Answer:
These hybrids were first seen in zoos.
Explanation:
Text structure is how information within a written text is organized.
From the excerpt, the text first began by giving an example of hybrid: the combination of polar bear and grizzlies to form a hybrid of grolar bears and prizzlies. It went further to discuss the differences between the original specie and hybrid and how the hybrids are more dangerous and were becoming a threat to their natural habitat and other animals.
From the text, we can infer that many hybrids become more dangerous and aggressive than the original specie/animal and the example of a wolfdog was given.
