The correct answer for the question that is being presented above is this one: "Looking through the boat's glass bottom, we saw brightly colored fish and even a small shark swim past us." The sentence that has a mismatch between subject and modifier is this "<span>Looking through the boat's glass bottom, we saw brightly colored fish and even a small shark swim past us."</span>
I'd say the second option:
written communication skills
Because it's an online way of communicating ad on discussion boards it's a group.
The answer would be "<span>Aiden is thrilled about starting a performance project on Romeo and Juliet, although he worries about getting assigned to a group of students who are poor actors." YOU'RE WELCOME :D
Sorry I took too long to answer :P</span>
The first one is right. it joins two independent clauses with a comma followed by a conjunction.
The answer is modern. Adjectives are defined as <span>a word/words or phrase/phrases naming an attribute, added to or grammatically related to a noun to modify or describe it. In other words, it describes a noun or modifies a noun. In this sentence, modern modifies or describes the noun Olympics. Greece, Athens, and Olympics are not adjectives because the are nouns in themselves.</span>
