Well since you don't give the passage, i can only assume you want to know what tumult means. tumult means, either a loud and confusing noise especially caused by a large crowd. or confusing/disorder
The correct answer is'C' because it just gives us additional information,If you remove it from the sentence,it will make perfect sense.
This would definitely be FALSE. Being able to distinguish the subjects and objects will help you to avoid confusion on which verb or pronoun to use. We always follow the rules in subject-verb agreement as well as the pronoun-antecedent rules. Knowing either the subject is plural or singular will give you an idea on what verb to use. Same goes with the antecedents and pronouns to use.
You should let us see what the choices are because it’s impossible to know
Mumble, the most livable character in the famous DreamWorks movie Happy Feet, has bright icy blue eyes, and is covered in black feathers EXCEPT for his front, which is a silver-grey to white in the middle. He has black feet and under his neck is a patch of dark grey feathers colored in the shape of a bow tie. Hope this helps!
