The answer should be A. This is because the other sentences don't need any word except for the first word in its sentence.

"<span>It was started in 2009 by actor Matt Damon and Gary White, the co-founder of Water Partners."</span>
        
                    
             
        
        
        
Answer:
Othello fits the description of a tragic hero.
Explanation:
A hero is a character who has the ability to accomplish great things. A tragic hero is no different, since he has this ability. However, the great deeds of a tragic hero result in suffering and the disgrace of him and those around him.
Othello is a perfect example of a tragic hero, since his actions lead to himself and the people he loves death. Othello causes misfortune by acting out of jealousy, arrogance, lack of critical sense, remorse and impulsiveness. This all causes very bad effects through great actions.
