ARGUMENT 1:
Woven baskets characterized by a particular distinctive pattern have previously been found only in the immediate vicinity of the prehistoric village of Palea and therefore were believed to have been made only by the Palean people. Recently, however, archaeologists discovered such a 'Palean' basket in Lithos, an ancient village across the Brim River from Palea. The Brim River is very deep and broad, and so the ancient Paleans could have crossed it only by boat, and no Palean boats have been found. Thus it follows that the so-called Palean baskets were not uniquely Palean.
Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.
主旨句:
Before we get to the conclusion that the so-called Palean baskets were not uniquely Palean, we need to figure out whether the 'Palean' basket found in Lithos were real and the possibility that the ancient Paleans may reach Lithos.
ARGUMENT 2:
"A recent study of eighteen rhesus monkeys provides clues as to the effects of birth order on an individual's levels of stimulation. The study showed that in stimulating situations (such as an encounter with an unfamiliar monkey), firstborn infant monkeys produce up to twice as much of the hormone cortisol, which primes the body for increased activity levels, as do their younger siblings. Firstborn humans also produce relatively high levels of cortisol in stimulating situations (such as the return of a parent after an absence). The study also found that during pregnancy, first-time mother monkeys had higher levels of cortisol than did those who had had several offspring."
Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation(s) can plausibly account for the facts presented in the argument.
主旨句:
To better access the argument, we need to scrutinize whether the samples involved in the study is enough or not, whether monkeys and humans share exactly the similariy that they can be compared in the study, and the association between first-time mother and firstborn infants.
ARGUMENT 8:
The following appeared in a memo from the director of student housing at Buckingham College.
"To serve the housing needs of our students, Buckingham College should build a number of new dormitories. Buckingham's enrollment is growing and, based on current trends, will double over the next 50 years, thus making existing dormitory space inadequate. Moreover, the average rent for an apartment in our town has risen in recent years. Consequently, students will find it increasingly difficult to afford off-campus housing. Finally, attractive new dormitories would make prospective students more likely to enroll at Buckingham."
Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.
主旨句:
In order to appraise the proposal mentioned above, we still need to examine the matriculation trends in Buckingham, the price of the average rent in town and whether promising students will be more likely to be appealed with the new dorms.
