这篇文章三道题感觉每一道题是清楚的。好受伤啊，本来阅读就差，打算看看机经也没看懂。。求高手指教！第一题：看了答案之后才觉得C可能是对的，但是自己想就根本确定不了啊。谁能跟我说说这个思路是什么吗？多谢！
第二题：我选的是A，我觉得没有时间上的证据证明那个更早，这应该挺合理的吧。然后看了正确答案是B，也觉得B也有道理
第三题：选D，这个我是看了答案也不知道为什么。
求讲解！任何一个都可以，多谢多谢！
贴文章题目如下：

Since the 1970s, archaeological sites in China's Yangtze River region have yielded
evidence of sophisticated rice-farming societies that predate signs of rice cultivation elsewhere
in East Asia by a thousand years. Before this evidence was discovered, it had generally been
assumed that rice farming began farther to the south. This scenario was based both on the
geographic range of wild or free-living rice, which was not thought to extend as far north as the
Yangtze, and on archaeological records of very early domestic rice from Southeast Asia and
India (now known to be not so old as first reported). Proponents of the southern-origin theory
point out that early rice-farming societies along the Yangtze were already highly developed and
that evidence for the first stage of rice cultivation is missing. They argue that the first
hunter-gatherers to develop rice agriculture must have done so in this southern zone, within
the apparent present-day geographic range of wild rice.

Yet while most stands of wild rice reported in a 1984 survey were concentrated to the
south of the Yangtze drainage, two northern outlier populations were also discovered in
provinces along the middle and lower Yangtze, evidence that the Yangtze wetlands may fall
within both the present-day and the historical geographic ranges of rice's wild ancestor.

2.1. Which of the following, if true, would most clearly undermine the conclusion that the
author makes based on the 1984 survey?

A. Areas south of the Yangtze basin currently have less wild-rice habitat than they once did.

B. Surveys since 1984 have shown wild rice populations along the upper Yangtze as well as
along the middle and lower Yangtze.
C. The populations of wild rice along the Yangtze represent strains of wild rice that migrated to
the north relatively recently.
D. Early rice-farming societies along the Yangtze were not as highly developed as
archaeologists once thought.
E. In East Asia, the historical geographic range of wild rice was more extensive than the
present-day geographic range is.

2.2. Based on the passage, skeptics of the idea that rice cultivation began in the Yangtze River
region can point to which of the following for support?
A. Lack of evidence supporting the existence of rice-farming societies along the Yangtze at an
early date
B. Lack of evidence regarding the initial stages of rice cultivation in the Yangtze region
C. Recent discoveries pertaining to the historical geographic range of rice's wild ancestor
D. New information regarding the dates of very early domestic rice from Southeast Asia
E. New theories pertaining to how hunter-gatherers first developed rice agriculture in East Asia

2. 3. Which of the following can be inferred from the passage about the “southern-origin
theory”?
A. The theory is based on an unconventional understanding of how hunter-gatherers first
developed rice agriculture.
B. The theory fails to take into account the apparent fact that evidence for the first stage of rice
cultivation in the north is missing.
C. The theory was developed primarily in response to a 1984 survey of wild rice's geographic
range.
D. Reassessment of the dates of some archaeological evidence has undermined support for the
theory.
E. Evidence of sophisticated rice-farming societies in the Yangtze region provides support for
the theory.
