they are today at least warm enough for dinosaurs to live. During harsh winters she says that there is a possibility of the dinosaurs actually migrating to warmer regions. The issue of leg position and movement being used as a reason to classify the dinosaurs as endotherms does not please the professor either. She says that dinosaurs had legs under their bodies to support their huge bodies the legs under the body of the dinosaur were actually to support the huge weight of the dinosaur and not to provide it with a body structure like endotherms(which is actually suited for running). The professor acknowledges the presence of haversian canals but also points out that that the fossils show the presence of growth rings. These rings occur due to the thickening of the bone. The thickening indicates that the dinosaurs weren’t actually growing continuously but were experiencing periods of rapid growth and periods of no growth in succession. This pattern. She says is characteristic of non endothermic animals. Thus it can be inferred that the professor challenges the passage by giving reasons as to why she thinks that the dinosaur is not an endotherm. TPO 5 The author of the reading passage proposes three theories as likely explanations of the primary function of Chaco Canyon houses, grant structures built in the I2th century. The lecturer, however, points to the inaccuracies in each of these theories. The lecturer argues that the modest number of fireplaces in these structures is in contradiction with the huge size of these houses, indicating that these structures could not have been used for Residential purposes. The Reading, however, draws parisons between the Chaco houses and other similar large Residential structures in support of the Residential theory. The second theory, that the houses were used for food storage, is also rejected by the lecturer. He explains that a place that had been used for storing maize would have many traces of scattered Maize, which is not the case in the area of the Chaco Canyon houses. This proves that the food storage theory is unlikely. Finally, regarding the third theory, the ceremony theory39。39。s ecofriendly practices. The passage explains that it is not necessary for American wood panies to pursue ecocertification while the lecture provides several counterarguments to this view. First, the lecturer argues that the reading passage is too general in its statement that American consumers reject advertising pletely. He asserts that Americans do not trust advertising claims for a product only when these claims are made by the pany that sells the product. When a claim is made by an independent third party such as a wood certification pany, he posits, consumers respond very positively with strong acceptance of the certified product. The lecturer also refutes the second point in the reading that pricesensitive American consumers are likely to choose cheap wood products without certification. The professor contends that certified wood is only slightly (less than 5%) more expensive than uncertified wood, and therefore, he argues, consumers will tend to ignore the price difference and choose the ecofriendly product. Finally, receiving ecocertification is, according to the professor, an important strategy used by American wood panies to ensure that their products can pete against ecocertified wood products imported into the domestic market from foreign countries.
