What kind of sentence structure is this: at that night, there was a gathering.

is it a simple, compound, complex, or compound-complex sentence. why?

for me i cant do homework without music, so, i guess i would say faster with it, than without it. for me at least.

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.
