Balboa thinks about cristóbal colón, vespucci, and the pizarro brothers in lines 33-36 because select one: a. he competes with them for power. b. he considers himself a great explorer. c. they are members of balboa's expedition. d. they have followed balboa to the new world.

I think it is because Balboa considers himself a great explorer like Cristobal Colon  (Cristopher Columbus) and Vespucci and the Pizarro brothers. the Of course Cristobal Colon discovered the Americas as did Vespucci whose first name was Amerigo so America was named after him. The Pizarro brothers discovered Peru with its' riches of gold and silver and the empire of the Incas.,Balboa was the first explorer to reach the Pacific Ocean by land over the isthmus of Panama. He later founded a settlement in Panama.
