Krieger helpfully "translates" for us something from Cabeza de Vaca's narrative. Which of the following does he describe?

$**$ I mean "translate" here in the sense of explanation; the narrative was of course originally in Spanish, but Krieger does not translate the work himself $**$

Cabeza de Vaca's interpretation of "skin drawings," which we now understand to be tattoos

Cabeza de Vaca's sighting of "bison," which he describes as an odd kind of cow

Cabeza de Vaca's insistence on learning medicine, which he saw as crucial for European$/$Native American relations

Narv$$ez$\text{'}$s failure, which the author claims was due to his not understanding Native American culture
