After reading excerpt represented above I can clearly see the right answer from the scale attached above. Definitely, this paragraph uses standart compare-contrast organization, so now it is clear that the only correct option is the first one A. Comparison and contrast; cause and effect. Especially such words<span> as "however" and "on the other hand" are the prompts for you to understand why I think so.</span>
All these words:
<em>Maritime, Marina, Marinate, Marinara, Marine, </em>and<em> Mariner</em>
Share the same Latin Root:
"Mare" which means "sea"
