Nightjars possess a camouflage perhaps unparalleled in the bird world: by day they roost hidden in shady woods, so ------- with their surroundings that they are nearly impossible to -------.
(A) vexed . . dislodge
(B) blended . . discern
(C) harmonized . . interrupt
(D) impatient . . distinguish
(E) integrated . . classify
Answer (2)
B) Blended ... Discern.
Blended can mean to camouflage, meaning that the bird would be well hidden in its surroundings.
To discern would mean to be able to identify it apart from its surroundings.
The correct answer to the question is (B) blended . . discern, which effectively describes how nightjars merge with their surroundings, making them difficult to identify. This choice reflects the concept of camouflage appropriately. Thus, the sentence reads that nightjars are so blended with their surroundings that they are nearly impossible to discern.
