Can someone help?

Source 1: primary

Source 2: secondary

Source 3: primary

Source 4: secondary

Source 5: primary

Source 6: primary

Primary sources are usually original thoughts and ideas. Secondary sources are usually thoughts and ideas about a primary source. A movie is a primary source; a video/article review of the movie is a secondary source.

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.
