GRE作文改革后对argument写作所造成的变化

　　Finally, granted that the deer populations do decline due to increased local temperatures associated with the global warming, concrete evidence still remains desirable to evaluate the authors assertion that it is via disturbing the deers migration patterns that the warmer climate reduces the populations. As mentioned above, the survival of deer relies on numerous factors, many of which are likely to be affected by temperature, and hence evidence from investigation into all these temperature dependent factors has to be obtained. Provided that such evidence reveals, for instance, that the higher temperatures endanger plants the deer mainly feed on and that the population drop is a result of food shortage caused by increased temperatures but not inability to migrate, the conclusion of the argument will prove untenable. Conversely, evidence undoubtedly exhibiting that the warmer climate melts the sea ice and leads to the deers failure to follow the old-aged migration pattern and ultimately their massive death will be in strong support of the proposed reason for the drop of deer populations in the argument.

　　To sum up, evidence beyond what has been brought forward by the author is required for a legitimate evaluation of the reasoning and conclusion of the argument. Specifically, detailed and reliable evidence concerning the deer populations, the climate change in the arctic regions, as well as all the factors that are capable of affecting the deer populations, whether temperature dependent or not, will be helpful with evaluating the credibility of the argument.
