On Monday, Elliot read 7x - 4 pages. On Friday, he read 4x - 8 pages. What is the difference in pages read?

if this is a true or false question its true

an expression designed to call something to mind without mentioning it explicitly; an indirect or passing reference.

often a noun phrase is just a noun or a pronoun:

people like to have money.

i am tired.

it is getting late.

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.
