Iggy is revising the following excerpt from his research-based essay on the effectiveness of animal shelters. Behaviorists studied sheltered animals to determine whether these animals showed increased signs of stress. These clinicians hypothesized that behaviors such as whale eye are much more prevalent in shelter inhabitants.

Which revisions should Iggy make to best improve the readability for his audience (tenth grade classmates and his teacher)?

-Iggy should include personal perspective of owning a shelter pet.

-He should combine the sentences to make the text easier to read.

-He should include extended definitions for more challenging vocabulary.

-He should include all behaviors of the stressed dogs observed by the clinicians.

Thanks :)
