Select the sentence that is written informally.

it is almost baseball season, and i am getting excited.
jane loves to go to the library to check out books.

the ground was frozen solid

D. The ground was frozen solid

Hope this helps :)

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.
