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.
Correct answer is option 'C'. Can you explain this answer?

Astronomer: Among recently-observed stars, LV-426 has been exhibiting ...
The first thing that we should do is to define the argument, without which we cannot decide whether a BF is supporting or dismissing the argument.

The core argument finally is that the LV-426 is ripe to explode. "because it is now showing signs of turbulence" is the grounds on which this conclusion or argument is drawn.

However, look at E, The choice says that the info given in the second BF counters the argument. This is not so and is enough to eliminate the choice.
We must not be swayed by the fact that the first BF may be true. In BF, the premise and the inference should be congruous.

C. The first describes an occurrence that does not contradict the main conclusion of the argument; the second provides the reason for that conclusion.

In C, the first BF does not talk anything about the recent occurrence of the turbulence. It only talks about the quiet period that prevailed earlier. The second provides a reason for the main conclusion of an imminent explosion that is likely to occur because of the newly observed turbulence.
The catch in C is that the first part is neutral. It neither contradicts nor supports the core conclusion.
