PLEASE HELP ILL MARK BRAINIEST...Read the excerpt from "Diving With a Purpose: Resurrecting a Forgotten Maritime Heritage" from the National Park Service: In 2003, members of National Association for Black Scuba Divers (NABS) participated in the "Guerrero Project" documentary. The documentary centered on the search for the slave ship and its amazing story told through the book authored by Gail Swanson. The documentary also tells the story of treasure hunters and archeologists and their opposing views. In 2005, Kenneth Stewart of the Tennessee Aquatic Project (TAP) and the late Brenda Lanzendorf developed the Diving with a Purpose program. Lanzendorf was the only archeologist at Biscayne National Park at the time and was the "star" of the Guerrero Project documentary. The DWP was formed to help Lazendorf document shipwrecks in Biscayne. The park is the largest marine park in the National Parks systems. It contains over 110 archeological sites, of which 43 are intact shipwrecks. The Guerrero was wrecked on December 19, 1827, on a reef near Key Largo. It was carrying 561 enslaved Africans enroute to Cuba. Forty-one of the captive Africans drowned. During two expeditions in 2010 and 2012, DWP removed pieces of ceramics and glass, an iron shot, and wood samples to examine. A composite site map was developed. Research on the ship wreck is ongoing. The expedition was featured in the PBS "Changing Seas" documentary series episode "Sunken Stories". How does the author use ethos to achieve their purpose? *
