Astronomer: Among recently-observed stars, LV-426 has been exhibiting signs of turbulent activity. Prior to this observation, scientists speculated over whether LV-426 could become a supernova, but dismissed the possibility since
the star was dormant for a prolonged period of time. It now seems likely that LV-426 will explode into a supernova, since
turbulent surges of activity have been observed in every star that has transformed into a supernova.In the astronomer’s argument, which of the following roles do the boldfaced portions play?
A. The first provides evidence for a prediction defended by the argument; the second is that prediction.
B The first describes a situation supporting a conclusion that is reevaluated by the argument; the second is a counterargument made by the author.
C. The first describes an occurrence that does not contradict the main conclusion of the argument; the second provides the reason for that conclusion.
D The first gives information that supports an intermediate conclusion cited in the argument; the second states the reason for that conclusion.
E . The first provides evidence in support of an observation that is dismissed in the argument; the second provides information that counters that observation.
There is a same topic that is posted in a wrong forum and has no bold words.
E is a trap, no observation, no contradiction, no dismission, no counter-argument -> C
