A scientific study provides evidence that crows are capable of recognizing threatening people and can even pass their concerns on to other crows. Researchers wearing rubber caveman masks trapped wild crows and then released them in the same area. Years later, people wearing the same masks near where the crows had been trapped were shrieked at and dive-bombed by crows.
The argument depends on the assumption that
A. some of the crows that shrieked at and dive-bombed people wearing the masks were not among the crows that had been trapped
B. crows that perceive an individual as threatening always respond by shrieking and dive-bombing
C. most birds of any species will regard a person as threatening if they see crows shrieking at and dive-bombing that person
D. even in places where crows have never been captured, most crows will shriek at and dive-bomb people wearing caveman masks
E. crows can distinguish between people who are wearing caveman masks and those who are not, but they cannot recognize individual human faces
The argument depends on the assumption that
A. some of the crows that shrieked at and dive-bombed people wearing the masks were not among the crows that had been trapped
B. crows that perceive an individual as threatening always respond by shrieking and dive-bombing
C. most birds of any species will regard a person as threatening if they see crows shrieking at and dive-bombing that person
D. even in places where crows have never been captured, most crows will shriek at and dive-bomb people wearing caveman masks
E. crows can distinguish between people who are wearing caveman masks and those who are not, but they cannot recognize individual human faces

Prethinking
The argument wants to prove that crows remember people who were a threat to them and can also pass it on to other crows.
After creating a threat in the crows by wearing the masks and capturing them, after years people wearing masks were attacked. Now there can be ample reasons why the crows might have attacked them. But to admit to the authors argument, these crows should be the same crows or some other crows, as the argument suggests that they do remember and pass on the threats.
The argument depends on the assumption that
A. some of the crows that shrieked at and dive-bombed people wearing the masks were not among the crows that had been trapped
This is matching exactly to what we pre-thought. If some were other crows then it very well addresses 2 things - 1. that crows remember threats 2. They pass on threats.
B. crows that perceive an individual as threatening always respond by shrieking and dive-bombing
If responding to individual threat is a nature of the crow itself. Then the experiment mentioned in the argument doesnt conclude anything fruitful.
C. most birds of any species will regard a person as threatening if they see crows shrieking at and dive-bombing that person
The observation of the crows by other birds is not relevant and its not what we are talking about in this promt.
D. even in places where crows have never been captured, most crows will shriek at and dive-bomb people wearing caveman masks
Again, its some inherent trait of the crows that they respond this way they see people wearing caveman masks.
E. crows can distinguish between people who are wearing caveman masks and those who are not, but they cannot recognize individual human faces
The first part seems relevant. Something the argument does discuss. But recognizing individual faces is something not relevant.

Imo option b is correct by negating option b shows shrieking and dive bombing are not threatening actions
