1) 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. Correct
Some scientists had speculated that since clay was found in San Andreas Fault and rocks composed of clay produce far less friction than do other rock types .
However , Byerlee tests at a depth of 10-15 km below the Earth’s surface showed otherwise . Geologists also wondered whether the friction between the plates was being reduced by pockets of pressurized water .
B. Recent research suggests that Henyey’s explanation for the findings should be modified. Incorrect
There is no recent research mentioned in the passage that suggest about modification
C. Henyey’s findings had to be recalculated in light of Byerlee’s 1992 experiment. Incorrect
There is no discussion on recalculations of Henyey’s findings .
D. Henyey’s findings provided support for an assumption long held by geologists. Incorrect
Against the idea of pre 1965 geologists .
E. Scientists have been unable to duplicate Henyey’s findings using more recent experimental methods. Incorrect
The passage does not discuss about replication of Henyey’s findings .
2) The passage is primarily concerned with
B. discussing explanations for an unexpected scientific finding . Correct Answer
The unexpected finding was Henyey’s that temperatures in drill holes near fault was lower than expected .
3. The passage mostly agree that Henyey’s findings about temperature in the San Andreas Fault made the greatest contribution in that they
A. revealed an error in previous measurements of temperature in the San Andreas Fault zone - 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.-- the temperature was not as high as expected (not as a previous measurement)
D. suggested that geologists had inaccurately assumed that giant rock plates that meet at the San Andreas Fault generate heat through friction - Correct
The passage was complicated . The third question was the most difficult .

Failed to get it correct even after taking 2 mins .
Got it correct on the second attempt
