1. Greenwood is a growing neighborhood in Mintonport. Since Greenwood's population is now slightly larger than that of some neighborhoods that have their own branch libraries in Mintonport's public library system, Greenwood residents contend that the city ought to build a branch library there. Opponents argue that such a branch library would be underutilized, because Greenwood residents visit public libraries only half as often as do other city residents living in neighborhoods without branch libraries.   
Which of the following, if true, provides the strongest rebuttal to the opponents' argument?
A. Mintonport has never closed any branch library because it was underutilized.
B. In comparison with other neighborhoods, Greenwood has greater access to many city services.
C. The libraries of public libraries are not as convenient for Greenwood residents as they are for residents of other neighborhoods that lack branch libraries.
D. Most residents of Greenwood have moved there within the last five years.
E. It costs the city more to operate a branch library today than it did 10 to 20 years ago, when most of the current branch libraries were built.



2.Journalist: For a long time there was widespread agreement among scholars that chickens were not in the Americas until the Spaniards arrived there in the sixteenth century. Recently, however, scientists analyzed the DNA of a chicken bone recovered from an archaeological site in South America. They found that its DNA sequence was identical to chicken remains recovered from archaeological sites on the Polynesian islands of Tong and American Samoa. The South American chicken bone was dated to a period between AD 1321 and 1407, a period during which the easternmost islands of Polynesia were being colonized before Europeans arrived.
Which of the following is most strongly supported by the information provided by the journalist?
A. Chickens were first domesticated somewhere in the region of Polynesia.
B. People may have traveled between the Polynesian islands and South America before Spaniards came to South America.
C. Chickens spread from the Americas to Europe, rather than the reverse.
D. The original colonizers of Polynesia may have originated in South America.
E. Chickens may have been first brought to Polynesia and to the Americas by Europeans.

2. 看成了加强题， 其实是归纳- conclusion。
根据文章可以推断， 早在欧洲人来之前， P上的人就已经和南美的人有来往， 才有了鸡的基因类似的结果。

P1 city ought to build a branch library
P2 visit public libraries only half as often as do other city residents living in neighborhoods without branch libraries
C  such a branch library would be underutilized
2. [Conclusion] A ❌ B
学者长期认为，16世纪西班牙人到达美洲之后，美洲才有鸡。
南美一处遗址中鸡骨的DNA序列=P of T 和美属S遗址中鸡肉残骸。 南美鸡骨在公元1321-1407年，早于欧洲人的殖民期。
有点迷惑A问题应该出在domestic上，B我不懂哪里体现travel了，可能人到那里去就指travel，还是对原文判断不准确；搬运解析
正确答案B: 在西班牙人来到南美洲之前，人们可能已经在波利尼西亚群岛和南 美洲之间旅行。
根据鸡骨DNA比较，鸡是人带去的，正确
选项A: 解释不了异地DNA相同，非正确选项
选项C: 没有证据，非正确选项
选项D: 题干未涉及，非正确选项
选项E: 与题干给的新发现相悖，非正确选项

2.原来人们以为鸡是西班牙人带到美洲的 但考古发现南美洲的鸡和P岛上的鸡基因序列相同 然后南美洲的鸡存在于1321这个时间段 此时P岛上还没有欧洲人

捋一下逻辑：首先?肯定是被谁带到美洲去的 那题目给了一个P岛 那说明?是从P岛带到美洲的 那这个时候还没有欧洲人什么事儿 肯定是被别人从P岛带到美洲去的
A.在哪里驯化的和本题无关
B.对 就是因为人们之前就在两地往返 所以才在欧洲人involve之前 就把鸡从P岛弄到美洲
C.欧洲的鸡可能是从P岛引入的 也可能是从美国引入的 都有可能 不能说就是从美洲到欧洲的
D.在说鸡的事 和殖民者无关
E.不是的assume p岛 美洲 欧洲 这三个地方最早拥有鸡的是P岛
