For a dog test to be effective, what has to be true? select all that apply.

umm nothing to cheak so i would say a e c

i believe the answer is: b. mr. head had a long, tube-like face with a rounded open jaw and a short depressed nose.

this is because in the un-revised sentence it said that mr. heads face was long and tube-like, and he had a rounded open jaw. this is not a very grammatically correct because of how it seems to drag on with the and, replaced with, with, makes it sound more fluent in the description.

it u understand what he thought at the time and let u know more about him then what third person would of known probably. hope this : )
