TPO9

The lecturer points out several problems with the use of hydrogen-based fuel-cell engines in support of her claim that substituting them for internal-combustion engines is technologically unfeasible, environmentally unfriendly, and economically unviable.

First, the lecturer states that it is impractical to replace internal-

combustion engines with fuel-cell engines because using the latter requires hydrogen in a pure liquid form, which is technologically challenging to both obtain and store. However, the reading argues that because hydrogen can be extracted from many resources including water, fuel cell engines powered by this infinite source of energy are an extremely attractive alternative.

Second, the lecturer refutes the claim in the reading that hydrogen cells are environmentally friendly. She argues that although engines that use hydrogen cells produce less pollution, the manufacturing of hydrogen cells generates large amounts of harmful by-products due to the burning of fossil fuels in the purification process.

Third, although the reading suggests that hydrogen-based engines are more fuel-efficient and thus economically competitive than internal-

combustion engines, the professor argues that such an advantage is

undermined by the fact that fuel-cell engines are extremely expensive to manufacture because they require the addition of platinum, a very rare and expensive material.

TPO10

The lecturer and the reading passage suggest two competing theories, the predation theory vs. the pollution theory, to explain why the sea otter population is in rapid decline.

The professor reasons that the absence of dead sea otters washed up the coast suggests that their decline is not caused by sea pollution but rather by sea predators who consume their bodies after Killing them. In contrast, the reading passage attributes the death of sea otters to pollution, citing evidence of

increased sources of ocean contaminants which lead to greater vulnerability to infections.

Furthermore, the lecturer argues that orcas are likely factors in the

disappearance of sea otters, because the scarcity of whales, their usual prey, has left them with no other choice but to start hunting smaller mammals like the otters for food. The reading passage, on the other hand, Rules out this theory based on the orca’s preying habit, and instead approves of the pollution theory as the only explanation for the decline op both large and small sea mammals across the entire ecosystem.

Finally, according to the lecturer, the uneven pattern of sea otter decline corresponds to the distribution of the orcas. She argues that the pact that their population has declined most rapidly where orcas are most prevalent further validates the predation theory. However, the reading passage argues that changeable environmental factors, which lead to different concentrations of pollutants, better explains the varying pattern of sea otter decline.

TPO3

The lecture revises the idea presented in the text, that Rembrandt was not the artist who painted the famous painting “Portrait of an Elderly Woman in a White Bonnet”.

The inconsistency between the white cap, which identifies the woman as a servant, and the expensive fur collar she wears dissolves as the Professor

explains that the fur collar was apparently painted over the original painting to increase its worth by displaying an aristocratic woman.

In addition, the assumption that light and shadow in the painting do not fit together is refuted by the fact that in the original 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 “Self-Portrait with a Hat”.

All this information points to Rembrandt as the painter of the controversial painting.

TPO4

The professor actually contradicts the statements made in the passage. She is of the view that dinosaurs are not endotherms i.e. 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 i.e 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 i.e 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 suit(转 载 于:wWW.zw2.Cn 爱作文网)ed 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.
