Item 4 Derek went to Peru with his parents to help build a school for local villagers. What is a likely outcome of this experience for Derek

You'd be surprised at how much influence ancient Greece has over modern day! Besides their mythology being incorporated into our products & media (see: the various Hercules movies, Percy Jackson, there's a cleaning product called Ajax, stronger than all of Grease!), it's safe to say that our government is inspired in part by the Greeks, who are credited with the first democracies. Like ancient Greeks, many modern countries vote for our leaders. 

Greek fathered modern philosophy & several famous mathematicians (though the Middle East were better versed in that regard.) 

Greeks also heavily influence modern theatre. And they invented the Olympics.
