Prior to 1965 geologists assumed that the two giant rock plates meeting at the San Andreas Fault generate heat through friction as they grind past each other, but in 1965 Henyey found that temperatures in drill holes near the fault were not as elevated as had been expected. Some geologists wondered whether the absence of friction-generated heat could be explained by the kinds of rock composing the fault. Geologists' pre-1965 assumptions concerning heat generated in the fault were based on calculations about common varieties of rocks, such as limestone and granite; but "weaker" materials, such as clays, had already been identified in samples retrieved from the fault zone. Under normal conditions, rocks composed of clay produce far less friction than do other rock types.

In 1992 Byerlee tested whether these materials would produce friction 10 to 15 kilometers below the Earth's surface. Byerlee found that when clay samples were subjected to the thousands of atmospheres of pressure they would encounter deep inside the Earth, they produced as much friction as was produced by other rock types. The harder rocks push against each other, the hotter they become; in other words, pressure itself, not only the rocks' properties, affects frictional heating. Geologists therefore wondered whether the friction between the plates was being reduced by pockets of pressurized water within the fault that push the plates away from each other.

The passage suggests which of the following regarding Henyey's findings about temperature in the San Andreas Fault?

    A
    Scientists have yet to formulate a definitive explanation for Henyey's findings.这里的yet就是not的意思Some geologists wondered whether所以后面科学家只是探讨 并没有有definitive explanation

    in other words, pressure itself, not only the rocks' properties, affects frictional heating这里难道不是说Henry的结论不全面吗,难道不是B?

    原文中没有说yet啊,只是科学家的猜想啊

    选项A 正确,Geologists therefore wondered whether 这里的whether就是还没有形成决定性的解释的意思
    选项B  Henry’s explanation for the findings should be modified. henry并没有对自己的发现进行解释
    选项C 并不是因为实验要去改发现,实验是去试图解释这个发现的
    选项D provided support ,不是support,henry的发现和之前的地理学家是不符的
    选项E 科学家并不需要去复制henry的发现,
