Volcanic rock that forms as fluid lava chills rapidly is called pillow lava. This rapid chilling occurs when lava erupts directly into water (or beneath ice) or when it flows across a shoreline and into a body of water. While the term ―pillow lava‖ suggests a definite shape, in fact geologists disagree. Some geologists argue that pillow lava is characterized by discrete, ellipsoidal masses. Others describe pillow lava as a tangled mass of cylindrical, interconnected flow lobes. Much of this controversy probably results from unwarranted extrapolations of the original configuration of pillow flows from two- dimensional cross sections of eroded pillows in land outcroppings. Virtually any cross section cut through a tangled mass of interconnected flow lobes would give the appearance of a pile of discrete ellipsoidal masses. Adequate three- dimensional images of intact pillows are essential for defining the true geometry of pillowed flows and thus ascertaining their mode of origin. Indeed, the term ―pillow,‖ itself suggestive of discrete masses, is probably a misnomer.

3. The author implies that the ―controversy‖ might be
resolved if
(A) geologists did not persist in using the term
―pillow‖
(B) geologists did not rely on potentially misleading
information
(C) geologists were more willing to confer directly
with one another
(D) two-dimensional cross sections of eroded
pillows were available
(E) existing pillows in land outcroppings were not
so badly eroded


正确答案选B，我选了E。
我是这样想的：
定位到Much of this controversy probably results from unwarranted extrapolations of the original configuration of pillow flows from two- dimensional cross sections of eroded pillows in land outcroppings.
然后作者之后说 Adequate three- dimensional images of intact pillows are essential for defining the true geometry of pillowed flows and thus ascertaining their mode of origin.
说明intact pillows的images可以解决问题，那么eroded pillows就是controversy存在的原因。

Sorry! 我打字的时候敲错了，正确答案是B...
但是E为什么不对呢？

其实这题我也做错了，但是我觉得那个controversy的点在于“没有3d image”而不是“intact or eroded”。LZ随意参考下吧

我又想了一下....
results from 后面直接跟的是unwarranted extrapolations，说明unwarranted extrapolations才是直接原因，后面的信息都是次要的。不知道这样想对不对......

这道题最重要的应该是单词unwarranted,反正第一眼看到这个句子的时候，我的第一反应就是争执的原因就在于他们信息的错误。
