Biomes around the world, written by University of Chicago environmental scientists in 2018 for high school classes

Explanation:

This is the best option because the first option was written by a student on a blog and is therefore not as reliable as the second source.

The last two options do not talk directly about biomes, which is what the project is about, making them poor options as well.

The second source is reliable and pertains to the topic, making it the best choice.

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.  

faulty coordination occurs when the writer gives equal importance two different ideas (clauses) which in fact are not equivalent. in order to correct a misplaced clause or idea, the writer can place less important or emphatic ideas in a relative clause as in the previous sentence.  

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.
