I need a formal letter due tomorrow to a animal shelter :)) what can it be about ?

it depends on why you are sending the letter in the first place.

Explanation:

A formal letter to an animal shelter could be adopting some of the animals or what animals they have, questions about how they run their shop, questions about prices/how the process of adoption works, do I need any qualifications to adopt, ect.

Explanation:

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.
