1. The author is primarily concerned with:
A. enumerating how an unconventional means solved one of the volcanology’s most enduring mysteries.INCORRECT INCONSISTENT: The focus of the passage is not on the unconventional method.
B. explaining how researchers could finally trace the Samalas event.CORRECT.
C. describing one of the deadliest volcanic eruptions that took place in mid-13th century. INCORRECT OUT OF SCOPE: The author does not describe about the eruption of Samalas but describes how researchers could get to Samalas.
D. presenting the nature of volcanic spew of the 1257 volcano eruption in comparison with that of the other major volcanic event.INCORRECT PARTIAL SCOPE: This point is covered only in paragraph 2 & 3 just to mention the scope of the 1257 AD eruption.
E. showing through major volcanic events how deadly the eruption of the 1257 AD was.INCORRECT PARTIAL SCOPE: The comparisons are made only in the second and third paragraphs.[/spoiler]
2. The author of the passage alludes to the discovery made in Greenland and Antarctica in order to
A. suggest that the researchers explored these sites to accumulate traces and study effects of the massive 1257 AD eruption.INCORRECT OPPOSITE: This choice reverses the cause-effect.
B. indicate that the sharp increase in the levels of sulfate in stratosphere must have been due to massive volcanic eruption in 1257 AD.CORRECTC. point massive eruptions can affect vast areas of land.INCORRECT OUT OF SCOPE: This is certainly not the reason why the author talks about Greenland and Antarctica.
D. compare the effects of 1257 AD eruption with that of eruption in these two locations.INCORRECT OUT OF SCOPE: The passage does not mention that these two places witnessed volcanic eruptions.
E. bring in the importance of these places in the resolution of the mystery of 1257 AD eruption.INCORRECT OUT OF SCOPE: These places certainly did not help in resolving the mystery.[/spoiler]
3. Which of the following statements about “the most intense historic volcanic event” is supported by information in the passage?
A. The ejecta from this volcanic eruption led to pyroclastic deposits more than 100 feet thick that were found more than 15 miles away from the site of the volcano.INCORRECT OUT OF SCOPE: This statement is true of Samalas eruption in 1257 AD.
B. This event took place in 1883 and led to significant increase in sulfate in stratosphere.INCORRECT OUT OF SCOPE: This statement is about the eruption of Karaktau volcano.
C. The event is chronicled in Babad Lombak, a 13th century historical record in Old Javanese.INCORRECT OUT OF SCOPE: This statement is again true of Samalas eruption in 1257 AD.
D. The event refers to Tambora event that took place in 1815 and is included in the history of massive volcanic eruptions.INCORRECT OUT OF SCOPE: Tambora is not mentioned as the “most historic volcanic event” in the passage.
E. This event took place in the Taupo Volcanic Zone of New Zealand in 2nd century AD.CORRECT
