According to the cartoon, Shep 

  • a

    considers his friend boring. 

  • b

    thinks that humans are dumb.

  • c

    believes animais are inarticulate. 

  • d

    agrees with what his friend said about animais. 

  • e

    feels insulted because he thinks he is a human. 

Pode-se deduzir a partir do terceiro quadro do cartum:
"Intelligence of a human!? Come on! We are not that dumb!"
(Inteligência de um humano!? Ora! Não somos tão burros/idiotas!)
