求助：关于plausible和specious

plausible 和specious到底有什么区别呢？是一个是似是而非一个事似非而是？+_+
在阅读中哪个是正面态度，哪个是负面态度呢？
好晕哪，今天阅读做得不顺。。。
No 8-2 section B 的一道态度题涉及plausible
The term “Ice Age” may give a wrong impression. The epoch that geologists know as the Pleistocene and that spanned the 1.5 to 2.0 million years prior to the current geologic epoch was not one long continuous glaciation, but a period of oscillating climate with ice advances punctuated by times of interglacial climate not very different from the climate experienced now. Ice sheets that derived from an ice cap (ice cap: n. 〈地〉冰帽；冰冠a cover of perennial ice and snow; specifically: a glacier forming on an extensive area of relatively level land and flowing outward from its center) centered on northern Scandinavia reached southward to Central Europe. And Beyond the margins of the ice sheets, climatic oscillations affected most of the rest of the world; for example, in the deserts, periods of wetter conditions (pluvials) contrasted with drier, interpluvial periods. Although the time involved is so short, about 0.04 percent of the total age of the Earth, the amount of attention devoted to the Pleistocene has been incredibly large, probably because of its immediacy, and because the epoch largely coincides with the appearance on Earth of humans and their immediate ancestors.
There is no reliable way of dating much of the Ice Age. Geological dates are usually obtained by using the rates of decay of various radioactive elements found in minerals. Some of these rates are suitable for very old rocks but involve increasing errors when used for young rocks; others are suitable for very young rocks and errors increase rapidly in older rocks. Most of the Ice Age spans a period of time for which no element has an appropriate decay rate.
Nevertheless, researchers of the Pleistocene epoch have developed all sorts of (all sorts of:各种各样的) more or less fanciful model schemes of how they would have arranged the Ice Age had they been in charge of events. For example, an early classification of Alpine glaciation suggested the existence there of four glaciations, named the Gunz, Mindel, Riss, and Wurm. This succession was based primarily on a series of deposits and events not directly related to glacial and interglacial periods, rather than on the more usual modern method of studying biological remains found in interglacial beds themselves interstratified within glacial deposits. Yet this succession was forced willy-nilly onto the glaciated parts of Northern Europe, where there are partial successions of true glacial ground moraines and interglacial deposits, with hopes of ultimately piecing them together to provide a complete Pleistocene succession. Eradication of the Alpine nomenclature is still proving a Herculean task (herculean task: 需要付出巨大气力的工作;极为艰巨的工作).
There is no conclusive evidence about the relative length, complexity, and temperatures of the various glacial and interglacial periods. We do not know whether we live in a postglacial period or an interglacial period. The chill truth seems to be that we are already past the optimum climate of postglacial time. Studies of certain fossil distributions and of the pollen of certain temperate plants suggest decreases of a degree or two in both summer and winter temperatures and, therefore, that we may be in the declining climatic phase leading to glaciation and extinction.

27.
The author would regard the idea that we are living in an interglacial period as
(A) unimportant
(B) unscientific
(C) self-evident
(D) plausible（D）
(E) absurd
这个又是为什么选plausible呢？
麻烦大家帮看一下？

定位到最后一句：Studies suggest that we may be in leading to glaciation
plausible一般是有evidence但不conclusive，正向词
specious=plausible but false，负向词
specious在阅读里基本无

2# camsword 谢谢啦!这回弄懂了.plausible就是大概对的,但不绝对.
