The main character is examining the deceased monkey looking for a cause of death and has found multiple blood rings on it's stomach and has narrowed the cause of death down to just two causes, Simian Fever or Ebola. Hope this helps!
B: he is confident about his abilities
The award-winning actor was infamous for throwing fits and not getting along with the cast.
Within The Tempest it is demonstrated that contact with native populations is rarely an even exchange; the native people are usually exploited in some way. This is demonstrated by the way that the "invaders" in the form of those who are shipwrecked at the beginning of the play attempt to change the islanders, little suspecting that one of them is the usurped Duke of Milan - now in the form of the wizard/magician Prospero.
To some extent it could also be argued that Prospero himself has already changed the nature of the island by being there. He has introduced magic, captures the monster Caliban and lies to his own daughter (allbeit it to protect her).
