5. The passage suggests which of the following about the paleoseismologists’ findings described in lines 42–50?
A. They suggest that the frequency with which earthquakes occurred at a particular site decreased significantly over the past two millennia.
'irregular' recurrence has been highlighted. There is no mention of decreasing trend.
B. They suggest that paleoseismologists may someday be able to make reasonably accurate long-term earthquake predictions.
No such prediction inferred from the particular extract of the passage concerning paleoseismologists
C. They suggest that researchers may someday be able to determine which past occurrences of minor tremors were actually followed by large earthquakes.
The paleoseismologists have not deliberated upon the past occurrences of minor tremors in connection with large earthquakes
D. They suggest that the recurrence of earthquakes in earthquake-prone sites is too irregular to serve as a basis for earthquake prediction.
Lines 48-50 (last paragraph) highlights the view of paleoseismologists : 'individual intervals ranged greatly from 44 to 332 years' --- highlighting evidently that the paleoseismologists thought that the recurrence of earthquakes in earthquake-prone sites is too irregular to serve as a basis for earthquake prediction.
E. They indicate that researchers attempting to develop long-term methods of earthquake prediction have overlooked important evidence concerning the causes of earthquakes.
There is no mention of evidence related to the causes of earthquakes in the particular extract of the passage .
The correct option is (D)

6. The author implies which of the following about the ability of the researchers mentioned in line 18 to predict earthquakes?
A. They can identify when an earthquake is likely to occur but not how large it will be.
Clearly highlighted in line 24 of the passage that 'foreshocks indicate nothing about the magnitude of an impending quake'
B. They can identify the regions where earthquakes are likely to occur but not when they will occur.
If the foreshocks are indistinguishable from other minor tremors that occur without large earthquakes (as highlighted in the passage), then the location can also not be determined.
C. They are unable to determine either the time or the place that earthquakes are likely to occur.
Lines 23-26 of the passage mention that such researchers' analyses later proved that the foreshocks are indistinguishable from other minor tremors that occur without large earthquakes -- if that be so, then it can be inferred that the researchers will be unable to determine either the time or the place that earthquakes are likely to occur.
D. They are likely to be more accurate at short-term earthquake prediction than at long-term earthquake prediction.
No such comparisons drawn regarding accuracy of short-term earthquake prediction over long-term earthquake prediction.
E. They can determine the regions where earthquakes have occurred in the past but not the regions where they are likely to occur in the future.
Determination of the regions where earthquakes have occurred in the past -- not discussed in connection with such researchers

Hi,
I had the same confusion as stonecold and I went through the explanation which largely makes sense, however, the option talks about them being able to identify when an earthquake is likely to occur and not that the earthquake occurs for sure. Wouldn't this make A more defensible?
