Robert E. Peary was a well-known adventurer and arctic explorer who in 1909 set out to reach the North Pole. When he returned from the expedition, he claimed to have reached the pole on April 7, 1909. This report made him into an international celebrity. Though some historians have expressed doubts that Peary did in fact reach the North Pole, three arguments provide strong support for the truth of Peary's claim. First, the National Geographic Society put together a committee that was instructed to conduct a thorough investigation of Peary's records and equipment. At the end of the investigation, the committee concluded that Peary's accounts were consistent and persuasive and declared that he had indeed reached the North Pole. Second, a recent expedition provides support for Peary's claim that he reached the North Pole in only 37 days after setting out from Ellesmere Island off the coast of Greenland. Skeptics used to argue that Peary could not have traveled that fast, since even modern snowmobiles take longer to cover the same distance. However, a British explorer named Tom Avery recently made the same trek in less than 37 days. In fact, Avery used the same kind of dogsled and the same number and breed of dogs as Peary had. Thus, Peary's claims are not impossible, and he very well might have been telling the truth. Third, there are photographs taken by Peary that support his claim to have reached the North Pole. Measuring the shadows in Peary's photographs makes it possible to calculate the Surf s position in the sun. The Surf s position established from the photographs corresponds exactly to the Surf s position as it should have been at the North Pole on that day. This provides strong evidence that Peary reached the North Pole and took the photographs there.
In the reading passage, the writer contends that Robert E. Peary, a well-known adventurer and arctic explorer, have reached the North Pole according to three evidences. However, the professor in the lecture contradicts this view with three specific points to support her idea.
Firstly, even though the reading passage suggests that the committee instructed to conduct a thorough investigation of Peary's records and equipment concluded that his accounts were consistent and persuasive, the professor refutes it. This is because that this committee is not objective, composed of Peary's best friend, who also funded his adventure to the Pole. Besides, this investigation only took two days, which means it might be careless and unconvincing.
Secondly, in opposition to the statement in the reading passage, the professor insists that a recent expedition made by Tom Avery fails to eliminate the doubt on the travelling speed of Peary,.Then she confirms this with the fact that Avery did not take the food with him on the snowmobiles but use an airplane to throw it to the land instead. However, Peary put his supply on the snowmobiles. In this case, it is impossible for him to achieve this trip in such a short period.
Last but not least, according to the reading passage, the Surf's position can be speculated by the shadows in Peary's photographs. Nevertheless, the professor asserts that as the photos were taken more than 100 years ago, it is not scientific and reliable to calculate the position according to the blur and faded photographs.
In conclusion, the professor clearly pinpoints the weaknesses in the reading passage.
