The Langova National park is a breeding ground for several migratory birds. Of late, the Spot-breasted Laughing Thrush, an extremely rare species of bird, has been sighted only in the Langova National park. The people who have sighted this bird in the park have claimed that it is possible to sight this bird only through the use of binoculars. Barry is visiting the Langova National Park next week and he will be carrying an extremely powerful pair of binoculars with him. Therefore, it is safe to conclude that, as long as Barry has his binoculars on him, he will most definitely manage to sight the Spot-breasted Laughing Thrush.
Which of the following indicates a flaw in the reasoning above?
(A) It fails to take into account the possibility of sighting the Spot-breasted Laughing Thrush at places other than the Langova National Park.
(B) It mistakes a necessary condition for a sufficient condition.
(C) It is based on a series of assumptions, rather than on facts.
(D) It does not take into account the possibility that Barry could lose or damage his binoculars on the way to the park.
(E) It does not take into account the possibility that Barry may sight some other equally rare species of bird.

Most probably B
The usage of binoculars in this case is a sufficient case rather than a necessary case. You can have Binos and still not see the bird

The Langova National Park ( LNP) is a breeding ground for several migratory birds. In recent times, the Spot-breasted Laughing Thrush ( SBLT) an extremely rare species of bird, has been sighted only in the Langova National park (LNP).
Those, who have sighted the SBTL has been able to see it ONLY through the use of binoculars.
Barry, is planning his visit to the LNP next week, and is carrying an extremely powerful binoculars. So, they conclude that - Barry will be most definitely able to view SBLT.
what is the flaw in this reasoning ?
(A) It fails to take into account the possibility of sighting the Spot-breasted Laughing Thrush at places other than the Langova National Park.
Option A contradicts the fact that SBLT is spotted only in LNP. Hence, wrong.
(B) It mistakes a necessary condition for a sufficient condition.
Yeah- this is the valid reason. The availability of binoculars, presence at LNP are sufficient conditions for spotting SBLT and not necessary conditions.
(C) It is based on a series of assumptions, rather than on facts.
The question stem contains a sequences of facts supporting a conclusion, and not mere assumptions. Hence, wrong.
(D) It does not take into account the possibility that Barry could lose or damage his binoculars on the way to the park.
This is a probabilistic chance that it might happen or may not happen too. Hence, wrong.
(E) It does not take into account the possibility that Barry may sight some other equally rare species of bird.
This option is moving out of scope of the question and conclusion. Hence, wrong.
Option B
